10 Challenges in the transition from a passive distribution grid to an integrated, smart system, e.g. in Germany Growing complexity in grid operation Interdependencies of market roles and power/ ICT convergence Actors and objectives in grid operation From single device to system testing Some open questions

11 Growing Complexity Type Number of units Installed power PV in Germany about ca. 36 GW Wind in Germany about ca. 35 GW Growing number of generators Growing variability of power production Growing number of actors Grid operator, energy supplier, ESCOs (metering service, load aggregators, generation aggregators, ) Prosumers, demand-side-management Growing number of storage systems (large scale and household scale, electric vehicles) Growing number of automatic control strategies and functionalities Bi-directional power flow

12 Interdependencies in power system control System control by Market mechanisms Interaction between market and direct actions Emergency actions (German BdEW-Ampel )

19 Multiple actors with possible divergent objectives

20 Classical approach: component and field testing Component testing But how can interaction and interoperability testing be done? Field testing Testing under normal operation with given use patterns Testing of a variety of use patterns possible only for a variety of different test locations very costly and time demanding Testing of failures or extreme situations is difficult, if not impossible

21 Testing environments Use case XY Simulation Laboratory testing Performance Training simulator Field test Requirements System Subsystem Component

22 Use Case Classification Possible classification criteria Power rating and time scale/ dynamics Interoperability Technical communication (syntax), general communication (semantic/ language) Power network influence Required modelling Devices, communication/ communication path, needs of model validation Required specification Level of detail Slide 22 W. Heckmann, Power System Testing, DERlab/SIRFN Online Workshop,

23 What do you think are relevant use cases for system operation in an integrated, smart grid? Power rating 10/ 100/ 1000 kw Time scale an dynamics a few cycles up to 2000 ms 1 to 10 minutes 10 minutes to several hours Interoperability Technical communication (syntax) general communication (semantic/ language) Power network influence Slide 23 W. Heckmann, Power System Testing, DERlab/SIRFN Online Workshop,

24 Use case: Provision of flexibility to the grid Grid supporting control of generation or load for frequency or voltage support Example from FNN Use Case Grid Supporting Control (non-regulated)

25 Use case: massive OLTC MV-LV transformer deployment Deployment of OLTC MV/LV transformers, electrically near Voltage band (±10%) usage without OLTC MV/LV transformer

26 Use case: massive OLTC MV-LV transformer deployment Deployment of OLTC MV/LV transformers, electrically near Voltage band (±10%) usage with OLTC MV/LV transformer

27 Use case: Interdependent functionalities Dynamic voltage support and network protection/ fault detection Are the DSOs happy to support the TSOs? Congestion Management and aggregated negative/ positive reserve Weather/ generation forecast and flexibility request
