Unit combination optimization method considering electric quantity execution and peak regulation matching and controller

Abstract

The invention relates to a unit commitment optimization method considering electric quantity execution and peak regulation matching and a controller. The unit commitment optimization method comprises the following steps: constructing a peak regulation resource matching degree optimization target; constructing a first-stage operation constraint condition; carrying out first-stage modeling and solving; constructing an expected transaction electric quantity plan execution risk optimization target; constructing a second-stage operation constraint condition; and in the second stage, modeling and solving being carried out to determine an electric quantity plan of the generator set. According to the method, the problems of guaranteeing transaction electric quantity plan execution and promoting clean energy consumption needing to be considered in unit combination optimization are converted into two optimization objectives of peak regulation matching and expected execution risk, a two-layer optimization model is constructed, the first layer takes the highest peak regulation matching as the optimization objective, the feasibility of transaction electric quantity execution is comprehensively considered, and the optimization efficiency of the unit combination optimization is improved; and the second layer takes an expected execution risk as a target, and an optimal electric quantity plan is obtained through optimization in a given starting and stopping mode. The method is high in calculation speed and can meet actual operation requirements.
