[Abstract]:The microgrid system integrates new energy generation system, energy storage system and local load. It reduces the uncertainty of new energy generation through the mediation of its internal energy storage units, providing adequate clean energy to users and improving the quality of power supply. It is an effective method to solve the problems of dispatching and operation caused by the large area access of distributed new energy generation system. The control research of microgrid system can guarantee the stable operation of microgrid and make it complete the energy interaction with large power grid better. At the same time, the excellent control strategy can make the microgrid and large grid cut off seamlessly, and ensure the sustainability of the important load power supply to the users of microgrid. Based on the analysis of the characteristics of solar power generation system and energy storage system, the steady and transient operation of micro-grid is studied from the microsource level and micro-grid level. The control strategy is put forward according to the construction practice of Liaoning Electric Power Company. Based on the RTDS simulation platform, the photovoltaic generation model, the energy storage system model and the power company microgrid model are built, and the effectiveness of the control strategy is verified theoretically. At the same time, the power company microgrid monitoring system is designed, the control strategy is embedded, and the practicability of the control strategy under various operating conditions is verified by the actual operation.
