The invention discloses a power system dispatching optimization method and a device. By defining a preset multi-objective optimization model, and based on NSGA- II algorithm, a first objective function and a second objective function are optimized in a multi-objective optimization model to obtain a Pareto optimal solution set satisfying a constraint condition in the multi-objective optimization model, and the Pareto optimal solution set comprises a non-inferior solution in the first objective function and the second objective function. The NSGA-II algorithm is used for multi-objective optimization of power system dispatching. On solving the problem of multi-objective optimization, the Pareto optimal solution set satisfying the constraint conditions in the multi-objective optimization modelis determineded, that is, the non-inferior solution in the process of multi-objective optimization is selected to obtain the compromise optimal solution of the optimization multi-objective. To achieve the goal of economic environment optimal dispatch of power system without sacrificing other objectives as a cost, the current multi-objective optimization needs to be completed.
Description
technical field [0001] The invention relates to the field of energy technology, in particular to a power system scheduling optimization method and device. Background technique [0002] The power system is a complex system including power supply, power transmission, power transformation, power distribution, and power supply network. The optimal dispatch of the power system generally refers to economic dispatch, that is, on the basis of considering the economic characteristics and operating constraints of the generator set, the optimal dispatch A power generation plan that makes the system meet the operating requirements and has the lowest operating cost. At present, thermal power coal-fired generating units are the main force of electric power production, and the emission of polluting gases has increasingly become the focus of people's attention. [0003] In the prior art, the environmental economic dispatch optimization is carried out for the power system of thermal power c...
