Control strategy of wind-solar-storage complementary power generation system

With the introduction of ‘dual carbon’ targets, the use and demand for renewable energy sources such as wind power and photovolatics is becoming more and more urgent. However, the output of these natural resources is highly uncertain and significantly affected by external conditions. In this paper, by introducing the wind-solar-storage hybrid power generation system, the advantages of wind, solar and storage technologies are effectively integrated to meet the actual demand, improve the efficiency of energy use, achieve the goal of energy saving and emission reduction, and reduce the dependence on fossil fuels. The control strategy of the wind-solar-storage complementary power generation system is discussed in depth, and the efficient operation and cooperative work of each part of the system is realised. Meanwhile, through theoretical analyses, as well as simulation experimental studies, the mechanism and law of the impact of the wind-solar-storage complementary power generation system on the distribution network after grid connection are revealed.
