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

Framework requirement and Challenges

• Legal and commercial framework• Good communication infrastructure• Cyber Security, Data Privacy, • Clear command and control practices• Training for normal and perturbed conditions • Data Modelling and exchange• Technical Challenges associated with Distributed generation

• Lack of inertia/ Stability• Voltage control• Outage and Restoration

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,
