Voltage and Reactive Power Control in Distribution Networks Based on the Optimal Allocation of Photovoltaic Systems: Case Study Mazar-e-Sharif Distribution Network

Abstract

ABSTRACT

In recent years, the increasing demand for reliable and sustainable energy in Afghanistan, particularly in urban areas such as Mazar-i-Sharif, has highlighted the need to improve the performance of power distribution networks. This study aims to propose solutions for voltage control and reactive power management in distribution systems, focusing on the optimal placement of photovoltaic PV systems. The main research problem is to investigate the impact of renewable energy integration—especially solar PV systems—on power quality, voltage profiles, and the stability of the Mazar-i-Sharif distribution network. By analyzing the current status of Afghanistan's power grid and applying intelligent optimization algorithms, this research explores technical solutions to reduce energy losses, control voltage fluctuations, and enhance power quality. The innovation of this study lies in the integration of optimal PV placement with smart reactive power management while considering power quality constraints in a real-world distribution network. Expected outcomes include improved voltage profiles, reduced network losses, and enhanced system stability. This research can contribute to the development of renewable energy infrastructure and improved quality of life in underserved regions of the Afghanistan.
