Item Adopting smart meter events as key data for low-voltage network operation(2017-10-01) García Prado, Jesús; González, Ana; Riaño, Sandra; SISTEMAS FOTOVOLTAICOSA pioneering analysis of smart meter events aimed to enhance low-voltage (LV) network operation by the detection of voltage deviations, repetitive incidents or even outage prevention is presented. The main challenge of using smart meters events is the vast amount of data collected: the average of events gathered in an area per day is around 40% higher than the number of smart meters installed. To transform this huge quantity of information in network improvements, a set of strategies have been undertaken. The core purpose of this analysis is to establish a more rational and automated processing of smart meter events, aimed to embrace them as key information for network operation.Item Scenario-based approach adopted in the ELECTRA project for deriving innovative control room functionality(2017-10-01) Marinelli, Mattia; Heussen, Kai; Prostejovsky, Alexander; Bindner, Henrik W.; Catterson, Victoria M.; Merino, Julia; Tornelli, Carlo; Tecnalia Research & InnovationHere, the authors analyse the operator point of view of the Web-of-Cells concept defined in the EU project ELECTRA, by identifying operator tasks into the supervision of a highly automated power system, and the information requirements to facilitate appropriate operator situation awareness. The study outlines the methodology adopted, which is based on the cognitive work analysis framework, to provide an overview of the most interesting scenarios and to summarise the requirements analysis results. In order to derive required control room functionality, a set of relevant control room scenarios have been identified based on the Web-of-Cells control concept. The authors considered scenarios that challenge traditional control schemes, scenarios that caused major failures (i.e. blackouts), and scenarios that can be expected to appear in the future. For each scenario, information concerning network layout, triggering events, physical constraints, manually/automatic operations, operators' tasks, and relevant analytics have been analysed.Item SmartNet: H2020 project analysing TSO–DSO interaction to enable ancillary services provision from distribution networks: H2020 project analysing TSO- DSO interaction to enable ancillary services provision from distribution networks(2017-10-01) Migliavacca, Gianluigi; Rossi, Marco; Six, Daan; Džamarija, Mario; Horsmanheimo, Seppo; Madina, Carlos; Kockar, Ivana; Morales, Juan Miguel; POWER SYSTEMSThis study presents an overview of the results obtained during the first year of the SmartNet project, which aims at comparing possible architectures for optimised interaction between transmission system operator (TSOs) and distribution system operator (DSOs), including exchange of information for monitoring as well as acquisition of ancillary services (reserve and balancing, voltage regulation, congestion management), both for local needs and for the entire power system. The results concerning TSO-DSO coordination schemes, market design and information and communication technology (ICT) architectures are shown along with the layout of the three technological pilot projects.
