“…The Common Information Model (CIM) has been recognized as a key element to connect different DSO systems and applications using a standardized data model and enable interoperability for smart grid applications (Hargreaves et al 2014;Ascher and Bytschkow 2018). In that, a substantial challenge consists in bridging the gap between applicationspecific data models and the application-independent CIM data model in order to make data accessible for applications requiring multiple data sources such as power system simulations.…”

Smart energy systems (SES) promote the transformation of the distribution grid towards more sustainable operation and planning strategies, but also impose a set of considerable technological and political challenges. In this, distribution system operators (DSOs) are faced with the necessity of adapting their information system landscapes to enable the efficient utilization of information within their internal structures. In this work, we propose a model-based approach to derive an open middleware platform supporting the integration of existing system landscapes of DSOs. For this, we shortly describe a domain analysis on the DSO domain, which we use to derive the requirements of our platform. The platform is then implemented utilizing the Common Information Model (CIM) and open standards. Finally, we demonstrate the applicability of our approach within a small case study for a single use-case.

“…The I3RES profile predefines the data-format, variable types, attributes and other details of the information model using relevant classes that are required for standardized communication among power system applications. The classes, attributes, and roles included in the standards IEC 61970-452 [24] and IEC 61970-456 [25] are chosen as the starting point for the profile implementation. The standard IEC 61970-452 provides the CIM base to facilitate applications for state estimation and power flow analysis.…”

Abstract-Two Major challenges in securing reliable Optimal Power Flow (OPF) operations are: (i) fluctuations induced due to renewable generators and energy demand, and (ii) interaction and interoperability among the different entities. Addressing these issues requires handling both physical (e.g., power flows) and cyber aspects (computing and communication) of the energy grids, i.e, a cyber-physical systems (CPS) approach is necessitated. First, this investigation proposes a receding horizon control (RHC) based approach for solving OPF to deal with the uncertainties. It uses forecasts on renewable generation and demand and an optimization model solving a predictive control problem to secure energy balance while meeting the network constraints. Second, to handle the interoperability issues, a middleware using common information model (CIM) for exchanging information among applications and the associated profiles are presented. CIM profiles modelling various components and aspects of the RHC based OPF is proposed. In addition, a middleware architecture and services to collect information is discussed. The proposed CPS approach is illustrated in a distribution grid in Steinkjer, Norway having 85 nodes, 700 customers, 3 hydrogenerators, and various industrial loads. Our results demonstrate the benefits of CPS approach to implement OPF addressing also the interoperability issues.
