Battery Energy Storage Systems (BESS) are starting to play an important role in today´s power distribution networks. They provide a manifold of services for fulfilling demands and requests from diverse stakeholders, such as distribution system operators, energy market operators, aggregators but also end-users. Such services are usually provided by corresponding Energy Management Systems (EMS). This paper analyzes the complexity of the EMS development process resulting from an evolving power utility automation. As a result, flexibility, complexity, interoperability, and overlapping issues were identified as main concerns to be faced during the design and implementation stages of BESS control applications. Current efforts from smart grid and power utility automation standards partially tackle the issues mentioned above. Nevertheless, an integrated methodology that guides and supports control engineers during the whole development chain is still missing. Hence, the conception of EMSOnto is introduced. The main achievements of this approach include the alignment of BESS design with broadly accepted smart grid standards (i.e., IEC 61850, smart grid architecture model), a common understanding of EMS control applications based on the conception of an ontology, the identification of conflicts within a multi-function BESS and the semi-automatic generation of software artifacts mainly important for EMS validation. To demonstrate the effectiveness of the approach, a selected use case example is designed and validated in a hardware-in-the-loop basis. This proves that EMSOnto eases the work of control engineers resulting in a flexible, adaptable, and error-free EMS design. In addition to this, limitations of EMSOnto as well as future work are grasped.
