Impacts of High Renewable Energy Penetration in Low Voltage Distribution Network: A Review

The use of fossil fuels for electricity production is decreasing globally due to the green revolution in the energy industry. By introducing renewable energies (RE) into low voltage distribution networks (LVDN), the conventional power system structure is altered through bidirectional power flow, which turns consumers into prosumers and decentralizes the electricity market by allowing domestic end users to use their own energy as needed and sell excess to energy grids. The prosumer grid, with added grid battery storage technologies in the future, will contribute to virtual power plants (VPP) capable of supporting neighbouring communities as a reliable source during normal demands and in times of emergency backups. Thus, the concentration of research is increasing in the domain of integration of RE in the LVDN structure for a standard flexible operation. In this paper, a brief review is carried out on the effects of integrating renewable energy into low-voltage distribution networks (LVDNs), examining its impacts on stability, protection systems, voltage, and power quality. Additionally, it discusses the conventional control strategies for managing these impacts and discusses their respective advantages and disadvantages. Copyright (c) 2024 The Authors.
