Abstract: This concept presents a fully DC-operated microgrid designed to ensure the uninterrupted energy supply of critical loads by integrating photovoltaic (PV) energy generation, real-time solar insolation prediction, fault detection, and comprehensive energy demand monitoring. When the system is powered ON, the PV solar panels begin to absorb sunlight and convert it into DC electricity. The amount of solar energy produced depends on the current solar insolation, which is detected by the LDR. The boost converter ensures that the voltage from the solar panels is regulated and compatible with the battery charging requirements. The EMS initializes, beginning to manage and monitor the flow of energy. It communicates with all system components, including the batteries, converter, sensors, and grid interface. When excess energy is generated, more than what is being used by the critical load, it is directed towards charging the batteries. The current and voltage sensors continuously monitor electrical parameters such as voltage and current. They provide feedback to the EMS to ensure that the voltage levels remain within safe ranges and that the system operates efficiently. We can be able to see the real-time of the entire energy flow by using the LCD. By predicting solar insolation and detecting faults in the solar panels, the system proactively adjusts to meet energy demands, ensuring reliability and efficiency in powering critical loads.
