Acrel-2000MG Microgrid Energy Management System — Digitally Empowering the Safe Efficient and Economical Operation of Microgrids

Core System Positioning: Monitoring + Management — A One-Stop Microgrid Solution

The Acrel-2000MG Microgrid Energy Management System is compatible with the integration of diverse equipment—such as photovoltaic (PV) arrays and energy storage systems—enabling round-the-clock data acquisition and intelligent analysis. It provides real-time monitoring of the operational status and health condition of key subsystems, including PV generation, energy storage, and electrical loads. Built upon a foundation of safety and stability, and driven by the objective of economic optimization, the system facilitates the efficient absorption of renewable energy. It achieves "peak shaving and valley filling" (load leveling) and load smoothing, thereby comprehensively enhancing grid operational stability and equipment efficiency while simultaneously reducing power supply costs. Ultimately, it establishes a new operational paradigm—one that is safe, reliable, and economically efficient—for enterprise-level microgrids.

Dual Architecture Adaptability: Comprehensive Coverage for Grid-Connected and Off-Grid Scenarios

The system supports two core architectural modes—grid-connected and off-grid—offering flexible adaptability to meet the diverse energy requirements of various operational scenarios:

Grid-Connected Functionality

The system interfaces directly with the central dispatch center, enabling remote monitoring and control via Web interfaces, mobile applications, and the Acrel EMS platform. By integrating with power forecasting workstations and remote telemetry units (RTUs), it orchestrates the coordinated operation of various components—including the main power grid connection, power quality monitors, microcomputer protection relays, and intelligent gateways—to ensure the seamless, synchronized performance of PV arrays, energy storage systems, EV charging piles, and electrical loads within the grid-connected environment.

Off-Grid Capability

Leveraging local Web/App interfaces, an EMS (Energy Management System), and a Power Forecasting Workstation, the system utilizes smart gateways to interconnect various assets—including PV arrays, energy storage units, and diesel generators. This ensures a stable power supply for independent microgrids, making it ideal for scenarios lacking grid coverage or those with exceptionally high requirements for power supply reliability.

Eight Core Functions: Comprehensive Microgrid Management

System Overview:

One-stop collection, real-time monitoring, and visual display of data from PV arrays, wind turbines, energy storage systems, loads, EV charging stations, and environmental sensors.

Device Monitoring:

Real-time status monitoring of key equipment—including PV modules, inverters, PCS (Power Conversion Systems), BMS (Battery Management Systems), and charging stations—with support for anomaly alerts, revenue statistics, event logging, and report generation.

Power Forecasting:

Achieves highly accurate short-term and ultra-short-term PV power forecasting, while intelligently predicting load power curves based on historical data.

Control Strategies:

Supports a triple-mode control framework—Manual, Automatic, and Optimized—to facilitate scheduled power curves, peak shaving and valley filling, anti-reverse flow protection, renewable energy absorption, and demand control.

Energy Analysis:

Conducts multi-dimensional analysis of energy consumption, economic benefits, and operational efficiency to provide essential data support for intelligent O&M (Operations & Maintenance).

Economic Dispatch:

Constructs dispatch models based on Time-of-Use (ToU) electricity tariffs, grid interaction power levels, and energy storage status, intelligently optimizing system operation with the primary objective of minimizing electricity costs.
