Solar, wind, hydro, and biomass energy sources are clean, sustainable, safe, and ecologically acceptable alternatives to traditional fossil fuels [1][2][3][4]. With the growing intensity of environmental and resource issues, low-cost, robust wind-solar power generation has developed as a comparatively fast-growing new energy power generating technology in the power system. Large power outage will have a great impact on the economy and people's life [5]. However, due to the intermittency and volatility of renewable energy such as wind and solar, it affects the safety of the power supply system and increases the cost of rotating reserve, which brings
