Modeling of Solar Energy Grid Integration System Using Typhoon HIL

Abstract

This paper presents modeling of grid integrated solar photovoltaic system using Typhoon Hil. Renewable energy sources mainly wind and solar are widely used for power generation. Solar energy can be used for both stands alone and grid tied application. The photovoltaic system consists of Photovoltaic panel through DC to DC converter along with MPPT algorithm and DC to AC inverter to feed solar energy in grid line. Here P&O MPPT algorithm used for extracting that point where power is maximum at different environmental condition. Presently there are many types of MPPT control algorithms are available but in this work Perturb & Observer MPPT control method is used. In additional PWM technique is used for control the inverter. Three phase voltage source are connected at grid side for operate the load.
