摘要
为了解决电力系统电源短缺情况下的电源规划优选问题,在考虑机组优化组合经济运行特性、多电源之间的互补特性、电价的波动特性的基础上,将建设、运行阶段的费用和效益视为一个整体,以总成本费用最小和运行效益最大为目标建立了考虑电力系统特性的补充电源多因素多目标优化模型,并采用约束法将多目标问题转化为单目标问题,给出了基于动态规划的求解方法.应用于某区域电力系统的算例分析结果表明,在不考虑各类电源资源条件限制的情况下,模型可以更为经济合理地给出在有限组补充电源方案中的优化推荐方案,对于电力系统中补充电源的策略优选提供了一定的参考.
Abstract
In order to address the power supply planning optimization issues during power shortages in power systems,considering the eco-nomic operation characteristics of the optimal combination of units,the complementary characteristics between multiple power sources,and the fluctuating nature of electricity prices,a multi-factor and multi-objective optimization model for supplementary power sources,which takes into account the characteristics of power systems,is established with the objectives of minimizing the total cost and maximizing the op-erational efficiency.By treating the costs and benefits of the construction and operation phases as a whole,and using constraint methods to transform the multi-objective problem into a single-objective problem,a solution method based on dynamic programming is provided.The re-sults of the case analysis applied to a regional power system demonstrate that,without considering the constraints of various power resource conditions,the model can more economically and rationally provide an optimized recommendation scheme among a finite set of supplementa-ry power supply options,offering a certain reference for the strategic optimization selection of supplementary power sources in power systems.
