Abstract

The invention relates to a power system economic dispatching technology, and particularly relates to a unit combination optimization method considering nuclear power peak regulation and security constraints thereof. The unit combination optimization method comprises the following steps of: S1, according to fuel cost, start-up and shutdown cost and peak regulation cost of different types of units in a power system, proposing a power system unit combination optimization target function considering nuclear power peak regulation; S2, proposing a power system unit combination constraint condition considering nuclear power peak regulation; S3, according to the target function in the step S1 and the constraint condition in the step S2, establishing a power system unit combination optimization model considering nuclear power peak regulation and carrying out solving to obtain a unit combination scheme. The optimization method comprehensively considers the security constraints of the nuclear power peak regulation, and can scientifically and reasonably arrange a power system day-ahead dispatching plan so as to meet the power grid load peak valley change requirement.

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...
