Abstract
This paper deals with the implementation of the control strategy for a three-phase voltage source inverter (VSI) system with the purpose of improving the power quality and controllability of photovoltaic (PV) system for microgrids (MGs) integration by means of energy storage system. The proposed model comprises of a PV power plant with an energy storage system coupled to the grid by means of a VSI. The PV system and the battery storage are integrated with the help of DC-DC and DC-AC converters in such a way that bidirectional flow of active and reactive powers can be achieved. The required power for the connected loads can be effectively delivered and supplied by the proposed PV system and energy storage systems, subject to an appropriate control method. The ultimate goal of any power system is to maintain a balance between demand and supply of active power at any set point in time. Controllers integrating energy sources respond to the received signals and attempt to fulfil the grid demand. The system response is almost instantaneous and thus can be very helpful in grid frequency and voltage support. The grid voltage harmonic generation influences the PI current controller and generates current harmonics; the used harmonic compensator is effective for both positive and negative sequence fifth and seventh harmonics. The proposed control system is validated by means of simulation results.
