在全球范围内，分布式发电，即太阳能光伏发电的发展势头强劲。在网络边缘引入发电给网络运营商带来了许多挑战，特别是过电压。在分布式发电的总渗透率较低时，经验法则在一定程度上是有效的。澳大利亚昆士兰州等地区目前有25%的家庭拥有太阳能光伏，需要更有效的方法来确定更准确的“托管容量”。本文使用网络拓扑数据开发具有代表性的低压网络，并推导出DG托管容量，这些容量已被现场数据证实，以确保统计有效性。然而，该分析的一个关键结论是，考虑到观察到的结果差异，典型的LV网络和托管容量可用于广泛的分析，但是网络运营商应考虑对每个新连接进行分析，考虑到单个客户级别的差异。
Globally there has been a strong uptake in distributed generation, namely solar PV. The introduction of generation at the network fringes has introduced a number of challenges for network operators, particularly overvoltage. Rules of thumb have been somewhat effective while the total penetration of distributed generation was low. With regions like Queensland, Australia now having 25% of households with a solar PV, more effective methodologies are required for determining more accurate “hosting capacities”. This paper used network topology data to develop representative LV networks and derive DG hosting capacities that have been confirmed with field data for statistic validity. A key take-away from this analysis however is that given the observed variance in results, typical LV networks and hosting capacities can be used for broad based analysis, however network operators should consider performing analysis for each new connection given the variance at an individual customer level.
