Description

风储联合惯量响应方法和惯量响应装置 技术领域
本公开总体说来涉及风力发电技术领域，更具体地讲，涉及风储联合惯量响应方法和惯量响应装置。
背景技术
随着风电技术的发展，电力系统中风电渗透率不断增加，风电带来的问题也不断涌现。传统风力发电机组采用传统的最大功率点跟踪(MPPT)控制策略且通过低惯性的电力电子设备接入电网，风力发电系统与电网几乎解耦，降低了系统惯性，使风场几乎不响应电网中的频率波动。另一方面，风电固有的随机性、波动性等特点也对电网安全稳定运行造成了威胁。
近年来，已经提出采用风机转子释放转子动能来做惯量响应，以维持电力系统频率稳定。图1是示出现有的惯量响应过程的示图。在图1中，f表示电网频率，P表示风力发电机组实时上网频率，P n表示风力发电机组额定功率，虚线表示电网频率，实线表示实时上网频率。在初始阶段，电网频率f保持在额定频率f n。其后，电网频率发生斜坡下降。一旦电网频率发生变化，就可以确定频率变化率，进而确定惯量响应需求功率ΔP(通常限定ΔP≤10％P n)。然后，可以以ΔP为控制目标对转子进行控制，转子功率随之发生变化，并通过变流器传输到网侧，体现为实时上网功率P逐渐上升，最终达到稳态。一般来说，从频率开始变化到P响应完成的时间间隔不允许超过固定值(例如，200ms)。当电网频率下降到一定程度时，不再变化，并且随后恢复到额定频率。这时，惯量响应需求功率ΔP清零，实时上网功率恢复。
然而，如上所述的现有惯量响应方法完全依赖转子动能，当惯量需求大时，对风力发电机组载荷的冲击将会很大。另外，因为最大转子动能有限制，因此当惯量需求大时，会出现响应不足的问题。另外，现有惯量响应方法采用开环固定给定方式执行，在风速波动时，上网功率无法稳定，而在功率稳态期间也会存在控制偏差。

下面对根据本公开的实施例的风储联合惯量响应方法的原理进行解释。
图2是示出根据本公开的实施例的风储联合惯量响应方法的原理的示图。
根据本公开的实施例的风储联合惯量响应方法通过包括风力发电机组和连接到风力发电机组的储能装置的风储联合系统进行惯量响应，能够够降低由于惯量响应导致的载荷冲击，并且能够提升惯量响应能力。在图2中，储能装置连接到变流器直流母线，然而本公开不限于此，储能装置也可以连接到其他位置。
参照图2，电网电压e_abc可输入到频率检测模块，以检测电网频率f，并且可基于电网频率f的变化率，计算惯量响应需求功率ΔP。这里，可以通过各种现有方法从电网电压e_abc检测电网频率f，进而确定电网频率的变化率，本公开对此不做任何限制。稍后将对计算惯量响应需求功率ΔP的方法进行具体描述。随后，可将惯量响应需求功率ΔP分解成ΔPgen和ΔPbat两个功率增量。这里，ΔPgen表示通过对风力发电机组的转子进行控制而产生的功率增量，ΔPbat表示通过对储能装置进行控制而产生的功率增量。可以将ΔPgen和ΔPbat作为转子控制目标和储能控制目标，通过转子控制系统和储能控制系统对转子和储能装置进行控制，产生相应的功率增量。
根据本公开的实施例，使用转子和储能装置来满足惯量响应需求功率。在惯量响应过程中，优先使用储能装置进行惯量响应而无需转子参与，以消除由于转子进行惯量响应而导致的对风力发电机组载荷的冲击。另一方面，当惯量响应需求很大时，可以通过转子进行补充的惯量响应，以提升惯量响应支撑能力。下面对根据本公开的实施例的风储联合惯量响应方法进行详细描述。
图3是示出根据本公开的实施例的风储联合惯量响应方法的流程图。
参照图3，在步骤S301中，响应于检测到电网频率发生变化，确定风储联合系统的惯量响应需求功率ΔP。如上所述，风储联合系统包括风力发电机组以及连接到风力发电机组的储能装置。当检测到电网频率发生变化时，可计算电网频率的变化率df/dt(即，频率导数f’)，并且基于电网频率的变化率df/dt、电网额定频率f n、风力发电机组的惯量常数T J和并网额定功率P n，确定风储联合系统的惯量响应需求功率ΔP。具体地讲，可通过如下公式(1)来计算惯量响应需求功率ΔP。
Figure PCTCN2022080619-appb-000001
接下来，在步骤S302中，可基于确定的惯量响应需求功率ΔP通过前馈反馈控制方式对储能装置和风力发电机组的转子进行控制，以产生功率增量，从而满足惯量响应需求功率ΔP。
图4是示出通过前馈反馈控制方式对储能装置和转子进行控制的示图。
如图4所示，可以以确定的惯量响应需求功率ΔP作为给定值，以风力发电机组的实时上网功率值P grid与确定风储联合系统的惯量响应需求功率时的上网功率值P last之差作为反馈值，通过比例积分微分(PID)运算计算第一控制分量，然后可以以确定的功率增量ΔP作为前馈量，并将前馈量与第一控制分量之和计算为储能转子联合控制目标ΔP*，最后可以基于计算的储能转子联合控制目标ΔP*，对储能装置和转子进行控制，以产生功率增量。这里，实时上网功率可基于风力发电机组的变流器机侧功率和功率增量来确定。例如，可将风力发电机组的变流器机侧功率和功率增量之和确定为实时上网功率。
这样，通过反馈控制，实现了对储能装置和转子的闭环控制(包括前馈控制与反馈控制)，提高了响应速度并且确保了响应的稳定度。
这里，在对储能装置进行控制时，可通过控制储能装置吸收电能或释放储存的电能，来产生相应的功率增量，在对转子进行控制时，可通过控制转子电磁转矩，来产生相应的功率增量。上述吸收/释放电能的控制方式以及电磁转矩的控制方式为本领域技术人员熟知，因此不再赘述。
如上所述，在惯量响应过程中，优先使用储能装置进行惯量响应。因此，当计算的储能转子联合控制目标ΔP*小于等于储能装置所能提供的最大功率增量ΔPbat_max时，可基于计算的储能转子联合控制目标ΔP*仅对储能装置进行控制，以产生功率增量ΔPbat。
当计算的储能转子联合控制目标ΔP*大于储能装置所能提供的最大功率增量ΔPbat_max且小于等于储能装置所能提供的最大功率增量ΔPbat_max与转子所能提供的最大功率增量ΔPgen_max之和时，可以以储能装置所能提供的最大功率增量ΔPbat_max作为储能装置控制目标对储能装置进行控制，并以储能转子联合控制目标ΔP*与储能装置所能提供的最大功率增量ΔPbat-_max之差作为转子控制目标对转子进行控制，以产生功率增量。在这种情况下，功率增量可以是通过对储能装置进行控制而产生的功率增量ΔPbat与通过对转子进行控制而产生的功率增量ΔPgen之和。
当计算的储能转子联合控制目标ΔP*大于储能装置所能提供的最大功率增量ΔPbat_max与转子所能提供的最大功率增量ΔPgen_max之和时，可以以储能装置所能提供的最大功率增量ΔPbat_max作为储能装置控制目标对储能装置进行控制，并以转子所能提供的最大功率增量ΔPgen_max作为转子控制目标对转子进行控制，以产生功率增量。如上所述，在这种情况下，功率增量可以是通过对储能装置进行控制而产生的功率增量ΔPbat与通过对转子进行控制而产生的功率增量ΔPgen之和。
根据本公开的实施例的风储联合惯量响应方法，优先使用储能装置进行惯量响应而无需转子参与，从而消除了由于转子进行惯量响应而导致的对风力发电机组载荷的冲击。另一方面，当惯量响应需求很大时，可以通过储能装置和转子二者进行惯量响应，提升惯量响应支撑能力。此外，通过在惯量响应过程中使用前馈反馈控制方式对储能装置和转子二者进行控制，既能提高惯量响应的速度，又能保证惯量响应的稳定度。

参照图5，根据本公开的实施例的风储联合惯量响应装置500可包括惯量响应需求功率确定单元501和储能与转子控制单元502。
惯量响应需求功率确定单元501可响应于检测到电网频率发生变化，确定风储联合系统的惯量响应需求功率。如上所述，风储联合系统包括风力发电机组以及连接到风力发电机组的储能装置。惯量响应需求功率确定单元501可基于电网频率的变化率、电网额定频率、风力发电机组的惯量常数和并网额定功率，确定风储联合系统的惯量响应需求功率。具体地讲，惯量响应需求功率确定单元501可通过如上所述的公式(1)来计算惯量响应需求功率。
储能与转子控制单元502可基于确定的惯量响应需求功率通过前馈反馈控制方式对储能装置和风力发电机组的转子进行控制，以产生功率增量，从而满足所述惯量响应需求功率。具体地讲，储能与转子控制单元502可首先以确定的惯量响应需求功率作为给定值，以风力发电机组的实时上网功率值与确定风储联合系统的惯量响应需求功率时的上网功率值之差作为反馈值，通过比例积分微分运算计算第一控制分量，然后以确定的惯量响应需求功率作为前馈量，并将前馈量与第一控制分量之和计算为储能转子联合控制目标，最后基于计算的储能转子联合控制目标，对储能装置和转子进行控制，以产生功率增量。这里，实时上网功率值可基于风力发电机组的变流器机侧功率和功率增量来确定。
进一步讲，储能与转子控制单元502可响应于计算的储能转子联合控制目标小于等于储能装置所能提供的最大功率增量，基于计算的储能转子联合控制目标仅对储能装置进行控制，以产生功率增量。可选择地，储能与转子控制单元502可响应于计算的储能转子联合控制目标大于储能装置所能提供的最大功率增量且小于等于储能装置所能提供的最大功率增量与转子所能提供的最大功率增量之和，以储能装置所能提供的最大功率增量作为储能装置控制目标对储能装置进行控制，并以储能转子联合控制目标与储能装置所能提供的最大功率增量之差作为转子控制目标对转子进行控制，以产生功率增量。此外，储能与转子控制单元502可响应于计算的储能转子联合控制目标 大于储能装置所能提供的最大功率增量与转子所能提供的最大功率增量之和，以储能装置所能提供的最大功率增量作为储能装置控制目标对储能装置进行控制，并以转子所能提供的最大功率增量作为转子控制目标对转子进行控制，以产生功率增量。
