Long-term Optimal Dispatch of Hydropower Stations with Optimization Algorithms

Long-term optimal dispatch for hydropower stations aims to maximize total power generation over the scheduling period by rationally allocating monthly power discharge flows, while satisfying power system output requirements and downstream comprehensive water usage demands. This involves optimizing water resource utilization under given conditions including forecasted inflow hydrographs, downstream water demand curves, initial and terminal reservoir water levels. The implementation typically employs optimization algorithms like dynamic programming or genetic algorithms to solve the constrained maximization problem, where objective functions calculate energy output based on hydraulic relationships and system constraints.
