Concepts for integrating flexibilities into dynamic load management for residential and non-residential buildings

This article presents the concepts of two add-on systems for smart grids, which aim to integrate new actuators, such as the charging infrastructure for electric vehicles, electric heat pumps, and battery storage systems, as flexibility options for dynamic and market-oriented network congestion management. The developed concepts focus on the regulated sector of the grid operator (the ElCiN project's focus) and on the free-market sector of the energy customers (the InFleX project's focus), taking the requirements of both sectors into account. The overall concept developed in the course of the EICiN project, which implements the cellular approach of the VDE (VDE Ver-band der Elektrotechnik Elektronik Informationstechnik e. V, Zellulares Energiesystem: Ein Beitrag zur Konkretisierung des zellularen Ansatzes mit Handlungsempfehlungen, https://www. vde.comiresource/blob/1884494/98f96973frdba7077765.4d0f40c179e5/studie-zellulares-energlesystern-datapdt 2019), enables a fully automated and market-oriented network congestion management. Data exchange between the regulated sector and the market sector was defined, which can integrate individual new grid actuators as well as grid actuators that are pooled and potentially optimized in cells into the network congestion management. The InFleX project deals with enhancing the flexibilities for (non) residential buildings and their energetic optimization as well as with providing flexibilities for smart grids. Both developed concepts and the systems resulting from them can be combined to create an overall system. Such a system implements the cellular approach of the VDE without disregarding the requirements and interests of the grid operator and the customer.
