The wind-solar hybrid power generation system can operate in the following three modes depending on the changes in wind energy and solar radiation: the wind unit powers the load alone; the photovoltaic energy production system alone supplies the load. ; wind power generation The unit and the photovoltaic power generation system jointly power the load.
Wind-solar hybrid power generation has the following advantages over wind power generation or photovoltaic power generation alone:
●Using the complementarity of wind power and solar power, relatively stable output can be achieved, and the system has higher stability and reliability performance;
● While ensuring the same power supply, the capacity of the energy storage battery can be significantly reduced [5]; > ●GrThrough reasonable design and adaptation, it can essentially be powered by wind and solar hybrid power generation systems, with little or no need to activate backup power sources such as diesel generator sets, etc., which can generate better social and economic benefits. .
