Optimized PV-Generator Hybrid System with the Local Grid

Abstract

The development of any country or society depends on how sufficient electrical energy it has. Most of the energy needs of the world are being fulfilled by non-renewable sources of energy which it is in short supply and suffer from unreliability. Currently, the country is facing serious energy crisis with daily load shedding. This current scenario of load shedding affects the daily activities. Hence it is necessary to manage alternative way to fulfill electricity need. This research focuses on improving the current system by implementing a hybrid system consisting of a combination of Photo Voltaic (PV) solar System, Fuel generator and the national grid for the power sources, and an energy management system for the control using the Arduino controller. The administration building in Sudan University of science and technology has been selected as a case study for this research. Before designing the system, it is necessary to create a load profile for the electrical devices and then size of the PV solar panels, the capacity of storage system, inverter type/size, and the suitable generator. Also the overall system will be simulated using Proteus simulator to show the different cases of the system. The results show that the proposed hybrid power system can effectively ensure the reliability and Continuity of supply for the priority loads, reduce the monthly bills and consume less power from the utility grid
