Abstract

A microgrid integrates multi-energy distributed generation, cooling-heating-power demand and energy storage to provide an effective solution for power supplies to remote and islanded areas. The microgrid planning should consider both technical and economic aspects based on local demand and resources condition, as well as the network structure and operating strategy of the microgrid. This paper introduces an industrial solution on integrated resource planning for microgrids, which applies the software ‘Capacity Expansion’ and ‘Portfolio Optimization’ to optimize the composition and capacity of renewable generations and battery storage, as well as to produce the operational and economic results in a long-term horizon. A case study is performed using the proposed solution based on an actual microgrid project in China. The results provide recommendations on microgrid’s generation capacity expansion, optimal sizing for battery storage, operating constraints on energy exchange with upper main grid, and electricity bill contract design.

中国多能微电网案例可行性评价

微电网集成了多能分布式发电、冷热电需求和储能，为偏远和孤岛地区的电力供应提供了有效的解决方案。微网规划应根据当地的需求和资源条件，以及微网的网络结构和运行策略，从技术和经济两个方面进行考虑。本文介绍了一种微电网综合资源规划的工业解决方案，该方案应用“容量扩展”和“投资组合优化”软件来优化可再生能源发电机组和电池储能的组成和容量，并产生长期的运营和经济效益。并以中国某实际微电网项目为例进行了案例分析。研究结果为微电网的发电容量扩展、电池储能的最优规模、与上主电网能量交换的运行约束以及电费合同设计提供了建议。
