A Review Article on Comparison Between Utility Grid Connected V2G System and Without Utility Grid Connected V2G System

Abstract

Main purpose of this paper is to suggest an electricity generation system based on renewable energy sources to fulfill the electrical demand of remote areas of a developing country like India. The suggested system is composed of photovoltaic array and fuel cell stack. The system is known as Solar PV- Fuel cell system. The optimization and the simulation of the proposed system were performed on MTLAB/SIMULINK software. In order to determine the optimal combination of the system, different combinations of PV arrays, Fuel cell, were selected on the basis of the Net Present Cost (NPC). In the recent times the utilization of renewable energy sources has gained many advantages in today’s generation and among them is the PV cell which is attracting research scholars on day to day basis. In this paper the mathematical modelling of Photovoltaic cell (PV) using MATLAB MATLAB/SIMULINK tool is done. Maximum power point tracking (MPPT) is used for increasing the efficiency of the used PV. Due to the change in solar irradiance from day to night various problem arises. This problem is solved by integrating PV arrays with the Solid Oxide Fuel Cell (SOFC) and battery thus forming a standalone hybrid PV-SOFC-Battery generation system. Certain disadvantage of the PV system is that the output voltage is low so we need to boost its voltage using boost converter so that five level inverter would convert it into alternating form. The whole of the hybrid standalone system is connected to grid. The modelling of PV, SOFC and the five level inverter are done using SIMULINK in MATLAB.
