Power System modelling

  • A balance model for Denmark 2030

    Bengt J. OlssonTwitter: @bengtxyz  The balance model described in this post is used to model the behavior of a future power system for Denmark in 2030. The model is based on production/consumption numbers proposed by “Denmark’s Climate and Energy Outlook 2020” (DCEO) for 2030. The idea with the simulation is to simplify the model as far…

  • Balancing with hydrogen instead of hydro?

    Bengt J. OlssonTwitter: @bengtxyz  An interesting “gedanken” experiment would be to have a scenario where hydro power in Sweden is exchanged with green hydrogen power for balancing the power supply and demand. After all, not many countries are blessed with the natural resources in form off hydro power that we have in Sweden and Norway. In…

  • Power balance in Sweden 2020-2021

    Bengt J. OlssonTwitter: @bengtxyz  The balance model described in this earlier blog post is very versatile for testing and evaluating different power mix scenarios. In this post we will return to the year of the included wind data which is kind of key to the model. We will look at some aspects of the model applied…

  • SvK EF 286 TWh 2045 revisited

    Bengt J. OlssonTwitter: @bengtxyz  The original blog post on modelling and simulating a future Swedish power system describes a balance model and its application on a scenario depicted by Svenska Kraftnät, the Swedish TSO. Please refer to that blog post for an understanding of the model. In this blog post we will look at the same…

  • Solar vs wind power in Sweden 2030

    Bengt J. OlssonTwitter: @bengtxyz  Solar power installations are increasing at an exponential rate in Sweden right now. And what it is it not to like about solar power? Provides free energy right into your house or apartment, and if you can’t use the energy just sell it back to your utility company at spot prices. With…

  • Wärtsilä’s concept for base load power generation

    Bengt J. OlssonTwitter: @bengtxyz  In an article in the Finnish daily newspaper Helsingen Sanomat, a concept for producing a guaranteed base load power, corresponding to a large nuclear reactor, is presented. Unfortunately there is no reference to a report, but the context seems rather clear from the summary table: So the basic assumption is that with…

  • Intermediate 2030 power system scenario

    Bengt J. OlssonTwitter: @bengtxyz  In this post we will analyze a 2030 scenario that is 8 years away from now. The demand is captured from the “Scenarioanalys 2050” report1. In the figure below (from that report) it can be seen that the consumption 2030 will be about 195 TWh out of which 30 TWh are used…

  • Here comes the sun

    Bengt J. OlssonTwitter: @bengtxyz  I finally got around to add solar (PV) power to the balance model. As I suspected, this did not significantly change the conclusions that could be drawn from the wind-only model. But of course, for the sake of completeness, we should also include solar power in the balance model. Since I couldn’t…

  • What if Sweden had no hydro power in 2045?

    Bengt J. OlssonTwitter: @bengtxyz  From the previous two posts we have a balance model of Swedens power system, with and without a deficit energy store. It models a scenario depicted by Swedish TSO Svenska Kraftnät (SvK) as “Renewable Electrification” (“Elektrifiering Förnybart”; EF) that comprises 286 TWh consumption by 2045, out of which 85 TWh are for…

  • Balancing energy store (2/2)

    Bengt J. OlssonTwitter: @bengtxyz  In the previous post, for the 286 TWh wind power scenario we concluded among others that we would get a deficit of about 0.93 TWh per year, even after significant flex from hydrogen production. In this post we will enhance the simulation by adding a separate balancing energy store that may resolve…
