Over the years, power converters have found wide application in grid interfaced systems, including distributed power generation with renewable energy sources. In distributed energy systems like solar, hydro or any diesel generation where the output of the system is DC and is expected to be converted in AC, an inverter is used. There are various modes to have a controlled output of inverter. This output is to be controlled such that there should be balanced supply when inverters are connected in parallel. It is consists of three phase Voltage Source Inverter control scheme which is called as Proportional controller. In PI control, the stationary reference frame is used to transfer the feedback quantities from load side to source side. In this process, the decoupling of d and q components arises which is little complex. The PI controller is adopted in the most familiar dqo reference frame. The three phase system is simulated in the matlab-simulink environment with the controller and experimental results are given to prove the correctness and feasibility of the system. The droop control technique is all about sharing of the Active and Reactive powers between parallel connected inverters connected in Mini-Grid system. The sharing of power will be based on the ratings of the inverter when they are subjected to any change in load. The renewable Energy sources can meet the new load requirement in manner determined by its frequency and Voltage Droop Characteristics, The focus on a control Strategy that will be for the operation of Parallel inverter based micro-grid. This technique is important because, there is no external link is required between the inverters to share the load.
