The proposed Microgrid Black Start and Restoration System is designed to provide continuous power supply to loads when the main grid source is unavailable. In such conditions, the system independently generates and supplies the required voltage and current using renewable energy sources through controlled H-bridge inverter operation. solar and wind energy are used as primary sources. The solar power flows through a charging circuit to charge the battery, and the stored energy is then converted from DC to AC using an H-bridge inverter. The inverter output is stepped up using a transformer and supplied to the critical load through relay-based switching. Similarly, wind energy is processed through its charging circuit and battery, converted using another H-bridge inverter, stepped up through a transformer, and supplied to the non-critical load through relays. Four potentiometers are used to vary and control the voltage and frequency of both solar and wind sources, enabling flexible power regulation. The PIC microcontroller performs grid-forming inverter control by generating appropriate PWM signals to the H-bridge circuits, thereby providing the required frequency and voltage for load supply. In case of a fault occurring in the grid-forming inverter, the system performs automatic fault rectification to ensure uninterrupted operation. The ESP32 microcontroller is used for monitoring and IoT communication. It uploads key system parameters such as solar voltage, wind voltage, frequency levels, and relay ON/OFF status to a web interface. An LCD display provides local monitoring, while LED indicators show system status. Thus, the system enables black start capability and autonomous microgrid restoration, ensuring reliable power supply to both critical and non-critical loads even in the absence of the main grid.
