A Stochastic Programming Based Short-Term Optimization Scheduling Strategy Considering Energy Conservation for Power System Containing Wind Farms
摘要
Abstract
Optimization scheduling strategy considering energy conservation and environment protection for multi source power system containing wind farms, which possesses important economic benefic and social effect, is a novel complex nonlinear problem. Based on traditional hydro-thermal economic scheduling model and emerging thermal-wind complemental economic scheduling model, a stochastic programming based short-term optimization scheduling model for power system consisting of thermal plants, hydropower stations and wind farms is proposed. In the proposed model, the chance constraints are used to describe objective function and constraints, and scheduling schemes under differnet confidence levels are given. Meanwhile three objectives, namely minimum water consumption of hydropower stations, minimum coal consumption of thermal power plants and minimum outflow discharge of nitrogen oxides, are taken into account, then by use of ideal point method, the multi objective problem is turned into single objective problem. In allusion to the randomness of both wind speed and wind farm output, the stochastic simulation is combined with sequential quadratic programming to solve the optimal value of objective function. Case simulation results show that the proposed scheduling strategy is effective and feasible.关键词
