基于STATCOM/BESS提高风机虚拟惯性自适应协同控制策略
Improving Fan Virtual Inertia Adaptive Cooperative Control Strategy Based on STATCOM/BESS
摘要
Abstract
In order to eliminate the problem of low inertia and large frequency fluctuation in wind power grid-connected system when power disturbance occurs,an improved virtual inertia control strategy was proposed.A cooperative control strategy of adaptive moment of inertia and damping coefficient was introduced in the main control system of wind power inverter.The energy storage static synchronous compensator(STATCOM/BESS)was used to provide the active power and reactive power required by the system.At the same time,the power output of STATCOM/BESS was adjusted according to the frequency deviation and change rate of the system.By analyzing the small signal model of virtual synchronous generator(VSG)of the fan,the setting rules of the adaptive VSG moment of inertia and damping coefficient were determined.The Matlab/Simulink simulation results show that the strategy has a more obvious effect on frequency fluctuation,and can effectively suppress the voltage drop of the fan junction point,and improve the ability of safe and stable operation of the system.关键词
