St Johns Outdoor Communications Power BESS Information

This thesis project, carried out at Northvolt Systems, aims to analyze the existing and readily used communication interfaces for a specific set of mobile BESS applications. The analysis is performed by a literature review of typical mobile BESS applications with the identified corresponding communication interfaces.

Due to the flexible and mobile nature of mobile BESS, the environmental conditions can difer greatly for each system depending on the respective mobile deployments. Ranging from high temperatures and high humidity to the inverse during the same season, monitoring and control of the TMS is critical.

The project aims to perform a thorough analysis of the various communication interfaces applicable to the applications that a mobile BESS can help support, of which, some typical VMS applications are construction sites, festivals, and EV charging stations.

A summary of the operational functions deemed interesting for mobile BESS operations are presented and explained below. DAGC: This operating function, Automatic Generation Control, is utilized by the balancing authority to control the DER active power output for managing the asset, mainly for frequency regulation .

Accommodating novel and state-of-the-art BESS coordination and protection capabilities. Furthermore, such a coordination scheme could be utilized to efectively connect multiple VMS and other mobile BESS in an efective manner, for an interoperable coordinated mobile system DER.

As presented in, coordinated voltage control strategies for mobile BESS units shows mitigation of voltage violations by coordinated regulatory actions with transformer tap changers, capacitor banks and photo-voltaic generation in a distribution network.
