Either convertor or AC rotating machine will act as an to connect DG with main grid. Higher degree sound technically feasible option will be provided interfaced DG is utilized. Among the various switching devices, higher voltage, low-switc insulated gate bipolar transistor (IGBT) inver voltage, high- switching frequency metal oxide sem effect transistor (MOSFET) inverter have gained in the research forum. Hence this paper mai average approach of converter interfaced DG with as switching devices with 180/120 degree supplyin serious RLC load. Voltage, current, real power, re total harmonic distortions are some of the imp parameters taken for study. Simulations are c MATLAB/Simulink platform.

INTRODUCTION The ever increasing power requirement in t commercial sector, along with the need of reliab is approaching the power systems towards Generation (DG) [1]. A microgrid is a uniq which consists of multiple DGs and cluster working is unrelated with the main grid [2]. T of microgrid enhances the power quality, transmission line costs, reduces the green hous and efficiently utilizes the renewable energy Power electronic converters are required to conn the utility grid [4] [5]. Basically there are tw inverter based DG (PV, Fuel cell) and non inv (Synchronous Generator). Some of the DG inverter interface to generate power at the gr practical layout of microgrid structure consi represented in the Fig.1. as belows: rence on Circuit, Power and Computing Technologies [IC ET: A comparative study r topology in distributed vendiran 1a , Swathi Chozhavendhan 1b , Thaniga.D 1c , R ociate Proffesor, Department of Electrical &Electron ring College, India, psk_siva@hotmail.com gineering College,India , SKP Engineering College,I 21@gmail.com 1b swathi.sasi26@gmail.com s a significant one power electronic interfacing media of flexibility and d when converter power electronic ching frequency rter and a lower miconductor field massive attention inly observes the h IGBT/MOSFET ng resistive(R) and eactive power and ortant significant carried out with ree phase inverter; N the industrial and ble power supply the Distributed que form of grid of loads, whose The establishment , decreases the se gas emissions y resources [3]. nect the DER and wo types of DG, verter based DG sources rely on rid frequency.
