Effect of Multi-wind Distributed Generators Location during Fault Occurrence in Distribution System

Abstract

In the recent decade, there has been a rising concern about energy consumption and environmental issues. This trend has shifted the focus of electric utility from fossil fuels to renewable energy. Thus, distributed generation (DG) that generated power from renewable energy sources has been on the rise. However, the presence of DG can affect the operation of power system protection and may cause a technical issue with the equipment. So, this paper investigates the impacts of wind power-based DG installed on the distribution system in Thailand using PSCAD software. The case study system is modeled after part of the Provincial Electricity Authority (PEA) distribution network in Northern Thailand. The comparative study with the case without DG has also been done on various parameters such as type of faults, location, and number of DG. The result from a study reveals the impact of DG on the distribution system characteristics, which changing drastically. Thus, an analysis of the impact of DG on the system must be done to address its effects and ensure the reliability of the power system.
