Description

METHOD AND APPARATUS FOR DISTRIBUTED GENERATOR PLANNING

BACKGROUND OF THE INVENTION

Field of the Invention

[0001] Embodiments of the present disclosure relate generally to distributed generators (DGs) and, more particularly, to a method and system for planning DGs.

Description of the Related Art

[0002] Use of distributed generators (DGs) to produce energy from renewable resources is steadily gaining commercial acceptance due to the rapid depletion of existing fossil fuels and the increasing costs of current methods of generating power. One such type of DG may be utilized within a solar power system, where each DG in the solar power system is comprised of photovoltaic (PV) modules that convert solar energy received from the sun into a direct current (DC). A power converter then converts the DC current from the PV modules into a direct current (DC) or an alternating current (AC), and the resultant power generated by the DGs may be stored for later use, used to run appliances at a home or business, or may be sold to the commercial power company.

[0003] Deployment of DGs for generating solar power is becoming increasingly widespread and involves a wide range of tasks leading up to the deployment. For example, sales leads must be managed, each potential DG system must be individually designed based on requirements specific to the particular installation, such as budget, location, and the like, and customer proposals must be generated. Such activities as well as associated information must be coordinated and tracked in order to efficiently manage each DG installation.

[0004] Therefore, there is a need in the art for a system for efficiently planning a DG system installation. SUMMARY OF THE INVENTION

[0005] Embodiments of the present invention generally relate to a method and apparatus for distributed generator (DG) planning. In one embodiment, the apparatus comprises (i) at least one interface for sizing a potential DG; (ii) at least one interface for designing the potential DG; and (iii) at least one interface for generating a proposal for the potential DG.

[0014] Figure 1 is a block diagram of a system 100 for managing and planning distributed generators (DGs) in accordance with one or more embodiments of the present invention. The system 100 comprises a plurality of distributed generators (DGs) 102_!, 102₂, ... 102_n. (hereinafter, DGs 102), a plurality of potential DGs 104_{1 ;} 104₂, 104_m, (hereinafter, potential DGs 104), a network operations center (NOC) 106, a user 1 10, and a satellite imagery source 1 16, all communicatively coupled via a communications network 1 14, e.g., the Internet.

[0015] The DGs 102 are DGs that are either in the process of being installed and turned-up for operation or are fully installed and operational. Each DG 102, once fully installed and operational, generates power from one or more renewable resource, such as solar energy, wind energy, hydroelectric energy, and the like. The generated power may be used to operate appliances in a home or business, coupled to a commercial power grid and sold to the commercial power utility, or a combination of both. Additionally or alternatively, the generated power may be stored for later use (e.g., utilizing batteries, heated water, hydro pumping, H₂0-to- hydrogen conversion, or the like).

[0016] In some embodiments, a DG 102 is comprised of a plurality of solar panels arranged in groups as solar arrays, where each solar panel is comprised of one or more power converters coupled to one or more photovoltaic (PV) modules in a one-to-one correspondence. The power converters may be DC-DC converters, DC-AC converters, or some combination of DC-DC and DC-AC converters. In one or more alternative embodiments, multiple PV modules may be coupled to a single power converter (i.e., a centralized power converter).

[0017] The potential DGs 104 represent possible future DG systems that are currently in a planning phase. Such a planning phase may range from an earliest indication of a sales lead for a DG system through a final DG system proposal made to a customer and a subsequent signed contract for the DG system.

[0018] The NOC 106 is a centralized operations management center for the DGs 102 and 104. The NOC 106 comprises a DG management and planning system 108 accessible by one or more users via a website, such as the user 1 10 utilizing a conventional web browser 1 12. In accordance with one or more embodiments of the present invention, the DG management and planning system 108 provides operative control and monitoring of the existing DGs 102, as well as planning functions for the potential DGs 104. Such planning functions, described in greater detail below, may comprise designing a DG for a specific location and may use satellite imagery obtained from a satellite imagery source 1 16, such as GOOGLE EARTH or MICROSOFT VIRTUAL EARTH, as well as map imagery (e.g., obtained from an Internet source, such as YAHOO! MAPS), and/or hybrid (satellite and map) imagery; in some embodiments, such satellite and/or map imagery may be retrieved from the corresponding source for use by the DG management and planning system 108 in real time. In some alternative embodiments, the DG management and planning system 108 may reside in a separate location from the NOC 106 and be communicatively coupled to the NOC 106, and/or the functions for managing existing DGs 102 and the functions for planning potential DGs 104 may reside in separate systems.

[0019] Figure 2 is a block diagram of a DG management and planning system 108 in accordance with one or more embodiments of the present invention. The DG management and planning system 108 comprises a central processing unit (CPU) 204 coupled to a transceiver 202, support circuits 206, and a memory 208. Additionally, the transceiver 202 is coupled to the DGs 102 via the communications network 1 14 for bi-directional communication with the DGs 102, e.g., for sending operative commands to the DGs 102, receiving performance data from the DGs 102, and the like. The transceiver 202 may utilize wireless or wired techniques for such communication. The DG management and planning system 108 may be implemented using a general purpose processor that, when executing particular software, becomes a specific purpose processor for performing various embodiments of the present invention.

[0020] The CPU 204 may comprise one or more conventionally available microprocessors. Alternatively, the CPU 204 may include one or more application specific integrated circuits (ASICs). The support circuits 206 are well known circuits used to promote functionality of the CPU 204 and may include, but are not limited to, a cache, power supplies, clock circuits, buses, network cards, input/output (I/O) circuits, and the like.

[0021] The memory 208 may comprise random access memory, read only memory, removable disk memory, flash memory, and various combinations of these types of memory. The memory 208 is sometimes referred to as main memory and may, in part, be used as cache memory or buffer memory. The memory 208 generally stores the operating system (OS) 210 of the DG management and planning system 108. The OS 210 may be one of a number of commercially available operating systems such as, but not limited to, SOLARIS from SUN Microsystems, Inc., AIX from IBM Inc., HP-UX from Hewlett Packard Corporation, LINUX from Red Hat Software, Windows 2000 from Microsoft Corporation, and the like.

[0022] The memory 208 may store various forms of application software, such as a DG management module 212 and a DG planning module 214. Additionally, the memory 208 may store a database 250 for storing data related to the present invention.

[0023] The DG management module 212 provides operative control of the existing DGs 102, for example, by generating signals to control the operation of individual components within the DGs 102. Additionally, the DG management module 212 provides monitoring for the DGs 102, for example, by receiving and processing performance data from the DGs 102 for display and/or long term storage in the database 250. [0024] The DG planning module 214 provides functionality to plan, design, and track status of the potential DGs 104, for example via a series of display screens described in detail with respect to Figure 3, from the earliest indication of a possible DG sale up to deployment of a committed DG (e.g., through a signed contract with a customer). Such functionality enables a user to expedite the sales qualification process, streamline the creation of sales proposals, create professional-quality customer-facing proposals, reduce errors and inconsistencies in solar array design, and support new staff during the training period.

[0025] The DG Planning Module 214 contains dashboard module 216, systems overview module 218, site overview module 220, roof space module 222, array size module 224, budget/cost module 226, components module 228, checklist module 230, initial proposal module 232, site evaluation module 234, component selection module 236, array layout module 238, budget calculator module 240, and proposal module 242; in some embodiments, the DG Planning Module 214 may additionally contain a create array module 252 (shown as a dashed box in Figure 2). Each module comprises software code - source or object code - that when executed by the CPU 204 provides the functionality described below with respect to Figures 3, 4, and 5, and, in some embodiments, Figure 6. In one embodiment, execution of the software code of a module enables a general purpose computer to operate as a specific purpose computer.

[0026] In some embodiments, the database 250 comprises satellite imagery data, obtained from the satellite imagery source 1 16, and/or map imagery (e.g., obtained from an Internet source) needed for graphics and images generated by the DG planning module 214; in other embodiments, such satellite and/or map imagery may not be stored within the database 250 and may be retrieved from the corresponding source for use in real time. Additionally, the database 250 may store user-generated data generated via the DG planning module 214, such as draft DG designs, notes pertaining to a potential DG 104, and the like. [0027] In some other embodiments, the DG management module 212 and the DG planning module 214 may reside within different systems. For example a DG management system may comprise a CPU coupled to a transceiver, support circuits, and a memory that comprises the DG management module 212; and a separate DG planning system may comprise a CPU coupled to a transceiver, support circuits, and a memory that comprises the DG planning module 214.

[0028] Figures 3A-3V depict a series of display screens 300 for planning installation of DGs in accordance with one or more embodiments of the present invention. The display screens 300 are generated by the DG planning module 214 upon a successful login to a website (e.g., a DG management and planning website) by the user 1 10. In some embodiments, one or more portions of the display screens 300 may be generated in conjunction with the DG management module 212; for example, one or more of the display screens 300 may display information pertaining to managing existing DGs 102. Although the display screens 300 described below are directed to planning installation of a solar power DG, the DG planning module 214 may additionally or alternatively generate analogous display screen for planning other types of DGs, such as wind farms, hydroelectric systems, or the like.

[0051] The budget/cost screen 352 is an interface to the executable budget/cost module 226 that, when executed, provides the user 1 10 the ability to determine financial incentives and costs (i.e., a financial size) associated with a potential DG 104 based on a possible size of the potential DG 104. The budget/cost screen 352 comprises a budget/cost summary window 354 for displaying financial costs and savings associated with a potential DG 104 based on the installation size. For example, for a potential DG 104, costs and savings for installations sized to achieve various utility power offset percentages, such as 100% offset, 50% offset, and a user-customizable offset, are displayed in the budget/cost summary window 354. For each installation size, the budget/cost summary window 354 displays the corresponding customer-specific system and financial parameters, such as system size (e.g., in kilowatt-hours), total cost, utility rebate, state rebate, federal tax credit, state tax credit, and net cost. In some other embodiments, other additional and/or alternative parameters may be displayed.

[0052] The budget/cost screen 352 further comprises a priority reminder display 351 for indicating customer priorities related to the potential DG 104 and corresponding areas of focus during the DG planning (e.g., the customer places a high priority on financial aspects of the DG system and thus focus should be on payback and IRR), a view payback button 353 for selecting a display of financial payback for the customer, and a view internal rate of return (IRR) button 355 for selecting a display of the IRR for the customer. [0053] In some embodiments, one or more of the screens shown in figures 3F-3I may be generated by a separate module, such as a commercially available module manufactured by Clean Power Finance, Clean Power Research, or SolarNexus, or a similar commercially available module.

[0054] Figure 3H depicts the budget/cost screen 352 comprising a simple payback window 356 obtained by selecting the view payback button 353 previously described. The simple payback window 356 depicts a graphical display of dollar savings per year for various sized installations of a potential DG 104, for example, for each of a 3 kilowatt, 6 kilowatt, and 9 kilowatt DG. Additionally, the simple payback window 356 comprises the view IRR button 355 as well as a script icon 339 for displaying corresponding talking points for use during customer interactions.

The method 400 represents one embodiment of an implementation of the DG planning module 214. In some embodiments, a computer readable medium comprises a program that, when executed by a processor, performs at least a portion of the method 400 that is described in detail below.

[0083] The method 400 begins at step 402 and proceeds to step 404, where a dashboard screen, such as the dashboard screen 302, is displayed to a user. The dashboard screen provides an interface for the user to manage daily work tasks related to planning for potential DGs (such as DGs 104). In some embodiments, the dashboard screen may be displayed when the user logs into a website (e.g., a website that supports DG system planning) via a conventional web browser. The dashboard screen may additionally display information related to existing DG systems (for example, information as supported by the DG management module 214), although in some embodiments, such as the embodiment described with respect to Figure 4, the dashboard screen is used for planning potential DGs.

[0084] The dashboard screen may comprise a plurality of windows for displaying various work areas, such as a message window for displaying alerts on issues requiring attention, information messages on news and resources, corporate happenings, and the like; a community window for displaying community-related information, such as links to peer-to-peer forums, links to social networking, and the like; and a sites window for displaying a summary of site statistics for existing and/or potential DGs, such as summaries of the number of DGs at each of a plurality of DG lifecycle stages (e.g., Stage 0 - Lead, Stage 1 - Design, Stage 2 - Installation, Stage 3 - Activation, and Stage 4 - Monitor), summaries of the number of DGs experiencing events of various severities (e.g., high, medium, and low severities), and the like. In some alternative embodiments, the dashboard screen may display additional and/or alternative windows, such as a summary of metrics for providing a comparison of the user's average DG installation times versus average DG installation times of other employees.

[0085] The method 400 proceeds to step 406, where a user selects additional information to be displayed by selecting an icon, link, or the like, from the message window, the community window, or the sites window. If the user selects additional information from the messages window, the method 400 proceeds to step 408 where the desired message information is displayed, and then proceeds to step 414. If, at step 406, the user selects additional information from the community window, the method 400 proceeds to step 410 where the desired community information is displayed, and then proceeds to step 414. At step 414, the user selects whether to return to the dashboard screen or to end the current session; if the user selects to return to the dashboard screen the method 400 returns to step 404, while the method 400 proceeds to step 499 and ends if the user selects to end the current session. [0086] If, at step 406, the user selects additional information from the sites window for potential DGs (i.e., information pertaining to the systems summary), the method 400 proceeds to step 420 where a systems overview window, such as the systems overview window 314, is displayed.

[0087] The systems overview window displays summary information pertaining to one or more potential DGs. The systems overview window may additionally display information related to existing DG systems (for example, information as supported by the DG management module 214), although in some embodiments, such as the embodiment described with respect to Figure 4, the systems overview window is used for planning potential DGs. In some embodiments, the systems overview window displays an identification, such as a customer name and location, for each DG displayed, as well as a corresponding lifecycle stage and next step. Additionally, the systems overview window may display icons and/or links for one or more actions a user may take regarding a particular DG system displayed, such as an envelope icon for generating an email, a trash can icon for disposing of information, a clipboard icon for opening a document, a window icon for opening an additional window, and the like.

[0088] The method 400 proceeds to step 422, where the user selects a potential DG of interest from those listed in the systems overview window, such as a potential DG currently in a planning stage. The method 400 then proceeds to step 424, where the user selects a DG planning category from a plurality of DG planning categories displayed, such as site, phone qualification, site evaluation, system design, and proposal, to view a corresponding screen for planning the potential DG. If, at step 424, the user selects the "site" category, the method 400 proceeds to step 426, where a site overview screen, such as the site overview screen 324, is displayed for the potential DG.

[0089] The site overview screen displays high-level information pertaining to the selected DG. Such information may be displayed within a plurality of windows such as a lead details window, a satellite window, a PV goals window, and a notes window; in some embodiments, additional or alternative windows may be displayed.

[0090] The lead details window may display a plurality of fields that contain details pertaining to the selected DG, such as the customer's name, address, utility provider, phone contact, email contact, and electricity usage, as well as a lead source and a reminder regarding a timeframe for contacting the customer; in some embodiments, an automatic notification to the user may be triggered based on the timeframe in the reminder field. The user may enter new data into one or more of the displayed fiends, and/or one or more of the fields may be automatically populated with data previously stored in a system database. The user may enter or change data in any of the fields using well known data entry methods (e.g., manual entry, importing data, drop-down menus, and the like), and the user may save the data in the fields at any time.

[0091] The lead details window may additionally display a driving directions icon for linking to driving directions to the customer's location. In some embodiments, the driving directions may be pre-stored within a system database; alternatively, the driving directions may be obtained in real-time via existing Internet services, such as MAPQUEST.

[0092] The satellite window may display satellite imagery of the potential DG's location (e.g., as obtained from stored data or real-time via existing Internet sources, such as GOOGLE EARTH or MICROSOFT VIRTUAL EARTH). The satellite imagery may be automatically obtained based on data entered in one or more fields within the lead details screen, such as the address. The satellite window may display options for viewing the satellite imagery, such as selecting different views (e.g., north/south/east/west views), rotating a displayed view, zooming in or out of a displayed view, panning across a displayed view, or perform a similar operation. Additionally or alternatively, the satellite window may display map imagery and/or hybrid (satellite and map) imagery. [0093] The notes window provides an interface for the user to document and save information pertaining to the potential DG (e.g., notes on discussions held with the customer, attempts to contact the customer, and the like). The PV goals window displays a plurality of attributes related to a DG (e.g., environmental, energy reduction, investment value, and aesthetic) and the priority of each attribute from the customer's perspective (e.g., low, medium, high).

[0094] The method 400 proceeds from step 426 to step 428, where a determination is made whether to continue with the DG planning. If the result of such determination is yes, the method 400 returns to step 424; if the result of such determination is no, the method 400 proceeds to step 499 where it ends.

[0095] If, at step 424, the user selects the "phone qualification" category from the DG planning categories, the method 400 proceeds to step 430, where a plurality of qualification tabs (such as qualification tabs 338) are displayed. The qualification tabs allow the user to select particular screens for use in the qualification of the potential DG.
