Abstract

According to the electrical model and mechanical model of synchronous generator, the control model of virtual synchronous generator is deduced, and the relationship between control parameters and virtual synchronous generator is analyzed. Based on the power electronics technology, the energy storage power control strategy is given, including the virtual synchronous generator power control loop and the voltage and current double loop control strategy. Combined with the actual operating conditions of energy storage power conversion system, an adaptive adjustment method of virtual synchronous generator parameters is proposed, and the simulation model is built, and the effectiveness of the adaptive parameter control strategy of virtual synchronous generator is verified by simulation analysis.
