Review of Multi-energy Complementary Systems and Trading Strategies Based on Hydropower Regulation
To achieve the carbon peaking and carbon neutrality goals,it is particularly critical to utilize renewable resources such as hydro,wind and solar to address the consumption problem in new energy generation.This paper focuses on the challenges of grid integration of renewable energy sources such as wind and photovoltaic,in particular their intermittency and lack of controllability,hence underscoring the pivotal role of hydropower in mitigating these issues.Through proposing the concepts of hydro-photovoltaic(WPV)and hydro-wind(WW)systems,we highlight the importance of hydropower in balancing renewable energy generation and improving overall energy efficiency.In addition,we investigated a variety of optimization models and trading strategies in depth,offering new insights into the operation of hydro-wind-solar complementary system.
