The wind-solar hybrid power generation system can operate in the following three modes according to changes in wind power and solar radiation: the wind turbine unit supplies power to the load alone; the photovoltaic power generation system supplies power to the load alone; wind power generation The unit and photovoltaic power generation system jointly supply power to 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 energy and solar energy, relatively stable output can be obtained, and the system has higher stability performance and reliability;
●While ensuring the same power supply, the capacity of the energy storage battery can be greatly reduced [5];
●Through reasonable design and matching, it can basically It is 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 achieve better social and economic benefits.
Power generation methods include: thermal power generation, hydropower generation, nuclear power generation, wind power generation, geothermal power generation, etc.
Power generation refers to the production process of using power generation devices to convert raw energy such as water energy, thermal energy of petrochemical fuels (coal, oil, natural gas), nuclear energy, etc. into electrical energy.
Power generation is used to supply the needs of various departments of the national economy and people’s lives.
Nowadays, fossil fuels are still used as the main form of power generation, but fossil fuel resources are not many and are becoming increasingly depleted. Human beings have gradually begun to use solar energy, wind energy, geothermal energy, ocean energy and other energy sources to generate electricity. Generate electricity.
