Research and design of microgrid system structure based on multi-energy complementary power generation in rural areas

With the development of China's power industry entering a critical period of mode transformation, structure adjustment and power change, the state pays more and more attention to the promotion of new energy microgrid.The development and utilization of abundant wind, hydropower, solar and biomass energy resources in rural areas is an effective way to solve the problem of rapid increase in power consumption in rural areas and power supply in remote mountainous areas.This project analyzes the complementarity of the four renewable energy combined power generation in many aspects, and proposes a new rural "scenery aquatic" multi energy complementary power generation microgrid power supply system.The rural micro grid structure model of the small hydropower and solar photovoltaic power generation system with water storage reservoir is designed, and the scheduling strategies of the two operation modes of the micro grid island and grid connection are analyzed.
