Implementation of a Coordinated Voltage Control Algorithm for a Microgrid via SCADAas-a-service approach

International audienceThe massive penetration of distributed renewable energy resources (DRES) at low voltage distribution network poses challenging power quality issues. Coordinated voltage control is necessary in microgrid with high DRES rate to keep the voltage in required range and to optimize the grid performance. This paper presents the implementation of a coordinated voltage control algorithm on a real world microgrid via SCADA-as-a-service (SCADA-aaS) method. The SCADA-aaS approach provides the interoperability framework for the network operators to provide their CVC algorithm to microgrid owners or to implement a third party CVC. This real world implementation demonstrates the feasibility of the SCADA-aaS approach. Experiences and lessons learned from the implementation are discussed

CIM compliant multiplatform approach for cyber-physical energy system assessment

International audienceWith high penetration of distributed renewable energy resources along with sophisticated automation and information technology, cyber-physical energy systems (CPES, i.e. Smart Grids here) requires a holistic approach to evaluate the integration at a system level, addressing all relevant domains. Hybrid cloud SCADA (Supervisory, Control And Data Acquisition), allowing laboratories to be linked in a consistent infrastructure can provide the support for such multi-platform experiments. This paper presents the procedure to implement a CIM (Common Information Model) compliant hybrid cloud SCADA, with database and client adaptive to change in system topology, as well as CIM library update. This innovative way ensures interoperability among the partner platforms and provides support to multi-platform holistic approach for CPES assessment

Cross-infrastructure holistic experiment design for cyber-physical energy system validation

International audienceStrong digitalization andshifting from unidirectional to bidirectional topology have transformed the electrical grid into a cyber-physical energy system, i.e. smart grid, with strong interdependency among various domains. It is mandatory to develop a comprehensive and holistic validation approach for such large scale system. However, a single research infrastructure may not have sufficient expertise and equipment for such test, without huge or eventually unfeasible investment. In this paper, we propose another adequate approach: connecting existing and established infrastructures with complementary specialization and facilities into a crossinfrastructure holistic experiment. The proposition enables testing of CPES assessment research in near real-world scenario without significant investment while efficiently exploiting the existing infrastructures. Hybrid cloud based architecture is considered as the support for such setup and the design of crossinfrastructure experiment is also covered
