Large-Scale outer hydropower integration into east China Grid: Problems and Solutions
East China Grid (ECG) is the main hydropower receiver of the West-East power transmission channel in China.It has experienced a rapidly increasing scale of hydropower integration in the past decade.Currently, the large-scale outer hydropower is one of important power sources for ECG.However, integrating rapidly increasing outer hydropower into the power grid is suffering from a series of serious problems.Therefore, this study takes into account the load demands and hydropower transmission characteristics to analyze several major problems and find solutions for solving them.The power supply-demand balance problem, hydropower transmission schedule problem, and peak-shaving problem are considered in this study.Correspondingly, three solutions are suggested, including the coordination between the outer hydropower and local power sources, inter-provincial power complementary operation, and introducing market mechanism.This study will be helpful for ECG to effectively receive more and more outer hydropower in the future.
