Current State of Energy Planning and Modelling of Integrated Energy Systems - a Review

In order to tackle the anthropogenic climate change through the reduction of greenhouse gases, energy system’s planners are looking at cleaner and cheaper ways of energy supply in the future energy systems. Energy transition, from fossil fuel-based systems with dispatchable production satisfying the consumption to variable production from renewable energy and responsive variable consumption, is on the way. Various scientific groups all over the world have taken up the challenge of modelling such energy transition and configurations of future energy systems. Modelling approaches differ in the time unit of calculation, geographical reach and system boundaries and limitations. According to the majority of the research, future energy systems include strong synergies between the variable production of electricity and sectors of consumption such as heating, cooling and transport systems, which have the additional benefit of decarbonisation of all sectors. Such energy systems can be called integrated energy systems. In the present research, a comparison of approaches and relevant results from recent practice has been made, distinguishing these approaches according to their treatment of synergetic effects between the sectors, use of demand response technologies, storage technologies and time frame for calculations. Also, further distinctions are made in accordance with the treatment of efficiency of the energy system’s configuration, such as calculation of excess of electricity produced from variable energy sources or energy return on investment. The resulting overview shows the trends in approaches and most relevant research results for the long-term energy planning and modelling of the future integrated energy system’s configurations in terms of systems integration and time scale of calculation.
