Abstract: This paper illustrates a new compilation of Micro-grid by distributed energy sources using three phase three -level Space vector multilevel inverter. In olden days only 3Φ inverter was designed and they were connected to the consumer with higher harmonics without automatic control feeding power to the consumer end. But this system we implemented three phase three level inverter was fed power to the consumer and also reduces the switching losses. I have connected three renewable sources are alike Wind-turbine, P.V - cell and Pico-Hydel generator model to increases the potential of power supply to a relatively small jumble of people, an official of the economic lay of a locality. Furthermore costless new semiconductor technologies in the power switches beside the necessity of current on giant consummation inverters necessitate by Renewable-Energy-Systems (R.E.S) by reduced Total-Harmonic-distortion (T.H.D) in the spectrum of switching waveform have expanded the applications of Multi-level inverters. This system also includes M.P.P.T electronic control to operate maximum point of modules so, it is supplying maximal power to the consumer connected load according to the changes in solar-radiation and diffusive-temperature and intern increase the battery charging current.
