TSO-DSO Interactions: Challenges and solutions
Nisheeth Singh SPECS GmbH, Switzerland
5/13/19 Nisheeth Singh EPCC 2019 , Session 1 1
Driving factors for increased TSO-DSO interaction
• Environmental concerns and policy • Situation in Europe• Technical
• Command and control• Data Analytics• Affordable communication• Advanced IEDs including WAMs
• Penetration of Renewable / distributed energy source• Storage E-Vehicle• Intermittent source: Roof top solar plants, wind
• Data Flow for market and operations

• Local scale
• Distributed resources
What’s really in the CEP?Ø EU DSO Entity to give a European voice and weight to the DSOsØ DSOs empowered to access flexibilities services, define new products and new rulesØ DSOs are recognized as legitimate actors for data managementØ DSOs are to hold the pen for future network codes
• Prosumers
Cybersecurity
Data exchange and interoperability
Rules for non-discriminatory, transparent provision of non-frequency ancillary services
Demand response
Setting the scene: DSOs in EuopeComparing 43 TSOs vs. 2700 DSOs in Europe
About 2200 are below the 100 K threshold, and thus exempted from unbundling

A cooperation creating value for the customer
DSO-TSO Cooperation
Extended data exchange, enhanced observability and controllability, right
level of transparency
Enable efficient use of flexibilities for congestion management on the grids and for balancing of the
power system
Facilitating markets and designing products for flexibility together with
customers, aggregators, suppliers, traders, DSOs,
