Flexibility definition for smart grid cells in a decentralized energy system

The networking of individual cells to form a decentralised network represents a possible approach for an energy system of the future, which is up to the challenges of the energy transition, such as stochastic electricity generation through renewable energies and the participation of many small producers. In this context, the sharing of flexibility in load profiles of cells requires a uniform definition to create a communication basis. This paper presents a generic description of flexibility by defining the latter as the set of all possible and permissible load profiles, taking into account dependencies between plants, technical constraints and maintaining energy balance within networks. The resulting solution space for load optimization problems, in form of the flexibility of a cell, can be described as a partial set of the RpT by derived constraints. The solution space is the keystone for further flexibility communication.
