摘要

针对永磁直驱风机与分散式混合储能系统提出了联合无功控制策略。首先对永磁直驱风机以及储能系统的无功调节能力进行分析，确定永磁直驱风机与储能系统通过变流器控制均可参与无功调节；其次提出无功控制策略，从信号接收、初次分配、内部分配等方面进行分析，在初次分配中采用了等裕度分配方法，在内部分配中考虑了以储能优先出力进行比例分配；最后通过仿真验证了该策略的有效性，该策略可充分利用永磁直驱风机与储能系统的无功容量能力对电网的电压提供有效支撑。

Abstract

A combined reactive power control strategy for permanent magnet direct-drive wind turbine and distributed hybrid energy storage system is proposed. Firstly

the reactive power regulation capability of the permanent magnet direct-drive wind turbine and energy storage system is analyzed

and it is determined that both the wind turbine and energy storage system can participate in reactive power regulation through converter control.Secondly

the reactive power control strategy is put forward

which is presented in terms of signal reception

initial allocation

and internal allocation. In initial allocation

the equal margin allocation method is adopted. In internal allocation

the proportional allocation with the priority output of energy storage is considered. Finally

the effectiveness of the strategy is verified by simulation

it shows that the power grid voltage can be supported by fully utilizing the reactive capacity of the wind turbine and energy storage system.
