摘要
随着电网规模的扩大,电网计算优化问题中计算时间长、收敛速度慢等问题变得严重。针对此问题,该文利用基于电网分区和辅助问题原理APP(Auxiliary Prob lem Princ ip le)的分布式并行优化模型来解决多区域有功负荷的经济调度,并且把各个区域内的虚拟发电机看成真实发电机,推导出其耗量特性曲线。仿真结果表明,本方法具有较强的收敛性和快速性。
Along with the enlarging of electric network,the problem which long-time computing and slow rapidity of convergence become serious in the electric network computing. To handle this problem, this paper utilizes distributed parallel optimization model which based on subarea division and auxiliary problem principle（APP） to solve muhiregion field active load in economic dispatch. It takes the virtual generator as real generator to deduce its rate of consumption characteristic. Simulation shows that this means is fast and has a good convergence property.
