The invention discloses a method for calculating a multi-objective energy storage scheduling diagram of a large-scale mixed reservoir group. The upper and lower limits of the water level, output and flow constraints of the period of time operation; the guaranteed output and the minimum discharge flow are separately discrete; for each group of discrete values of the guaranteed output and the minimum discharge flow, a hybrid reservoir group energy storage scheduling diagram is constructed; for each The energy storage scheduling diagram of the mixed reservoir group is simulated and calculated; for each minimum discharge flow, a multi-objective solution space is constructed, and the optimal scheduling scheme for each minimum discharge flow is obtained according to the scheme optimization criterion or the actual scheduling criterion. The invention improves the original discriminant coefficient, water volume balance equation and energy storage calculation formula, solves the complex water volume and water head connection problem in the drawing of the energy storage dispatching diagram of the mixed reservoir group; simultaneously realizes the energy storage dispatching diagram and multi-objective Scheduling coupling.
Description
technical field [0001] The invention belongs to the field of optimal operation of hydropower energy and optimal scheduling of electric power system power generation, and more specifically relates to a method for calculating a multi-objective energy storage scheduling diagram of a large-scale mixed-connected reservoir group. Background technique [0002] As a conventional joint scheduling tool for reservoir groups, the energy storage dispatching chart has been widely used in the joint dispatching of reservoir groups because of its clear physical meaning. For the reservoir energy storage scheduling diagram, there are no relevant research results for large-scale mixed reservoir groups with both series reservoirs and parallel reservoirs. In addition, unlike single-reservoir scheduling with simple variables and single goals, mixed-connected reservoirs composed of multiple reservoirs need to implement unified scheduling and unified management, which often has the characteristics o...
