High-Precision Solution for Croatian Energy Management System

Croatia's high-precision energy management relies on an integrated EMIS, advanced modeling of renewable energy sources, and multi-objective optimization for system flexibility and efficiency. Energy Management Information System (EMIS)The EMIS is the cornerstone of Croatia's energy management strategy, enabling continuous data collection, monitoring, and analysis of energy and water consumption in public sector buildings. It automates reporting, reduces administrative burden, and ensures data credibility and accuracy.

The system allows disaggregation of energy consumption by building type, providing real-time insights into energy usage patterns and enabling targeted efficiency measures.

S has been successfully adapted in other countries, demonstrating its scalability and robustness. Integration of Renewable Energy Sources (RES)Croatia's energy system incorporates solar, wind, and hydro power across multiple locations, including Zagreb, Split, Rijeka, and Osijek. Due to the stochastic nature of RES, energy storage solutions such as hydro accumulation, chemical batteries, ultra-capacitors, and heat/cold storage are integrated to balance supply and demand.

Electric vehicles (EVs) are also leveraged in Vehicle-to-Grid (V2G) mode, providing additional storage capacity and enhancing system flexibility.

Multi-

Objective Optimization and System PlanningHigh-precision solutions employ a two-level multi-objective optimization approach to design the Croatian Energy System (CES) for 2015–2050. This method considers both temporal and geographical dimensions: Temporal dimension: Balances energy production and consumption across daily, seasonal, and annual cycles, accounting for surplus and shortages. Geographical dimension: Optimizes energy transmission from production sites to demand centers, requiring robust high-voltage networks and potential AC-to-DC conversion for long-distance transfer.

The optimization ensures efficient use of conventional and renewable energy sources, maintaining reliability under variable weather conditions and fluctuating demand. Regulatory and Strategic AlignmentCroatia's energy management aligns with the Integrated National Energy and Climate Plan (NECP), targeting decarbonization, energy efficiency, and increased RES share by 2030. The system supports greenhouse gas reduction, compliance with EU regulations, and preparation for carbon neutrality by 2050.
