ACCU-100 Microgrid Coordination Controller

ACCU-100 Microgrid Coordination Controller

1. Product Overview
The ACCU-100 Microgrid Coordination Controller is an intelligent coordination controller designed for applications in microgrids, distributed generation, energy storage, and related fields. The device supports the integration of photovoltaic systems, wind power generation, energy storage systems, charging piles, and other equipment. By performing real-time data collection and analysis, it monitors the operational status and health of photovoltaic arrays, wind turbines, energy storage systems, and charging piles. Based on this data, the controller generates optimized control strategies aimed at achieving safe and economical operation. It dynamically regulates distributed energy resources, energy storage systems, and loads within the microgrid to enhance local consumption of renewable energy, improve grid stability, and compensate for load fluctuations. Additionally, it enables effective demand management, increases microgrid operational efficiency, reduces power supply costs, and ensures secure, reliable, and economical microgrid operation.

2. Product Features
The ACCU-100 Microgrid Coordination Controller offers the following functional advantages:

• Data Acquisition: Supports multi-channel real-time operation via serial ports, Ethernet, and other interfaces to connect with wind turbines, photovoltaic inverters, energy storage systems, and more.
• Communication Management: Compatible with communication protocols such as Modbus RTU, Modbus TCP, IEC 60870-5-101, IEC 60870-5-103, IEC 60870-5-104, and MQTT. Enables cloud-edge collaboration (remote operation and maintenance via Acrel Smart Energy Management Cloud Platform), OTA upgrades, local/remote mode switching, and local HMI interaction (optional).
• Edge Computing: Features flexible alarm threshold settings, proactive alarm notifications, data aggregation and calculation, logic control, breakpoint resume, data encryption, and 4G routing.
• Strategy Management: Includes anti-reverse power flow, scheduled curves, peak shaving and valley filling, demand control, active/reactive power control, photovoltaic-storage coordination, and supports customized control strategies.
