考虑风电接入的电力系统动态随机环境/经济调度

Dynamic and Stochastic Environmental Economic Dispatch for Power Systems Integrated with Large-Scale Wind Power

考虑风电固有的随机性、波动性和间歇性,兼顾环境污染和经济性的多优化目标,针对不同时间断面,构建风电接入后的电力系统动态随机环境/经济调度模型。引入机会约束规划理论,设计基于非劣排序的随机多目标粒子群优化算法,应用模糊集合理论和熵权法建立综合最优解的提取方法。算例分析验证了该模型和算法的可行性和有效性。

Giving consideration to the randomness,volatility and intermittent,multi-optimization objective of environmental pollution andeconomy,and aiming at fracture surface at different time,this paper established a dynamic and stochastic environmental economic dispatchmodel for power system integrated with large-scale wind power.The chance constraint planning theory was introduced.This paper designeda superior multi-objective particle swarm optimization algorithm based on Pareto non-dominated sorting mechanism and used the fuzzy settheory and entropy weights to extract the comprehensive optimal solution.The calculated example analysis verifies the feasibility and validityof this model and its algorithm.
