Research on clearance model for electricity market with cascade hydropower stations

Abstract

Together with power structural reform, the intended contribution target of carbon neutral and carbon peaking aims to promote the market-based consumption of renewable energy, which has become an essential task for the construction of China’s power market. Cascade hydropower is a special form of hydro-generation, the upstream and downstream power stations have a close hydraulic coupling relationship with each other. In order to ensure the fair participation of all generation entities in the market and improve the feasibility of the transaction results, the operational characteristics of the cascade hydropower should be integrated into the market clearance model. In this paper, a day-ahead market case including six generation entities is designed, and the rationality and practicality of the clearance model are verified by analyzing the results of market transaction in different operation scenarios.
