Top-Down modelling of distributed flexibility for usage at higher voltage levels

Abstract

The number of units on both the generation and consumption sides of the electric sector continue to increase over the course of the energy transition, especially at lower voltage levels. Many of these systems (e.g. heat pumps or battery storage systems) offer the potential to provide flexibility, although the low power level of single units limits their network effect when operated individually. By modelling aggregations of the respective flexibility type, a remarkable flexibility potential can be made available for the grid operator to use for e.g. congestion management at a point upstream.
