ABSTRACT：During carrying on the energy-saving and emission-reduction policy, actively studying the mode of energy generation scheduling optimization has been widespread concern on the power department. Hydraulic coupling between hydropower plants, time of delay with downstream flow and possible factors such as wasting water, must take into account in the optimal scheduling of cascade hydropower plants containing hydro and thermal electric plants. Present a multi-objective model considering environment protection and saving energy. This model takes total operation costs of thermal power plants, contaminative gas emission and spilling water of hydroelectric power plants as optimal objectives. Solve this problem with heuristic agent method. The simulation results show that this proposal model increases generation benefits of hydroelectric power plants, reduces operation costs of thermal power plants, advances comprehensive benefits of power systems, and provides a novel research thought for hydrothermal power systems short-term optimal scheduling problems.
