REE N°3/2017 Z 105 LES MICROGRIDS (PARTIE 2) DOSSIER 2 Demand Side Management and Frequency Support within Microgrid A test bench to validate ICT architecture and to dump oscillations Thomas Morris, Da Wang, Gaspard Lebel, Catalin Gavriluta, Cedric Boudinet, Vincent Debusschere and Raphael Caire Researchers at Univ. Grenoble Alpes, CNRS, Grenoble INP, G2Elab, F-38000 Grenoble, France Climate change mitigation policies in microgrids commonly rely on the replacement of fossil fuel generation assets by Renewable Energy Resources (RES-E) and the introduction of storage units. Most RES-E are inter- mittent e.g. photovoltaics and wind power. These new gene- rating units induce challenges both in terms of stability and operational planning. As such, the research and industrial communities have made solutions to these issues a primary focus of inquiry since the mid 2000s. These rely in particu- lar on the deployment of information and communication technology (ICT) in power system assets, from the microgrid operation centre to the distributed energy resource (DER) units. Among the range of possibilities of microgrids, this article aims at developing a solution to handle the issue of frequ
