Case Studies

In 2005-2007, the EnergyPLAN model was used in a project to investigate if Compressed Air Energy Storage (CAES) would be a feasible technology in the Danish Energy System. The project was conducted in a collaboration with the Department of Mechanical Engineering at the Technical University of Denmark and the company DONG Energy and was funded by the Danish TSO Energinet.dk....

n this project, scenarios were developed for a transition of the Danish city Frederikshavn to become 100% fuelled by renewable energy sources. The project investigated the potential of locally available renewable energy sources, the possible technologies which make use of these, the potential energy savings, the potential transitions to district heating, as well as the problems of load balancing associated...

In 2000-2001, the EnergyPLAN model was used in the contributions of Aalborg University to the work of a Danish expert group formed by the Danish Energy Authorities to analyse the excess electricity production problem arising from large-scale integration of CHP and wind power. The results were first published in a report in Danish and subsequently, they formed the basis for...

In the autumn of 2006, the EnergyPLAN model was used for the condensed analyses of the Energy Year 2006 of IDA. The outcome of the Energy Year is an energy plan for the year 2030. The main report and background report (in Danish) can be downloaded here.   The following results of the EnergyPLAN systems analyses can be downloaded:   Reference 2030 (The “business-as-usual”...

In this report, technical energy system analysis, effects on fuel consumption and emissions of greenhouse gases, as well as socio-economic consequences have been calculated with the EnergyPLAN model. In addition, the report analyses employment effects, technology export potential and health effects. The report has been prepared by Brian Vad Mathiesen, Henrik Lund andKenneth Karlsson.   Greenhouse gas mitigation strategies are generally considered costly...

In the PhD dissertation “Integration of fluctuating renewable energy using energy storage”, David Connolly used the EnergyPLAN model to analyse pumped hydroelectric energy storage (PHES). After completing an extensive review of existing energy tools, EnergyPLAN was chosen for this research due to its flexibility, transferability, and because it considers the entire energy system i.e. electricity, heat, and transport. Once EnergyPLAN was chosen...

This article presents a methodology of showing the rate of integration of specific renewable energy sources (RESs) into the electricity supply system. The methodology is used on large-scale integration of wind, photo voltaic and wave power into a future Danish reference energy system. The possibility of integrating RES into the electricity supply is expressed in terms of the ability to avoid excess...

Link to the Journal Paper   Across the world, energy planners and transmission system operators are faced with decisions on how to deal with challenges associated with high penetration levels of intermittent energy resources and combined heat and power (CHP). At the same time, distributed plant operators are eager to reduce uncertainties related to fuel and electricity price fluctuations. These...

Link to the Journal Paper   Large-scale sustainable energy systems will be necessary for substantial reduction of CO2. However, large-scale implementation faces two major problems: (1) we must replace oil in the transportation sector, and (2) since today’s inexpensive and abundant renewable energy resources have fluctuating output, to increase the fraction of electricity from them, we must learn to maintain...
