2025-06-19 16:13:01

As the penetration rate of renewable energy continues to rise, the challenges to power system stability are becoming more severe. Energy storage systems have emerged as essential buffers coupling new energy with the grid. At the core of these systems lies the Energy Storage EMS (Energy Management System), not only responsible for daily dispatching tasks but also key to unlocking market participation, profit maximization, and system security in the future.

4.Key EMS Strategy Types and Application Scenarios
