Study of Micro Grid System

Abstract

The electric power system has evolved through large, central power plants interconnected via grids of transmission lines and distribution networks that feed power to customers. The system is beginning to change – rapidly in some areas – with the rise of distributed energy resources (DER) such as oil-fueled generators, combined heat and power plants, electricity storage, and solar photovoltaic (PV) on rooftops and in larger arrays connected to the distribution system. In many settings DER already have an impact on the operation of the electric power grid. Through a combination of technological improvements, policy incentives, and consumer choices in technology and service, the role of DER is likely to become more important in the future. Many governments as a way of handling energy independence promote such a modern electricity network. The idea of the project is to evaluate the effect of adding PV generation on the distribution system and its influence on transmission line, how it can decrease the losses and increase the efficiency of the power generation by using new technology called distributed generation. For the simulations, we used a specialized simulation tool; ETAP, which is one of the best available tools for simulating power systems and renewable energy resources.
