Scheduling Optimization Model for Medium and Long-Term Hydropower Generation

An optimization strategy for ahead-day spot market boundary of hydropower considering the connection with the medium and long-term hydropower scheduling plan is proposed to promote hydropower participation in spot market trading and large-scale consumption. In order to effectively connect the results of multi time scale hydropower optimization scheduling and further promote hydropower participation in spot market trading, a multi-objective optimization method is used to decompose the hydropower medium and long-term scheduling plan into various time periods before the day, and the boundary model of the hydropower ahead-day spot market s introduced using intersecting method for the set to correct the boundary range. A multi scenario comparative analysis method is used to verify the effectiveness and rationality of the proposed optimization strategy.
