General
Acrel ACCU-100M Microgrid Coordination Controller is a modular intelligent coordination controller applied to microgrid, distributed power generation, energy storage and other fields. ACCU-100M microgrid coordination controller is a modular intelligent coordination controller applied in the field of microgrid, distributed power generation and energy storage.
The device meets the system requirements for the access of photovoltaic system, wind power generation, energy storage system and charging piles, etc. It monitors the operation status and health condition of photovoltaic, wind power generation, energy storage system and charging piles through round-the-clock data collection and analysis of the microgrid system, and on the basis of which, with the target of safe and economic optimisation of operation, it obtains the optimal control strategy and then implements the regulation and control on the microgrid, realising real-time dynamic regulation function of the distributed energy.
It can achieve real-time dynamic regulation of microgrid distributed energy, energy storage system and load, promote localised consumption of new energy, improve the stability of grid operation and compensate for load fluctuations; effectively implement demand management of microgrid, improve the operating efficiency of microgrid, reduce the cost of power supply, and guarantee the safe, reliable and economic operation of microgrid.
