Design and Integration of Distributed Generation Systems to Dongola Distribution Grid

Abstract

There is a large and rapid increase in the demand for electricity which causes a lack of electricity supply from centralized generation. Centralized generation is characterized by several challenges including that a high power loss in both transmission and distribution lines, high maintain and operation costs and high emissions which increase the different pollution due to exhaust from fossil-fired gas or coal boilers plants. These limitations in terms of efficiency and environmental impacts have given rise to Distributed Generation (DG) options for researchers and policy makers. Distributed Generation refers to any electric power production technology that is integrated within distribution systems, close to the point of use. DGs are connected to the medium or low voltage grid. There are several technologies of DG in the market. Some are conventional such as the diesel generators and some are new technologies such as renewable energies. Renewable energy is that clean, unpolluted, environmental friendly type of energy which is obtained from natural resources that exist every day and always well as earth exists, such as sun light and wind. This project develops a study of the design of PV and wind DG systems to be implemented in Dongola Distribution grid at 11 kV. The study aims to find the parameters of the PV and the wind DG systems such that it can function correctly. In addition, it investigates the impact of integrating these DG systems directly with the existing grid. In order to prove the design validity of the proposed system, models and simulations in PVSYST and ETAP programs will be established for a practical distribution grid. Real loads, solar and wind energies data will be used in the simulation models for more realistic design. The results obtained from the analysis will be presented, tabulated, and discussed throughout this work.
