A new platform for testing TSO-DSO coordination schemes 12th IEEE PES PowerTech Conference A new platform for testing TSO-DSO coordination schemes Marco Rossi (RSE)

Comparison of the national cases in a simulation environment and laboratory testing Development and validation of a future scenario (2030) and simulation environment in order to reproduce the TSO-DSO interactions in the three national cases Elaboration of ad-hoc Cost Benefit Analysis methodology and selection of the TSO-DSO interactions with the highest potential Implementation of the simulation environment in the laboratory in order to test real equipment aimed at contributing in TSO-DSO interactions

2030 EU reference scenarios 2030 Scenario Data European reference scenarios are processed in order to generate the system configurations and data to be used in simulation and laboratory studies 2030 EU reference scenarios Processing Simulation data

2030 Scenario Data European reference scenarios are processed in order to generate the system configurations and data to be used in simulation and laboratory studies

2030 Scenario Data Geographical allocation of the energy resources expected for 2030 Population growth Renewables expansion Exploitation of new electrical devices Industrial development

2030 Scenario Data Mapping of the geographical information on the electricity network Distribution network

Simulation blocks Physical layer Simulates the physical transmission and distribution networks, operation and connected devices Bidding and dispatching layer Converts flexible devices status and parameters into bids and distributes power set-points resulting from the market Market layer Runs the market clearing algorithms on the basis of the received bids and network constraints

Simulation diagrams A B C D1 D2

Simulation diagrams Coordination schemes with common market in which transmission and distribution resources participate A. Details on the exchanged information: used for the design of the ICT network and calculation of ICT costs (processed later by CBA)

Simulation diagrams C. Transmission C. Distribution Coordination schemes with separated markets: one for transmission and one for distribution resources C. Transmission C. Distribution

Simulation approach The simulation will be performed by considering the selected scenario (how Italy, Denmark and Spain will evolve in 2030). Variations to the average scenarios will be introduced in order to evaluate the sensitivity of simulation results to scenario variations

Calculating the costs and the benefits at system level KPIs Lifecycle costs Overall system social welfare CO2 emissions System reliability Extra costs due to distribution investments Extra costs due to market power Socio-environmental costs of new lines Social welfare split (winner/loser zones and stakeholders with weighing) RES curtailment costs CO2 prices interval up to change merit order Risk driven vs. “social” rates for the ROI Core elements (typical) Experimental items (innovative) Sensitivity factors (enriching)
