ESS PCS-1725 Power Conversion System Grid-Type Energy Storage Converter (Indoor)

A Power Conversion System (PCS) is the central power electronics component designed for efficient energy form conversion and control.

The ESS PCS-1725 is a high-performance grid-forming (GFM) power conversion system (PCS) designed for large-scale energy storage applications, including grid-side frequency regulation, renewable energy integration, and microgrid support. It features 1,725kW power capacity, SiC-based topology, and modular architecture, making it suitable for utility-scale projects requiring high efficiency and reliability

Key Technical Specifications

Core Features:
✅ Grid-Forming (GFM) Capability:

• Provides synthetic inertia and black-start functionality for off-grid/microgrid operation.

• Supports VSG (Virtual Synchronous Generator) mode for stable grid synchronization.

✅ Ultra-Fast Response:

• <10ms reaction time for frequency regulation (FFR/FCR) and voltage support.

✅ Modular & Scalable:

• Supports N+X redundancy and hot-swappable power modules for minimal downtime.

✅ Advanced Thermal Management:

• Liquid cooling ensures stable operation in extreme temperatures (-30°C to +60°C).

Application Scenarios

(1) Grid-Side Energy Storage

• Frequency Regulation (AGC):

  • Provides ±2% deadband control for grid stability (e.g., PJM market compliance).

• Peak Shaving & Renewable Smoothing:

  • Mitigates ±15%/min PV/wind fluctuations (IEC 61400-21 compliant).

(2) Renewable Integration

• Solar/Wind Hybrid Plants:

  • Enables DC-coupled systems for higher efficiency (vs. traditional AC-coupled setups).

• Inertia Emulation:

  • Mimics synchronous generator behavior to support weak grids.

(3) Microgrid & Off-Grid Systems

• Black Start Capability:

  • Can restart 0.2C discharge rate without external power.

• Multi-PCS Parallel Operation:

  • Enables MW-scale deployments (e.g., islanded industrial parks).

Competitive Advantages vs. Industry Peers

Why It Stands Out:

• Higher power density (smaller footprint per MW).

• Lower switching losses (SiC vs. IGBT).

• Better grid support (GFM for unstable grids)10.

Future Development Trends

• AI-Powered Predictive Control:

  • Integration with digital twin for real-time efficiency optimization.

• Hydrogen Hybridization:

  • Potential coupling with electrolyzers for long-duration storage.
