摘要/Abstract

摘要： 在系统安全运行的基础上,针对线路网损大、发电成本高的问题,只通过其中某个指标进行发电调度是不合理的,提出了配合无功优化的经济调度以及线性化后机组组合模型,采用理想点法将结合线路网损以及发电成本的多目标优化问题转化为单目标优化问题,利用GAMS进行优化求解。在IEEE-39节点系统以及华东某地区电网上进行算例分析,通过调节机组有功、无功出力以及向节点注入适当的无功功率的方式能够有效降低线损和发电成本。

关键词: GAMS, 无功补偿, 经济调度, 机组组合

Abstract: Based on the safe operation of the electric system, aiming at the problems of large power loss and high generation cost, it is unreasonable to schedule electricity through only one index, so a combined model of economic dispatch with reactive power optimization and a linearized model of unit commitment are proposed. The ideal point method changes multi-objective optimization problem which is combined with the generation cost and power loss into a single objective optimization problem and solved by GAMS. The case analysis for IEEE-39 bus system and a regional transmission network, by adjusting the generator active and reactive power and the reactive power compensation, demonstrate the effectiveness of reducing the power loss and the generation cost.

Key words: GAMS, reactive power compensation, economic dispatch, unit commitment
