ESS PCS-2500 Power Conversion System With Strong Adaptability Of Power Grid

ESS PCS-2500 Power Conversion System With Strong Adaptability Of Power Grid

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

The ESS PCS-2500 is a high-performance grid-forming (GFM) power conversion system (PCS) designed for large-scale energy storage applications, including utility-scale battery storage, renewable integration, and microgrid support. With a 2,500kW (2.5MW) power rating, it features SiC-based topology, modular architecture, and advanced grid-support functions, making it ideal for projects requiring high efficiency, scalability, 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) Utility-Scale 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).

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.

For customized technical proposals, provide:

1. Site single-line diagram (SLD)

2. Grid compliance requirements (e.g., IEEE 1547-2018, EU RfG)

3. Battery type (e.g., LiFePO4, flow batteries)
