Modern power systems are undergoing a rapid transition due to the increase in intermittent nonsynchronous renewable generation and distributed energy resources. China's wind and solar energy capacity accounted for 26.7% of the total power generation capacity at the end of 2021. In terms of electricity generation, wind and solar energy contributed 11.8% to the total electricity use in that year. The transition poses challenges for system operators in accurately and comprehensively assessing the actual status of power systems.
Modern power systems are witnessing a rapid transition with the increasing penetration of intermittent nonsynchronous renewable generation and distributed energy resources. According to the National Energy Administration, China's installed wind and solar energy capacity accounted for 26.7%of the country's total power generation capacity at the end of 2021. In terms of electricity generation, wind and solar energy accounted for 11.8% percent of the total electricity use that year. In the renewable energy development plan in the 14th Five-Year Plan (2021-2025), China aims for renewables to meet 33%of national power consumption and for nonhydro renewables to satisfy 18%. This transition poses challenges for system operators to grasp the actual status of power systems accurately and comprehensively.
