Smart Grid Power Management Interface for Use of short-term Flexibility

Abstract

The high importance of Demand-Side-Management for the stability of future smart grids is consensus among a wide spectrum of energy market participants and within the research community. While it is accepted that Demand-Side-Management will yield positive contributions, it remains challenging to identify, access, and communicate available flexibilities to the flexibility managers in order to determine impacts and choose temporarily required demand-side flexibility to ensure system stability. In this paper we introduce a methodology to determine and communicate local flexibility potential of end-users to flexibility managers for short-term access. The presented approach achieves a reliable calculation of flexibility, a standardized low bandwidth data aggregation, and communication. With the integration into an existing system architecture the general applicability is outlined with a one end-user use case. The approach yields a transparent short-term flexibility potential within the flexibility manager system.
