Abstract

The invention discloses a power generation planning method for a power system with a pumped storage power station. The power generation planning method is characterized by comprising the following steps: firstly, making a repairing plan, and acquiring a load curve of the power system; secondly, under constraint conditions of load balance, set stressing and climbing limits, system spinning reserve and pumped storage power station capacity, establishing a model with the minimum sum of the power generating cost and the start-stop cost of all thermal power generating sets within a scheduling period as an objective; finally, solving according to a basic particle swarm algorithm under chaos control. By the power generation planning method, the problems that during calculation of a power generation planning model of the power system, convergence is poor and local optimum easily appears are effectively solved, so that a more reasonable power generation plan of the power system can be made.

Description

technical field [0001] The invention relates to a method for formulating a power system power generation plan, in particular to a method for formulating a power system power generation plan including a pumped storage power station. Background technique [0002] With the increasing size of pumped storage power stations and the implementation of energy conservation and emission reduction policies, the scheduling of traditional pumped storage power stations has gradually exposed the problems of low leanness and long-term dominance of empirical scheduling. At the same time, subjectively, the lack of understanding of "4 kWh for 3 kWh" of pumped storage power stations leads to unfairness in dispatching them. [0003] The power system scheduling model contains many variables and constraints, and it is solved by traditional Lagrangian relaxation method, network flow programming method, dynamic programming method, intelligent-based genetic algorithm, neural network algorithm, etc. T...
