Energy management for power supply side and grid side

The CEMS (Cluster Energy Management System) integrates "energy consumption analysis" and "intelligent control". It has 16 core energy scheduling functions and 4 auxiliary functions, covering user-side energy storage control, grid-side energy storage control, multi-energy coordinated operation control (solar energy + energy storage + charging, wind and solar energy + energy storage, thermal power + lithium battery, compressed air + lithium battery), etc. Research and develop communication and coordinated control technology for virtual power plants, aggregate distributed resources and controllable loads, combine elements such as energy management, production capacity analysis, and equipment management. Through optimized resource allocation and coordinated scheduling, it stabilizes the fluctuation of new energy, promotes the consumption of new energy, and provides capacity support and auxiliary services for the power grid.
