Recently, power systems have witnessed a vast shift toward the integration of distributed generation systems (DGs), such as solar photovoltaic (PV) systems. The importance of planning DGs cannot be denied as they help to improve operations in the system and reduce the reliance on fossil fuel-based power generation methods. This paper proposes a new method for site and size selection of distributed PV systems considering system active power loss and nodal voltage profiles. The novelty of this work relies on nodal voltage magnitude deviations for PV siting and sizing criteria where PV DG sizes are weighted based on the voltage deviation index. This work includes a detailed case study performed on the Northern Cypriot power system with promising results that validate the proposed method against unweighted approaches.

最近，电力系统见证了向分布式发电系统 (DG) 集成的巨大转变，例如太阳能光伏 (PV) 系统。不可否认规划 DG 的重要性，因为它们有助于改善系统运行并减少对基于化石燃料的发电方法的依赖。本文提出了一种考虑系统有功功率损耗和节点电压分布的分布式光伏系统选址和规模选择的新方法。这项工作的新颖性依赖于 PV 选址和尺寸标准的节点电压幅度偏差，其中 PV DG 尺寸根据电压偏差指数加权。这项工作包括对北塞浦路斯电力系统进行的详细案例研究，结果很有希望，验证了所提出的方法与未加权方法的对比。
