Abstract

The present invention relates to power system economic scheduling technology, in particular to a unit combination optimization method considering nuclear power peak regulation and safety constraints, including the following steps: Step 1, according to the fuel cost, start-stop cost and adjustment Peak cost, put forward the optimization objective function of power system unit combination considering nuclear power peak shaving; step 2, propose power system unit combination constraint conditions considering nuclear power peak shaving; step 3, based on the objective function described in step 1 and the constraint conditions described in step 2 , establish and solve the power system unit combination optimization model considering nuclear power peak shaving, and obtain the unit combination scheme. This optimization method comprehensively considers the safety constraints of nuclear power peak regulation, and can scientifically and reasonably arrange the day-ahead dispatching plan of the power system to meet the demand for peak and valley load changes in the power grid.

Description

technical field [0001] The invention belongs to the technical field of electric power system economic dispatching, and in particular relates to a unit combination optimization method considering nuclear power peak regulation and safety constraints. Background technique [0002] At present, the load peak-to-valley difference in my country's coastal areas continues to increase. With the large-scale grid connection of nuclear power and wind power in the future, the peak-shaving situation of the power system is becoming more and more unoptimistic, and the demand for nuclear power units to participate in peak-shaving is increasing day by day. Although modern nuclear power units are designed with peak-shaving capability, there are few examples of nuclear power unit peak-shaving in my country, and in the field of power system unit combination research, the mathematical modeling of nuclear power peak-shaving and its safety constraints has not been carried out in depth. Therefore, it...
