Abstract—The thirst for energy has brought out the existence of grid connected solar photovoltaic systems to meet out the reduction in the energy bill, which act as a cost saving methodology with simultaneous gain of incentives from the government for transporting the power to the national grid. Hence the operational objectives and the control strategies employed for its efficient operation are to be well studied. This paper thus discusses in detail about its topology, grid standards, real time challenges and objectives incorporating even the ancillary control schemes. A review is made on the control techniques which are made available for the DC (PV side) and AC side (grid side). A comparative analysis is made on each of the techniques based on the response parameters concluding the suggestion of most appropriate strategy for tolerable operation of grid connected photovoltaic systems.
