Monitoring LV Prosumers Operation Using Hilbert - Huang Method

The new technologies and regulation initiatives favoring local energy communities, together with larger - scale deployment and operation of microgrids have revealed that the rigid contractual link (intermediated by various forms of utilities) between traditional electricity generation and (mostly passive) customers is getting weaker and weaker. We face a paradigm shift where final users are becoming prosumers with generation and storage capacity and look for solutions enabling flexibility to enter a market which is also evolving. In this paper we focus on the capacity of enhancing prosumer flexibility by non-intrusive analysis of both demand - and generation patterns identified in the current signals at point of connection. A version of the Hilbert-Huang method is applied to obtain a time-frequency representation from which information enabling prosumers' efficient operation can be extracted.
