住宅光伏（PV）面板的渗透率正在不断增加，特别是在那些有特殊激励措施的国家。自 2010 年推出上网电价补贴计划以来，英国的光伏总装机容量已从微不足道的增加到 1.2 吉瓦。因此，配电网络运营商 (DNO) 已经在低压 (LV) 馈线出现了集群出现的电压问题。这项工作提出了一种基于蒙特卡罗的技术来评估不同光伏渗透率对低压网络的影响，以估计其相应的托管能力。研究了英格兰西北部两个真实低压网络的三相模型，考虑了国内负荷和光伏发电的 5 分钟分辨率合成数据。与电压相关的影响使用欧洲标准 EN50160 进行测量。此外，还分析了数据粒度对影响评估的重要性。低压网络的研究结果表明，长度较长、客户数量较多的馈线往往会遇到光伏渗透率较低的电压问题。就粒度而言，我们发现每小时分辨率分析低估了住宅光伏的电压影响。
The penetration of residential photovoltaic (PV) panels is increasing particularly in those countries with special incentives. The total PV installed capacity in the UK has increased from negligible to 1.2 GW since the Feed-In Tariff scheme was created in 2010. As a result, Distribution Network Operators (DNOs) are already experiencing voltage issues in low voltage (LV) feeders were clusters have appeared. This work proposes a Monte Carlo-based technique to assess the impacts of different PV penetrations on LV networks in order to estimate their corresponding hosting capabilities. Three-phase models of two real LV networks in the North West of England are studied considering 5-min resolution synthetic data for domestic load and PV generation. Voltage-related impacts are measured using the European Standard EN50160. Additionally, the importance of data granularity on the impact assessment is analyzed. Results for the studied LV networks indicate that feeders with greater lengths and larger number of customers tend to experience voltage issues with lower PV penetration levels. In terms of the granularity, it was found that hourly resolution analyses underestimate the voltage impacts of residential PV.
