Special event of the project „Investigating energy transition pathways – interrelation between power-to-X, demand response and market coupling“– INTERENERGY, funded by the Croatian Science Foundation under the project number IP-2019-04 9482, will take place at 9:00, on Thursday, October 14th 2021 in the ROOM A. Special event chair and project leader is prof. Neven Duić from the University of Zagreb, Faculty of Mechanical Engineering and Naval Architecture.
The INTERENERGY project deals with interrelation between different power-to-x and demand response technologies and market coupling in the energy transition. Role of these technologies is investigated from the context of market coupling, which is already underway in the European Union. The key research question is how to achieve the balanced integration of different power-to-X and demand response technologies, determine their optimal mix and avoid unnecessary technological lock-ins. In order to achieve this, new H2RES energy planning tool is being developed to model the behaviour of power-to-X and demand response technologies. On this event, participants will have the opportunity to get detailed information about the new, open source long-term energy planning model, which is developed with particular emphasis on the technologies that can enable energy transition towards 100% RES-based energy systems. Also, a round table brings the prominent experts in the field of energy planning and modelling of energy systems together to discuss the progress of modelling of demand response and power-to-X technologies.

Already in 2050, but definitely by the end of this century, variable renewable energy sources (VRES) will supply most of the electricity, and significant amounts of energy consumed in heating, transport and industry sectors in the World. Therefore, the management of the variable electricity generation on the time scale under the year should be explored at various levels of energy system. Since the purpose of IAMs (including WILIAM) is usually the study of systems across large regions (global approach) and time scales of decades, some limitations have to be taken into account when trying to capture the effects of VRES integration into the energy sector, especially when such effects occur in times shorter than the time step of the model. When long-term energy planning is considered, it is of crucial importance to enable the spread of achievable configurations of the future energy systems, with particular attention given to the configurations based 100% on RES in primary energy supply (PES) and the ones that achieve operation with net zero greenhouse gas emissions (in other words, ability to model decarbonized energy systems).
The technical solutions that integrate larger amounts of RES are called flexibility options.
The reported results show that:
Some limitations are present within operational management part (frequency and voltage regulation) performed in the millisecond time range. This fast response is enabled via power electronics present in solar and wind power plants, in storage capacities - batteries, and in different devices on demand side. Such smart technology will significantly reduce the needs for overcapacities in future energy systems.

Special event of the project „Blue Energy Deployment Alliance“ – Blue Deal, funded by the European Regional Development Fund under the project number 5MED18_1.1_M23_072, will take place at 17:15, on Tuesday, October 12th, 2021 in the ROOM C. Special event chair is Hrvoje Mikulčić, PhD from the University of Zagreb, Faculty of Mechanical Engineering and Naval Architecture.
Blue Deal aims to increase transnational activity of innovative clusters and networks of the BE (Blue energy) sector, develop links and synergies between SME`s, public authorities, knowledge institutions and civil society and establish transnational and regional Blue Deal Alliances. In addition, scope of BLUE DEAL is to overcome current technical and administrative restrictions for BE deployment and define proper requirements and procedures to support decisions and guarantee compliance with regulatory, environmental and social constraints.
The Open days event will provide a valuable occasion to present project results in a non-technical way and to transfer project outputs to external organizations and to foster their replicability also beyond the end of the project.

Keywords: energy system, long-term planning, integrated energy system, power system modelling, electricity market and network analyses, energy atlas
Key topics that will be covered throughout the event:
Trends in energy policy indicate the necessary changes in the system of planning and drafting of the strategic documents and long-term energy and climate plans. Therefore, the plans within this project include research and development of a new integrated solution/expert system for the comprehensive drafting of long-term strategic energy and climate plans.
Through the cooperation of a scientific institute and an IT company, the project intends to develop an integrated solution that consists of a module for optimizing energy generation and consumption (and monitoring of the geolocation in the form of an energy atlas), a module for energy system planning and monitoring its security and vulnerability, as well as models for simulating changes in energy production and consumption (using new technologies, IoT...).
