摘要：
In order to solve the problem that the grid-connected active power of energy storage virtual synchronous generator（VSG） is difficult to take into account the good dynamic characteristics and steady-state performance under the disturbances of active power command and power grid frequency，a grid-connected active power response optimization control strategy of active power fractional differential correction-based VSG（AFDC-VSG） is proposed. The grid-connected active power closed-loop small-signal models of typical VSG and AFDC-VSG control strategies are established respectively，and the corresponding parameter design processes are given. MATLAB／Simulink simulation software is used to compare and analyze the grid-connected active power response characteristics of energy storage VSG by using different control strategies under two types of disturbance，and the experimental platform of energy storage VSG grid-connected system is established. Simulative and experimental results jointly verify the effectiveness and superiority of the proposed AFDC-VSG strategy in optimizing the grid-connected active power response performance for energy storage VSG. © 2024 Electric Power Automation Equipment Press.
