| 摘 要： | 为克服传统经济调度的目标单一,计算量大,优化不力等诸多不足导致模型适用的困难,从电网分区和协调计算的角度建立了基于多目标优化的分布式电网经济调度模型.该模型同时考虑了由售购电价差引起的经济效益最大,机组运行能耗最少和污染气体排放最小等三个目标函数.重点阐述了一种基于近似牛顿方向的多区域分布式计算方法,并利用改进的距离差分进化算法用于各个分区内的独立优化计算,然后采取异步迭代的信息同步机制实现了全局的等值修正计算.最终算例表明了该方法能够在分布式电网经济调度的优化计算过程中取得良好的应用效果.

| Abstract: | Traditional economic dispatch model has single target,large amount of calculation,optimization ineffective and many other defects.On the point of the subarea division and coordinated calculation view,a distributed economic dispatch model of power grids based on multi-objective optimization is established in this paper.It has three objective functions and takes into account the maximum benefits that brought from the difference of sale and purchase price,both the minimums of generation costs and pollution emi... |
