The overall significant growth in electrical energy generation will increasingly be based on a large number of decentralized and fluctuating photovoltaic and wind power plants.[i] The combination of a large number of different fluctuating feed-in systems with systems that can be easily planned and controlled leads to a high degree of complexity in both the planning and operation of electrical networks. In addition, the coordination and communication effort between the actors concerned increases.
Interactions within the energy distribution network and between the distribution and transmission network levels will therefore increase due to the complex and adaptive behaviour of its network participants. This increases the demands on network operations management and the cross-voltage level management of SDL[ii]. This leads to increasing demands on the scope and resilience of the digital transformation of the energy system as well as to new requirements on the economic and legal framework of the future electrical power supply system[iii]. At the same time, the digital transformation creates new opportunities for the design, provision and coordination of the SDL required in the new system design.
For these reasons, from a technical, economic and regulatory perspective, the framework and options for the deployment of SDL urgently need to be further developed and adapted to future requirements.[iv]

In this joint project, the existing Ancillary services are being further developed for future power grids and adapted to the changed requirements and possibilities resulting from the digital transformation and advanced energy system transformation. In addition, new methods and systems for the provision of required and invoiced SDL are designed and evaluated. Together, solutions for the safe operation of future power grids with a high proportion of decentralized generation plants are being developed and tested. The OFFIS part mainly focus on deploying SDL in distribution networks in flexible manner by leveraging information technology.
