The role of hosting capacity study in power system advancements: a review (2301.04765v1)

Abstract: The fast depletion of conventional energy sources due to increased energy demands and environmental concern has motivated power utilities to integrate more renewable energy sources into their power systems. Due to the intermittent nature and low or non-existent inertial response of these sources, a high penetration of RESs can lead to various issues in the operation of power systems such as oscillations in power system voltage and frequency, increased harmonic distortion, failure of protective equipment, overloading of transformers and feeders, and increased line losses. Such problems arise when the hosting capacity, defined as the maximum RES capacity that can be installed without having any technical and operational problems, of the network exceeds its limit due to the increased integration of RESs to the existing network. This paper reviews the progress made in HC assessment and enhancement of electrical networks research and development since its inception. Attempts are also made to highlight the current and future issues involved in HC technology for the development of an affordable, in-exhaustive, clean and reliable power supply for longer term benefits
