“…Multiple use cases for TSO-DSO coordination are analyzed in [2] to identify information that is missing in the CGMES. Since the paper is attempting a general approach to address a range of different use cases, CIM would not be sufficient without several extensions.…”

“…As proposed in [2] the equivalents package can be used to exchange the network equivalent models. However, while [2] proposes to extend the CGMES with validity time information and status information to achieve a more flexible dynamic behaviour, this is avoided in our simpler approach by using a periodic update interval. Considering that the typical current grid operation use fixed update intervals of for example one hour or 15 minutes, this is a sufficient solution which can match the operation with available planning information.…”

“…This implies that in between simplifications of the DSO grid has to be carried out with utmost care and tailored In addition, the experiments demonstrate that this can be achieved within the existing CIM specification using a subset of the CGMES together with ICCP. Hence, for this use case there is no need for extension such as those proposed in [2], if we use the pragmatic approach considered here with a periodic exchange of well-defined information elements.…”

“…Traditionally the non-renewable based conventional generation connected to the transmission system has been providing inertia and system services to the power system. As the conventional generation phases out, while being replaced by DERs connected in the distributions system, TSOs will start to look for ancillary services from distributed energy resources connected in the DSO network [2]. Hence, operational level coordination between TSO and DSO will be more frequent and is going to be characterized by large amount of network model, measurement data as well as control signals exchange in real-time.…”

<p>As conventional power generation units are being replaced with distributed energy resources, operational practices such as voltage regulation and congestion management are expected to be challenging. To address these challenges, regular and automated inter-control centre operational coordination will be needed between Transmissions and Distributions System Operators (TSO and DSO). In this study, the data exchange required for the near-real-time operational coordination is investigated for a reactive power management use case. A realistic ICCP/TASE 2 protocol is implemented in laboratory environment where the physical network is simulated in a real-time simulator while optimal set-points are communicated from the control centers to simulated assets being communicated through the IEC 60870-5-104. In addition, the sufficiency of the Common Information Model (CIM) and Common Grid Model Exchange Standard (CGMES) is evaluated for TSO-DSO network data exchange. The results from the cyber-physical test setup show that the detailed DSO grid model knowledge by the TSO results in lower system losses. Such data can be difficult to prepare, exchange and compute. However, results show that simplified equivalent models can be acceptable if they are properly tailored to the specific use case. The experiences from the CIM implementation with the CGMES profile are found out to be sufficient for such operational data exchange.</p>

Towards Flexible Distribution Systems: Future Adaptive Management Schemes

During the ongoing evolution of energy systems toward increasingly flexible, resilient, and digitalized distribution systems, many issues need to be developed. In general, a holistic multi-level systemic view is required on the future enabling technologies, control and management methods, operation and planning principles, regulation as well as market and business models. Increasing integration of intermittent renewable generation and electric vehicles, as well as industry electrification during the evolution, requires a huge amount of flexibility services at multiple time scales and from different voltage levels, resources, and sectors. Active use of distribution network-connected flexible energy resources for flexibility services provision through new marketplaces will also be needed. Therefore, increased collaboration between system operators in operation and planning of the future power system will also become essential during the evolution. In addition, use of integrated cyber-secure, resilient, cost-efficient, and advanced communication technologies and solutions will be of key importance. This paper describes a potential three-stage evolution path toward fully flexible, resilient, and digitalized electricity distribution networks. A special focus of this paper is the evolution and development of adaptive control and management methods as well as compatible collaborative market schemes that can enable the improved provision of flexibility services by distribution network-connected flexible energy resources for local (distribution system operator) and system-wide (transmission system operator) needs.
