The SINCRO.GRID project is a smart grid investment project of European importance in the territory of Slovenia and Croatia. Its conformity with EU policies in the area of smart grids having now been proven, the project is being co-financed by the European Union.

Goals and positive effects of the project

  1. Establishing operating conditions that will provide for increased generation from renewable energy sources and dispersed generation, as well as greater potential for their penetration into distribution and transmission grids in Croatia and Slovenia;
  2. Implementing one of the important smart grid technologies – increasing transfer capacities by dynamic monitoring of overhead transfer capacities (DTR), which will provide for better utilisation of the existing transmission grid and higher transfer capacity without the construction of new overhead lines;
  3. Ensuring technical control of dedicated and non-dedicated sources of reactive power by optimisation based on national and international cooperation between transmission and distribution system operators;
  4. Establishing control and centralized management of generation from renewable energy sources and system variables on the high-voltage and medium-voltage networks of Croatia and Slovenia;
  5. Relieving local power flows in the 110 kV grid and providing alternative ancillary services (secondary regulation) in a range of up to 12 MW;
  6. Increasing network capacities for energy transmission by the use of real-time control of operational limits of network elements will enhance new investments needed for reliable operation;
  7. Improving the observability of distribution and transmission networks by the use of advanced forecasting tools for assessment of operating limits (SUMO), and pooling the information of distribution and transmission systems, which will facilitate operation of the transmission network and reduce future needs for ancillary services;
  8. Improving observability of renewable energy sources, which will impact the operation of the transmission and 110 kV grids on an international level;
  9. Improving the communication platform for DSM tertiary reserve to ensure more transparent cooperation between reserve providers and transmission system operators;
  10. Increasing cross-border capacities by real-time control of operational limits of network elements;
  11. Resolving issues related to inadequate voltage profiles on the transmission systems of Croatia and Slovenia;
  12. Ensuring an additional 5 MW of tertiary reserve by establishing a joint communication platform for DSM, which will provide transmission system operators with more accurate and accessible data.
