Abstract

Economic performances of a microgrid with multi-energy are effected by many factors such as the configuration of microgrid systems for the specific installation sites and cluster of loads, operation modes and dispatching schedules of the microgrid, the electricity market, energy policy and alike. And the configuration of the microgrid is the premise of all factors. This paper presents an optimization model to quantitatively evaluate the economic impacts of different installation sites on microgrids with multi-energy. In this model, optimal configuration schemes for microgrids installed at typical sites are designed by particle swarm optimization method. The economic performances of optimal configuration schemes are evaluated by the operation simulation with the proposed indexes. Those typical installation sites mentioned above belong to different regions which are divided into the five-level classifications in terms of the richness of wind and solar resource and the distributions of loads in China. The calculation results may be used for the decision-making references by the decision-makers.

多能微电网不同地点安装的经济影响定量分析

多能型微电网的经济性能受具体安装地点和负荷集群的微网系统配置、微网运行方式和调度计划、电力市场、能源政策等诸多因素的影响。而微电网的配置是所有因素的前提。本文提出了一个优化模型，用于定量评价不同安装地点对多能微电网的经济影响。在该模型中，采用粒子群优化方法设计了典型站点微电网的最优配置方案。利用所提出的指标，通过运行仿真对各优化配置方案的经济性能进行了评价。上述典型安装地点属于不同的区域，根据中国风能和太阳能资源的丰富程度和负荷分布情况分为五级。计算结果可为决策者提供决策参考。
