ABSTRACT

In order to meet the requirements of rapid load change for coal-fired power plants under the situation of new energy power system, this paper studies the problem of rapid plant level load optimal distribution considering the start-up and shutdown section of coal mills. Firstly, a mathematical model of rapid plant level load optimal distribution considering the start-up and shutdown interval of the coal mill is constructed. Taking the start-up and shutdown interval of the coal mill as a constraint condition, the non operational region processing strategy is used for pretreatment, and the improved genetic tabu algorithm is used to find the optimal solution of the objective function. The simulation results show that the distribution results obtained by taking rapidity as the goal and economy as the goal are significantly different. The load adjustment time with rapidity as the goal is significantly shorter than that with economy as the goal. The effectiveness of the model and algorithm is illustrated, and it is verified that the plant level load optimal allocation with the goal of rapidity is an effective control strategy for the rapid load change of units, which can contribute to further improving the flexible operation capacity of coal-fired units under the situation of new energy power system.
