ENHANCEMENT OF POWER QUALITY IN SAPS SYSTEM WITH MULTILEVEL INVERTER

This paper presents a standalone hybrid power system by the use of wind/PV/diesel energy system in Matlab/Simulink environment. PV & Wind are the basic power sources of the system. The most frequently used renewable energy sources are those consisting of PV module and/or wind Turbine with/or Diesel generator. Multilevel inverters play a vital role in today's interconnected grid systems with renewable energy sources. Those power electronics devices which converts DC input power to AC at required output level of voltage and frequency are known as inverters. They are used for high voltage and high power applications, with the improved advantages of low switching stress and reduced total harmonic distortion (THD), hence they reduce size of the passive filters. Multilevel inverter can be used with this standalone hybrid system for the electrification of rural areas to provide uninterrupted power supply.
