Review on high penetration of rooftop solar energy with secondary distribution networks using smart inverter

Abstract

The key downsides of rooftop solar photovoltaic energy systems in comparison to other renewable energy systems their impacts and distinct operating characteristics of rooftop solar PVs in the distribution system with low power utility networks, are investigated in different directions. Global researchers and operation engineers examined harmonic distortion, active and reactive voltage control, voltage drop control, and radial, mesh power flow control analysis in distributed systems are reviewed in this study. The efficacy of a secondary distribution network system connected to the grid with smart inverters in terms of implementing high penetration of rooftop solar energy with a secondary distribution network system utilizing smart inverters was examined in this review study. This study examines a total of 42 relevant studies on the various stages of optimization between 2014 and 2021, a rooftop solar PV system was installed. The performance of an efficient secondary distribution system with grid integrated smart inverter; and (ii) Algorithms based on optimization for addressing the objectives in rooftop solar PV systems are examined in this research.
