​Abstract
In this paper presents automatic voltage and frequency regulations in a grid connected solar PV systems using SEPIC Converter with Fuzzy Logic Controller (FLC). This method allows effective control over active and reactive power available from the grid to PV system and vice-versa. A SEPIC converter is used to improve the performance of the system and also increasing the efficiency in better manner. The PV plant and the battery storage are integrated with the grid with the help of dc-dc and dc-ac converters in such a way that bi-directional flow of active and reactive powers can be achieved. When up regulation is occurred energy is transferring from PV to grid for regulate the voltage. Similarly, when down regulation is occurred energy transferring from grid to PV to regulate the frequency. Controllers integrating energy sources respond to the received signals and attempt to fulfill the grid demand. The system response is almost instantaneous and thus can be very helpful in frequency and voltage regulation.
