Analysis of power grid performance due to PV integration

Power utilities and individual consumers face fascinating challenges as a result of the significant growth in the global penetration of photovoltaics (PV). This includes financial losses that resulted from overvoltage-induced PV curtailment during times of high PV generation. Some of these losses are: In recent years, there has been more interest in the use of rooftop PV systems because they are easy to install and don't take up any outside space. On the other hand, the unfavourable effects that increased PV penetration has on the distribution system are a source of concern. Problems with the voltage quality are being caused in the power network as a result of power loss, reverse power flow (RPF), voltage fluctuations, and voltage unbalance. Alterations in system frequency, power factor, and harmonics, on the other hand, are having an effect on the power quality. An excessive amount of photovoltaic (PV) penetration is not only the underlying cause of voltage stability but also has a negative impact on protection systems. This article's purpose is to conduct an in-depth analysis of the effects that solar PV systems have on distribution networks and to assess the efficacy of various approaches to problem-solving with regard to voltage quality, power quality, system protection, and system stability.
