摘要: 含可再生能源的独立微电网为解决无电地区用电提供了一种因地制宜的可持续的电力解决方案,但目前微电网由于理论性强、可操作性差,市场推广困难。为了解决目前微电网项目开展的壁垒,提出了一种关于独立水光储微电网系统的简化设计。根据项目所在地的微电源与负荷特性,计算系统的需电量,得出光伏及水电等电源所需的配置容量。为合理地协调各个时段微电网系统内各电源的出力来满足各时段负荷的需求,确保微电网内各电源模块出力与负荷需求的实时功率平衡,最大程度保障系统供电可靠性,本文提出了系统的两个重点考核指标——系统缺电率及能量溢出比,根据这两个指标,确定微电网系统的电池储能系统的配置容量。本文总结了一套合理的关于微电网的通用初步设计方法,为从事微电网的工程设计人员提供了便利。

Abstract: Independent microgrid with renewable energy is a suitable and sustainable solution to provide electricity power in areas without electricity. Nowadays microgrid with strong theory still has difficulties to be spread because of the poor operability. In order to solve the barrier of the current microgrid project, this paper proposed a simplified design of an independent hydropower-photovoltaic energy storage microgrid system. According micro sources and load characteristics of the project location, calculating the system power demand is required to get the configuration capacity of photovoltaic、hydropower and other power sources. For maximum the reliability of power system supply, this paper brings forward two key appraisal indicator of the system:the power system shortage rate and energy leakage ratio in order to reasonably coordinate each output of power sources in microgrid system to meet the load requirements in each time period and to ensure the real-time power balance between the load requirements and the output of each power source module in the microgrid. The configuration capacity of the battery storage system in the microgrid system can be calculated based on these two indicators. This article summarizes a set of general design methods for microgrid which provides convenience for engineering designers that engaged in microgrid field.
