Home Energy Storage System (HESS) plays a crucial role in modern energy utilization. With the increasing popularity of renewable energy sources such as solar and wind power, these energy sources have the characteristics of intermittency and instability. Home energy storage systems can store the excess electricity generated by renewable energy during the production – peak periods, and release it when the power generation is insufficient or during peak electricity consumption periods. This not only improves the self – consumption rate of renewable energy in households but also helps to reduce the dependence on the traditional power grid, lower electricity bills, and enhance energy independence. Moreover, it can provide emergency power in case of power outages, ensuring the normal operation of essential household appliances. Home Energy Storage System
