Distributed Generation: Impacts and Cost Analysis

Abstract

This paper presents the reason for the current interest in distributed generation and the challenges that are faced while increasing its share in the electricity generation mix. Under the present centralized generation paradigm, electricity is mainly produced in bulk amount at large generating stations, wheeled though the transmission and distribution grids to the end consumers. However, the recent quest for energy efficiency and reliability and reduction of greenhouse gas emissions led to explore possibilities to alter the existing generation paradigm and increase its overall performance with the implementation of distributed generation.

Optimal Allocation of Renewable Distributed Generators and Electric Vehicles in a Distribution System Using the Political Optimization Algorithm

“…As a result, an alternative energy source, such as a fuel cell or energy storage, is necessary. PV systems, wind turbines, and SOFCs are considered DGs in this study, and FC is also employed as a backup source [3,5]. Plug-in electric vehicles (PEVs) are considered dynamic loads during the charging phase and demand electricity from the current grid infrastructure.…”
