In order to solve the problem that the impedance of each line. . We propose a unique energy storage way that combines the wind, solar and gravity energy storage together. And we establish an optimal capacity configuration model to optimize the capacity of the on-grid wind-photovoltaic-storage hybrid power system. [pdf] Can VSG control a large power fluctuation?. Abstract: In high-penetration renewable-energy grid systems, conventional virtual synchronous generator (VSG) control faces a number of challenges, especially the dificulty of maintaining syn-chronization during grid voltage drops. This dificulty may lead to current overloads and equipment. . In order to maximize the effectiveness of the advantages of the flexible and adjustable parameters of VSG control, an adaptive VSG control strategy considering SOC constraint of the energy storage unit is proposed in this paper. This difficulty may lead to current overloads and equipment disconnections. .
