As the demand for renewable energy integration into power grids increases, so does the need for sophisticated Battery Energy Storage Systems (BESSs). The core of managing these systems effectively lies in the use of Data Acquisition Systems (DAS), which monitor and collect data crucial for optimal operation. Typically integrated with Supervisory Control and Data Acquisition (SCADA) systems, DAS face stringent cybersecurity measures which may complicate operations and restrict data fluidity. This thesis proposes investigating the potential benefits and challenges of separating DAS from the SCADA pipelines in BESSs, aiming to enhance data efficiency and reduce cybersecurity complexities.

Scope of research:

  • Define General Requirements: Outline the fundamental requirements and available standards for BESSs concerning DAS, including data points and granularities, streaming needs, and integration with existing technologies.
  • Review Current Technologies: Examine main existing DAS technologies focusing on hardware and software needs, scalability, and integration with large-scale BESSs.
  • Assess DAS Implementations: Analyse the pros and cons of current DAS setups in BESSs, considering factors like required hardware & software resources, data granularity, reliability, and cost.
  • Investigate DAS Separation Potential: Explore the technical feasibility and additional requirements (hardware, software, safety) of separating DAS from SCADA systems.
  • Evaluate Security changes and Efficiency Gains: Describe the security impact by introducing a DAS system on top of SCADA. For example, discuss the potential reduction in cybersecurity requirements and the consequent impacts on system security and data availability.
  • Recommend Optimal DAS Solutions: Based on all previous analysis, conclude with recommendations for BESS
