Entering a Fresh Period of Authority: Interpreting the Primary Data Obstacles in Large Battery Energy Storage Systems

With the decline of coal power, we witness the emergence of extensive Battery Energy Storage Systems (BESSs) alongside an upsurge in renewable energy capacity. Breaking a technological gap that spanned over a century, industry innovators are amalgamating groundbreaking battery storage technology with established grid frameworks. Fine-tuning grid equilibrium and ensuring seamless operation of storage units presents a significant challenge. So, what’s their key to ensuring a prosperous energy transition? The solution is straightforward: data.

Throughout the sector, surveillance and management platforms—such as battery supervision systems (BMS) and energy administration systems (EMS)—are becoming as vital to energy storage as the batteries themselves. Deciphering the intricate jargon of system data is the inaugural step in ensuring the efficacy of these systems. Specialist expertise is essential for gathering and deciphering the data that empowers Operational Technology (OT).

Despite data being a potent instrument, it must be harnessed efficiently for dependable operation and advancement. Here are four distinct data hurdles that BESS must contend with:

1. The “Insufficient Data” Predicament​

​BESS transcends mere battery storage. Fire suppression systems, air conditioning, and power conservation systems may also pertain to this domain. Nevertheless, these diverse equipment types frequently utilize differing data transmission protocols and interfaces. Consequently, obtaining comprehensive status updates from these crucial devices can be challenging.

2. The “Unusable Data” Enigma

A 20/40-foot battery cabinet produces copious amounts of data per minute, encompassing temperature readings, voltage levels, and current measurements, among others. Evading bandwidth and processing inefficiencies while segregating valuable data from noise can be an arduous task.

3. The “Incomplete Data” Riddle

BESS plays a pivotal role in grid stability management, necessitating real-time regulation and site intelligence. For instance, efficient utilization of stored wind and solar energy demands in-depth monitoring and analysis of BESS system data, while grid stability mandates instantaneous automatic frequency control. Both applications call for comprehensive, high-speed data transmission, which can be facilitated through long-range communication and swift backup networks.

4. The “Insecure Data” Predicament

BESS integrates power generation, transmission, and distribution. This interconnectedness can expand the attack surface for cyber intrusions. To mitigate vulnerabilities and safeguard the power grid, robust security protocols are imperative for system providers.

Conquering these four data obstacles is pivotal for the consistent operation and progression of BESS. These systems must adjust to the evolving energy market to amplify the efficiency, dependability, and security of energy provision.
