Capacity Optimization Configuration of Hydro-wind-solar-pumped Storage Complementary System for Market-oriented Consumption
The integrated utilization of hydro,wind and solar resources is one of the crucial directions for future energy development.However,the construction of hydro,wind and solar multi-energy complementary integration is accompanied by many challenges such as substantial investment requirements,coordination difficulties,and disparities between resource distribution and grid demand.Pumped storage emerges as the most economical,efficient and well developed solution at present.Its integration with hydro,wind and solar power promotes widespread clean energy consumption while ensuring grid stability.We insvestigate into the operational characteristics and model simplification methods of multi-energy complementary systems integrating hydro,wind and solar resources.On this basis we develop an evaluation system for comprehensive fixed/variable-speed pumped storage plant to delineate the interplay among different energy components.To foster enthusiasm for multi-clean energy integration,we advocate for the development of rational mechanisms.We also examine the capacity allocation within the multi-energy complementary system,and propose an approach for the joint optimal scheduling of hydro-wind-solar storage.
