With addition of DGs or Micro grids to the distribution system complexity increases substantially. Installing high performing DGs have many advantages. However if not implemented properly DGs can be become more harmful than beneficial. If these DGs are not properly controlled they may lead to grid instability. Implementation of renewable energy like Photo voltaic or Wind turbine based DGs usually requires implementation of both DC-DC converter and DC-AC voltage source Inverter (VSI). In our work we have specifically focused on DGs based on solar energy. In our proposed work we are using a PV Cell based power source, DC DC boost converter to convert low voltage DC to high voltage DC and finally a multi-level inverter to convert DC to AC. By using multi-level inverter we are able to produce better quality power and filters required to filter AC output will need low cost components. In order to simulate the results for different cases we created a SIMULINK model in MATLAB to generate our results. To generate all desired results we created two Models in MATLAB. First Model is based on conventional boost converter and conventional three phase inverter. While the second one is based on interleaved boost converter and five level diode clamped multilevel inverter. Simulation results confirm that proposed method performs better than conventional method.
