As the build-out of modern power systems accelerates worldwide, CSG has introduced its advanced Grid-Edge Energy Storage System—a distribution transformer–deployed solution engineered for the outermost reaches of the distribution network. Integrated with the Company's proprietary AI-Enabled Energy Management System (AI-EMS) , the platform has evolved from a point solution for isolated grid challenges into a full-function intelligent control hub at the grid edge. It provides bi-directional energy storage and dispatch, dynamic power regulation, and comprehensive power quality correction, positioning it as a critical enabling asset for the next-generation power system.

Power Quality Assurance

The system delivers ±10% reactive power compensation capability, maintaining voltage deviation within the ±7% nominal range as prescribed by applicable grid-quality standards. Independent three-phase power regulation keeps three-phase current imbalance within ≤5%—the threshold widely recognized for distribution network performance.

Peak Load Shaving

Proprietary AI algorithms generate three-day load forecasts with ≥95% accuracy. The system dynamically coordinates charge/discharge cycles with distribution transformer infeed loading, automatically initiating discharge intervention when transformer loading exceeds 85%.

Renewable Integration Optimization

The system prioritizes storage of surplus PV generation, boosting on-site self-consumption by ≥30%. It actively smooths renewable output fluctuations, containing grid-connected power variability within 10% per 10-minute interval.

Seamless Grid-to-Island Transition

With a static transfer switch (STS), the system completes grid-connected to island-mode transition in milliseconds. In island mode, it independently maintains voltage and frequency stability, supporting local renewable energy consumption.

Multi-Objective Coordinated Optimization

Users can define custom operating priorities; the system automatically selects the optimal dispatch strategy. It continuously monitors battery state of health (SOH) and optimizes charge/discharge protocols to extend battery service life by ≥20%. The system communicates with transformer-area fusion terminals to enable coordinated energy dispatch at the distribution level.

Market Value Capture

The system is market-ready, capable of participating in electricity spot markets and ancillary service markets. It responds to demand response dispatch signals in milliseconds and reaches full discharge power output within 10 seconds. Value-added services include emergency backup power and virtual power plant (VPP) aggregation.

Against the backdrop of accelerating power system modernization, grid-edge energy storage is advancing toward higher integration, greater intelligence, and multi-scenario convergence. AI-driven load forecasting and autonomous decision-making, VPP aggregation, and coordinated distribution-microgrid autonomy are expanding the value frontier. Beyond addressing grid-edge power quality issues, CSG's Grid-Edge Energy Storage System is poised to become a cornerstone for the distributed energy ecosystem and a catalyst for the broader energy transition
