DSOF

We have published the first Distribution System Operability Framework (DSOF), an assessment of technical issues facing Distribution Network Operators (DNOs) as they become Distribution System Operators (DSOs). We are actively looking for future technical and commercial issues which could impair our ability to operate and maintain our networks efficiently whilst developing capacity for new connections. Raising awareness of these issues will enable us to seek new solutions and manage them efficiently and cost effectively.

Publishing insights on a variety of different topics affecting electrical networks will help the industry raise the profile of these technical issues. We will share our learning and discussions with other DNOs and Independent Distribution Network Operators (IDNOs), with a particular focus on collaboration through the ENA Open Networks programme.

Issues affecting electrical distribution networks can also affect electricity transmission networks and other energy vectors. We will work with National Grid as the GB System Operator, and other parties affected by these issues to further understand the impacts as they develop.
As we move towards becoming a DSO, we will increasingly work with customers to access resources and services that they may have at their disposal and which may benefit the network. Opening this dialogue at an early stage will enable us to work with customers to economically provide whole system solutions as they develop future Distribution Energy Resources (DER).

In the DSOF we consider a range of issues from network design through to real-time network operation. A key theme throughout the DSOF is the growing role of data capture and analysis in distribution system operation. The last ten years have seen unprecedented developments in distribution networks. The growth of distribution-connected generation has driven a major shift in Great Britain’s generation mix towards renewables. Meanwhile, advances in control systems and power electronics are providing us with alternatives to conventional reinforcement when managing demand growth and providing new connections.

We intend to review each article periodically, and publish updated articles individually as the issues and their potential solutions develop. We also intend to continue researching emerging issues and publish new articles on them in future.
