摘要：
The uncertainty of runoff and price are the main problems faced by cascade hydropower stations to participate in the power market. Medium and long term timeshare signing of contract electricity price increases the uncertainty of price and the complexity of subsection. Therefore, how to evaluate the risk of piecewise price uncertainty, determine the hydropower enterprises bidding strategy is to be solved urgently. In this paper, based on the transaction rules of Yunnan power market, a medium term section robust optimal scheduling method of cascade hydropower stations considering timeshare contract is proposed. First, a monthly time-sharing optimal operation model for cascade hydropower stations is established based on the settlement rules of contract for difference, and the basic revenue and daily electricity quantity are determined. Then, based on information gaps decision theory (IGDT) segmented price segmented robust model is established, the segmented robust optimization is carried out for each segment of the electricity price, with the goal of maximizing the sum of segmented electricity price fluctuation amplitude, solving the model and risk analysis. Finally, a case study of hydropower stations in the downstream of the Lancang River is carried out to verify the effectiveness of the proposed method. © 2023 Chinese Society for Electrical Engineering.
