电力系统新增电源规划模型及应用研究

Research on a Supplementary Power Planning Model and Its Application in Power System

摘要: 为了满足新型电力系统下的电力和电量需求增加，在传统补充电源方法基础上，将建设和运行阶段的费用视为一个整体，考虑水、火、风、光等电源综合运行成本费用特性，针对多能互补和机组经济优化组合对减少装机成本和运行费用的影响，以效益最大为目标建立了新型电力系统补充电源优化模型，并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，在基于各类电源资源条件限制给出的有限组补充电源方案中，模型可以更为经济合理地给出优化的推荐方案为方案5，相较于传统模型的净效益提高了7.01亿元，对于新型电力系统下补充电源的策略优选提供了一定的参考。

Abstract: In order to meet the increasing demand for electricity and power in the new power system, on the basis of traditional supplementary power supply methods, the construction and operation costs are regarded as a whole. The comprehensive operating cost characteristics of various power sources such as water, fire, wind, and solar are considered. Aimed at reducing installation costs and operating expenses through the syner-gy of multiple energies and optimized unit combinations, a new power system supplementary power op-timization model is established with the goal of maximizing benefits, and a solution method based on dy-namic programming is provided. The case analysis results applied to a certain regional power system show that among the limited group of supplementary power supply schemes based on various types of power resource constraints, the model can more economically and reasonably provide the optimized recommended scheme, which is scheme 5. Compared with the traditional model, the net benefits have in-creased by 701 million Yuan. This provides a certain reference for the strategic optimization of supple-mentary power supply in the new power system.
