The article presents a method for managing a solar power system called a microgrid. The researchers used an energy circuit model to represent the system's structure, making it easy to simulate on a computer. They also developed a way to adjust energy use based on probabilities, which helps estimate uncertain power needs. By applying this method to the system's energy management strategy, they found that it can reduce the time and cost of running the system. Overall, the study shows that this approach is effective for improving the efficiency of microgrid energy systems.
