考虑风电场并网的电力系统优化调度研究

本文建立了考虑风电场并网电力系统优化调度模型,目标包括运行风险、燃料成本和污染排放量三个目标,约束条件包括电力电量平衡约束、火电机组有功出力约束、火电机组出力爬坡约束、线路传输容量约束,采用直流潮流计算方法对线路潮流进行计算,采用蒙特卡洛法对模型随机变量进行处理。最后,基于粒子群算法对含风电场的IEEE 30节点标准系统算例进行了仿真建模求解。

Multi-objective Dispatch in Wind Power Integrated System

A modeling for multi-objective optimized dispatch in wind power integrated system is established, whose goal is to control operational risks, fuel costs and pollution emission. The constraint conditions include real power operation limits, real power balance constraints, generating unit ramp rate limits and line capacity constraint. DC power flow method is used to calculate the transmission line flow, Monte-Carlo method is introduced to deal with the random variables. At last, the model is solved using PSO.
