Abstract :
As the renewable energy scale increases rapidly, evaluation of intermittent energy capacity credit (IECC) is becoming one of the hottest issues in power system planning. Ignoring IECC will lead to serious waste; however, high expectations of IECC will bring risk to the reliability of power system. In order to evaluate IECC accurately, firstly, uncertainly factors on IECC are analyzed from multiple angles, and the main assessment process of IECC is presented. Based on the various IECC calculation methods of single intermittent energy, the adaptive methods of wide-scale multiple intermittent energy are put forward. Finally, improvement measures of capacity credit are advanced from aspects of multiple energy output correlation, power grid side, demand side, and energy storage. The research hotspots and developing directions are discussed.
