Item Cost-Benefit Analysis of TSO-DSO coordination to operate flexibility markets(2019-06) Madina, Carlos; Riaño, Sandra; Gómez-Arriola, Inés; Kuusela, Pirkko; Aghaie, Hamid; Jimeno, Joseba; Ruiz, Nerea; Rossi, Marco; Tecnalia Research & Innovation; POWER SYSTEMS; SISTEMAS FOTOVOLTAICOSThis paper presents the outcome of the cost-benefit analysis (CBA) for the different alternatives defined in the project SmartNet for the coordination between transmission system operators (TSOs) and distribution system operators (DSOs). The CBA compares five coordination schemes in three countries (Italy, Denmark and Spain) on the basis of several economic indicators. On top of them, it also calculates some non-economic indicators to enrich the analysis. The main results for the Italian and the Spanish cases are presented in this paper.Item Optimised TSO-DSO Coordination to Integrate Renewables in Flexibility Markets(IEEE, 2019-09) Madina, Carlos; Kuusela, Pirkko; Rossi, Marco; Aghaie, Hamid; Gomez-Arriola, Ines; Riaño, Sandra; POWER SYSTEMS; SISTEMAS FOTOVOLTAICOSThe necessary energy transition to decarbonize power systems is leading to increasingly important challenges for the operation of power systems. On the one hand, the intermittent nature of renewable generation requires system operators to procure ancillary services in larger volumes than in the past. On the other, the growing penetration of medium- and small-scale, flexible demand and storage systems in distribution networks could potentially offer network services, if they are aggregated effectively and there is an appropriate coordination between transmission system operators (TSOs), distribution system operators (DSOs) and aggregators. Therefore, an important topic to be analysed is whether distributed energy resources (DER) can replace traditional generation in the provision of ancillary services (AS), how this replacement will affect the system operators’ roles and how to improve the coordination between TSOs and DSOs. This paper shows the results of the cost-benefit analysis (CBA) performed within the project SmartNet to assess the advantages or disadvantages of different TSO-DSO coordination schemes, as well as the follow-up activities to be carried out in the project CoordiNet.
