Surplus energy refers to the excess electricity that is not consumed when the power generation exceeds the current load demand, which is common in renewable energy systems such as wind and solar energy. In the battery industry, the utilization of surplus energy is directly related to: the design capacity of energy storage systems: energy storage systems need to have sufficient capacity to absorb surplus energy to avoid the phenomenon of ‘waste of wind and light’. Peak shaving and valley filling strategy: store the surplus energy during the off-peak period and release it during the peak electricity consumption period to achieve grid balance. Economic benefit improvement: by capturing surplus energy through energy storage systems and selling electricity or using it for other loads, maximum revenue can be achieved.
