Abstract

Regional transmission and distribution challenges has evolved and changed a lot in recent years.
Four contradictory influences increasingly affected the operations of Slovenian and Croatian
electricity systems. Regional electricity systems experienced increasing support of RES integration
to meet the EU targets, a lower electricity consumption due to the economic crisis, a growing lack
of centralized electricity production for electric system support and the high interconnectivity
between the neighboring control zones. TSOs and DSOs observed growing network overvoltage
issues as well as a decrease in secondary reserve capacities. Such situation starts to impact national
and regional renewable integration targets affecting the security of supply at European level.
SINCRO.GRID joint investment project addressed the above-mentioned issues in a sustainable
manner. Such cross-border systemic approach will bring synergetic benefits. It will enable an
acceptable level of security of operation for at least the next ten years hosting levels of RES in line
with the trends foreseen to reach the 2030 targets safely. The project is going to integrate new
active elements in the transmission and distribution grids. It leans on the following main pillars:
deployment of six compensation devices, deployment of advanced dynamic thermal rating (DTR)
systems, deployment of electricity storage systems, integration of distributed renewable generation
(DG) and deployment of a virtual cross-border control center (VCBCC). A key aspect of the
SINCRO.GRID project lies in the synergy brought by the simultaneous innovative deployment of a
portfolio of mature technology-based solutions bring high benefits and positive externalities for the
region and European Union.
