Typical utilization rates range from 15-35% globally, but smart management can push this to 50%+ in some applications. Different sectors require tailored approaches: 1. Renewable Energy Integration 2. Performance metrics such as efficiency and dispatchability greatly influence utilization, 2. The integration with renewable energy sources enhances storage effectiveness, 3. A system that can discharge four hours of energy can also discharge eight hours—just at half the power. LTES simply means a low power-to-energy ratio. Therefore, this paper starts from summarizing the role and configuration method of energy storage in new energy power stations and then proposes multidimensional evaluation indicators, including the solar curtailment rate, forecasting accuracy, and economics, which are taken as the optimization. The four core indicators — equipment availability, operational efficiency, depth of discharge (DOD), and battery capacity degradation rate — measure the “availability, economy, safety, and longevity” of energy storage plants. Availability determines “how long it can run” (full-power continuous. This data was used to determine electrical power and energy consumption, regenerative braking power and energy, on board resistor power and energy dissipation, and total electrical energy available from braking (regenerative or non-regenerative).
