In recent years, massive introduction of photovoltaic power sources (PV) has compounded the problem of voltage fluctuation in distribution networks. The problem has been recognized from early on, and many research studies have been already reported. However, majority of the previous studies focused on high-voltage distribution networks. Hence, in this study, the authors investigated appropriate configurations for low-voltage distribution networks in Japan to address the problem as a planning problem. The on-site practical measures were examined, and by means of the obtained knowledge, a network configuration problem was formulated for low-voltage networks. In addition, an effective solution method is proposed, based on the priorities of measures applied to the network equipment. Numerical simulations were conducted for verifying the performance of the proposed method, wherein corroborative results were obtained. © 2021 Institute of Electrical Engineers of Japan.

光伏电源高穿透性低压配电网配置研究

近年来，大量引入光伏电源（PV）使配电网电压波动问题更加复杂。这个问题很早就被认识到，并且已经有许多研究报告。然而，以前的大多数研究都集中在高压配电网络上。因此，在本研究中，作者调查了日本低压配电网络的适当配置，以解决作为规划问题的问题。研究了现场的实际措施，并利用所获得的知识，制定了低压电网的网络配置问题。此外，根据应用于网络设备的措施的优先级，提出了一种有效的解决方法。进行了数值模拟以验证所提出方法的性能，其中获得了确凿的结果。© 2021 日本电气工程师学会。由 Wiley Periodicals LLC 出版。
