A smart micro-grid design is necessary for the combination of distributed energy sources into the electrical energy
distribution chain. There are different classes of micro-grid constructions that have been produced and performed in the last
decades. These micro-grid constructions have their essential benefits and constraints. This work has been developed to recognize
and discuss, essential trials and solutions for combination of micro-grid into the distribution chain.
In this work two micro grids, one with combination of PV, Wind, Battery system, another with the combination of PV, DG,
Battery system are developed the THD and cost analysis is been carried out to select best combination among the two.
