Based on the characteristics of source load and light storage, the multi-micro grid system engineering design of residential area

为了提高发电接入和用户用电高效可靠性,提出了一种基于源荷和光储特征的小区多微电网系统工程设计。根据具体特征确定小区型多微网的设计目标并设置通用的多微网设计流程,并开展工程实例分析。研究结果得到:南区户子微网2的日光伏出力与负荷关系曲线,通过理论计算可知应配置50 kWh的储能。日光伏出力随时间的变化和日负荷表现出相反的变化规律,日光伏出力在中午达到最大值。南区户子微网2的光储配置明显高于南区家庭型子微网1和北区照明子微网3,经实际调查南区户是居民集中区,人口较为密集,这验证了算法结果的准确性。

In order to improve the access of power generation and the high efficiency and reliability of customer′s electricity consumption, a multi-micro grid system design based on the characteristics of source load and light storage is proposed. According to the specific characteristics, the design target of cell type multi-micro network is determined and the general multi-micro network design process is set up.The research results are as follows: according to the relationship curve between daily photovoltaic output and load of household micro grid 2 in south district, 50 kWh energy storage should be configured through theoretical calculation.The daily pv output changes with time and the daily load shows an opposite change rule, and the daily pv output reaches the maximum value at noon.The optical storage configuration of household micro grid 2 in south district is significantly higher than that of household micro grid 1 in south district and lighting micro grid 3 in north district. According to the actual investigation, households in south district are concentrated areas with relatively dense population, which verifies the accuracy of the algorithm results.
