Numerical Analysis of On-Grid Photovoltaic System and O-Grid Wind-Turbine Asynchronous Generator Using Simulink

Abstract

This work focuses on a program developed in stimulant of 100-kw and turbine asynchronous generator .This program simulates PV ar- ray using an equivalent circuit model including a photocurrent source, a diode, a series resistor and a shunt resistor .The PV module is the interface which converts light into electricity. Modeling this device always requires taking climate factors (irradiance and temperature) as input variables. The output can be current, voltage, energy or other variables.The common ve-parameter model was selected for the present study, and solved using a novel combination technique which integrated an algebraic simultaneous calculation of the param- eters at well known test prerequisites (STC) with an analytical dedi- cation of the parameters under real running conditions. A monocrys- talline photo voltaic module was simulated using MATLAB/Simulink software program at di erent ambient temperature and the output energy of cell was recorded. Solar Radiation and its e ect on energy of module is also simulated. Simulation shows that the output en- ergy of photo voltaic cell get decreased with reduce in sun's radiation and raising temperature also decreases the output.Additionally, this thesis also examines the operating characteristics of an o - grid wind turbine asynchronous generator . Wind energy capacity has grown rapidly as a share of worldwide electricity supply in recent years. In an isolated distribution network, a small-scale wind turbine generator is usually installed. This paper is intended to justify the fact that the intermittent power output of a small wind power capacity contributes to demand without interfering with the output power balance i
