Optimization Model for Hydropower Boundary Conditions for Minimizing Abandoned Water Volume

A scheduling optimization model for medium and long-term hydropower generation is presented in this paper, Aiming at the complex nonlinear constraints faced by hydropower participation in spot market, the subjective setting of ahead-day spot market boundary, and the decoupling from the medium and long-term scheduling plan. Based on the operating mechanism of ahead-day spot market, this paper decouples multiple nonlinear constraints of hydropower from the clearing model of spot market by setting boundary conditions for spot market of hydropower. Based on the interval prediction values of daily operating boundary conditions such as daily inflow and daily load, and from the perspectives of hydropower and scheduling, a boundary optimization model for the hydropower spot market was constructed with the objective functions of maximizing power generation efficiency and minimizing abandoned water volume, forming the initial boundary for hydropower participation in spot market.
