Modeling, Integration, and Simulation of the 20 MW Photovoltaic Power Plant in the Saudi Arabia Distribution Network Considering LVRT Capability

Abstract

The evolution of Saudi Arabia’s electricity sector has accompanied distinct phases, culminating in a modern era marked by a solid commitment to renewable energy development, notably through the establishment of renewable energy power plants since 2010. Given the country’s diverse topography, there’s a keen interest in exploring renewable energy technologies, with a particular focus on solar energy. Saudi Arabia’s strides in renewable energy could serve as a blueprint for other nations aiming to embrace clean energy transitions. This article explores the impact of high photovoltaic (PV) energy penetration on the transient stability and voltage regulation of Saudi Arabia’s distribution power system. The study analyzes time response simulations to grid disturbances through modeling and simulation using PSSE and PSCAD-EMTDC software. Managing reactive power from solar power plants is crucial for seamless PV integration into power grids across varied operational scenarios. Various network faults, such as the disconnection of heavily loaded buses and three-phase short circuits at PV solar farms, are examined. The findings aim to pinpoint necessary protective measures and operational strategies for ensuring system stability and reliability, especially during transient events and grid fault recovery operations. Consequently, this study holds practical significance for utility planning and operation.
