One of the major problem faced by the Indian power grid system are the excess use of energy. The utilization of renewable energy is the only solution to overcome this deficiency. Here we propose a system with photovoltaic system as renewable energy source act as a microgrid serving the grid. But while integrating, the power system stability is a crucial criteria. Inorder to facilitate powerful and flexible control infrastructure in future smart power grids, it is very essential to obtain the seamless formation and robust control of distributed generation microgrids. To achieve this objective, this paper presents a control structure for microgrid converters based on two controllers direct voltage controller and transient droop controller for power sharing. The proposed scheme have a salient feature of minimum switching actions between grid connected and isolated microgrids systems so that it minimize the internal microgrid formation disturbances like voltage magnitude disturbances and power angle swings associated with mode transition and load disturbances. This idea was implemented in MATLAB Simulink with photovoltaic as the source with controlling part to mitigate all the disturbances, to obtain the stable system.
