With the extension of 5G networks to remote mountainous areas, grasslands, islands and other regions, the construction of base stations has ushered in large-scale development, but it has also brought power supply challenges. According to statistics, the total number of base stations in China has exceeded 3.7 million, of which about 15% are facing practical problems such as unstable power supply, difficult operation and maintenance, high energy costs, and high energy consumption. How to ensure the continuous and stable operation of base stations in off grid or weak grid areas far away from stable power grids has become a key breakthrough in the industry.

In this context, optical storage integrated machines, as the core path for upgrading base station energy systems, are gradually entering the industry's vision. To truly achieve efficient collaboration and intelligent scheduling of "photovoltaic+energy storage" in the photovoltaic storage system, a reliable and intelligent "brain" is indispensable——Ankerui ACCU Coordinated ControllerIt was born for this purpose.

Smart brain, panoramic perception

ACCU microgrid coordination controller is an intelligent coordination controller applied in microgrids, distributed generation, energy storage and other fields. The device meets the system's requirements for connecting photovoltaic systems, wind power generation, energy storage systems, and charging piles. Through all-weather data collection and analysis of the microgrid system, the operation status and health of photovoltaic, wind power, energy storage systems, and charging piles are monitored. Based on this, with the goal of safe and economic optimization operation, control strategies are obtained to implement regulation and control of the microgrid, realizing real-time dynamic adjustment functions of distributed energy, energy storage systems, and loads in the microgrid, promoting the local consumption of new energy, improving the stability of grid operation, and compensating for load fluctuations; Effectively implement demand management for microgrids, improve operational efficiency, reduce power supply costs, and ensure safe, reliable, and economical operation of microgrids.

As the "smart brain" of the optical storage integrated machine, the Ankerui ACCU coordination controller has built a full chain management system from precise perception and intelligent decision-making of the optical storage integrated cabinet to remote operation and maintenance.

Flexible strategy, precise control

Faced with the differences in power grid policies, climate conditions, and load characteristics in different regions, ACCU provides highly flexible control strategies to adapt to diverse scenario requirements:

Plan curve control: supports custom energy storage charging and discharging time and power, especially suitable for regions implementing time of use electricity pricing. Through peak valley arbitrage, it effectively reduces electricity expenses and improves operational revenue.

Anti backflow control: Real time monitoring of the power flow direction at the grid connection point. Once the trend of power backflow to the grid is detected, the output of the energy storage converter (PCS) is dynamically adjusted to ensure strict compliance with grid requirements and avoid fines for violations.

Overload prevention control: Intelligent monitoring of the upper level transformer load. When the total load approaches the set threshold, it automatically reduces the energy storage charging power or switches to discharge, effectively preventing transformer overload operation and ensuring power supply safety.

Backup power control: The energy storage reserve capacity can be pre-set, and the system will intelligently maintain this part of the power reserve. It will only be automatically activated when the mains power is abnormal, providing uninterrupted and reliable power supply for the core load.

Remote operation and maintenance, efficient management

With the help of communication methods such as 4G and Ethernet, ACCU uploads real-time on-site data to the Ankerui Smart Energy Management Cloud Platform, achieving a leap from "manual inspection" to "remote intelligent operation and maintenance".

Operations personnel can access the operational status, power generation data, energy storage capacity, alarm information, and other information of base stations distributed across the country anytime and anywhere through mobile apps or computer web pages, greatly improving operations efficiency and reducing labor and travel costs.

Boundless applications, the future has arrived

Thanks to its highly integrated, intelligent, and reliable design, the Ankerui ACCU coordination controller is rapidly expanding its application scenarios beyond communication base stations. It can also serve as an energy management center in off grid, weak grid, and non grid scenarios such as border posts, field camps, fishing and animal husbandry agricultural parks, oil fields and mining areas, and temporary construction projects, integrating multiple types of energy such as photovoltaics, energy storage, and diesel generators to build a stable, efficient, and green off grid microgrid system.
