Impact of DER integration on the cyber security of SCADA systems – the medium voltage regulation case study

L’articolo illustra le possibili modifiche architetturali e gli scambi informativi richiesti dalla funzione di controllo della media tensione, supponendo che questa funzione sia posizionata a livello della rete di stazione AT/MT. Il documento discute i possibili scenari di rischio cyber-power e le contromisure necessarie per la loro mitigazione.

The operation of active distribution grids with high penetration of Distributed Energy Resources, connected to Medium Voltage bars and feeders, requires theimplementation of new Medium Voltage regulation functions. Assuming that this control function is best positioned in the primary substations of the controlhierarchy, the paper presents the architectural changes occurring at both the centre and the substation control levels. Possible cyber risk scenarios and mitigation countermeasures of the new SCADA architecture are discussed, in compliance with the IEC communication standards and the IEC/NIST cyber security technical recommendations related to the smart grid sector.
