Key Technologies for Hydro-wind-solar Multi-energy Complementary Operation:Research Status and Prospect
In the background of global energy structural transformation,the hydro-wind-solar multi-energy complementary system,as an essential part of modern energy systems,is receiving increasing attentions.In this paper we examine the distribution of water and wind resources in China and analyze the construction planning for complementary bases.We further scrutinize the technological challenges encountered in critical stages of the hydro-wind-solar multi-energy complementary systems.These challenges include resource assessment and system integration during planning,forecasting and dispatching and efficient operation in operation period,and power trading and marketing during consumption.Additionally,we summarize the latest research progresses in resource assessment methods,system integration and optimization,intelligent dispatch system development,and energy storage technology application.Finally,we offer insights into future research trends.This work serves as an important reference for both research and practical applications in related fields.
