Research on VSG Energy Storage Control Strategy Based on Artificial Fish Algorithm

With the integration of solar energy, wind energy and other new energy into the power system, the stability of the system has been greatly challenged. Virtual synchronization technology is a popular method to solve intermittent and random access of new energy sources. Energy storage device is the important support of virtual synchronization technology. In this paper, a variable coefficient control strategy is proposed for the control of energy storage device in virtual synchronization technology, and an improved artificial fish swarm algorithm is used for optimization. The simulation results show that the algorithm proposed in this paper can better control the output power of the controller in the VSG, and achieve the purpose of correcting the energy storage device.
