Concepts for flexibility use — Interaction of market and grid on DSO level

A variety of many new decentralised active grid users are integrated by distribution grids which offer flexibility options. Different concepts that enable distribution system operators to allocate available flexibility of active grid users in order to comply with local grid-related restrictions on the basis of interaction of market and grid are regarded in this paper. Common mechanism as well as crucial success factors are analysed. A proof-of-concept implementation is described as well as consequential challenges for distribution system operators and necessary adjustments of the regulatory framework that arise are pointed out.
