Power System modelling

  • History of Adelsfors AB

    Adelsfors has a long history. It was started in 1987 by my father, Bengt G. Olsson, who had then divested his business, an electronics company named Xelex AB, in order to scale down his operations. Adelsfors AB became his platform for consultancy services within electronics design and similar activities. The name stems from a forgery,…

  • Scenarios for a Pan-European power network in 2050

    Bengt J. OlssonTwitter: @bengtxyz LinkedIn: beos What if Europe had a perfectly connected power system in 2050? With no transmission network limitations. This will be a long post, juggling large numbers, and with many assumptions that will make this investigation rather speculative. Anyway, you have been warned! What I have done is to use Energy Charts combined data…

  • Portugal 2040, power system according to the RMSA “conservative scenario”

    Bengt J. OlssonTwitter: @bengtxyz LinkedIn: beos BackgroundThe modelSimulationsDiscussionConclusions Background Following the same trend as many other countries, Portugal plans to increase its power generation to support more electrification, especially for hydrogen production to support a Power-to-X industry. In the so-called “conservative scenario” almost all the increase in power consumption targets the latter industry, while “classical” consumption is projected…

  • Denmark 2040 – RE and nuclear alternatives

    Bengt J.

Here is a simple model and simulation of how such a power system could behave under three years, based on wind and solar…

  • A simple model for comparing the costs of offshore wind power and nuclear power

    Bengt J. OlssonTwitter: @bengtxyz LinkedIn: beos IntroductionModelResultsConclusionsUpdate 2023-12-02 Introduction Offshore wind power and nuclear power are both complex and costly animals. Both are proposed to provide power in bulk to many regions. Just based on LCOE for each power type, offshore wind power has the upper hand based on a slightly lower LCOE in general. But what happens…

It is a continuation on the previous blog post that is in English. BakgrundKostnaderResultat och diskussionSammanfattning och slutsats Bakgrund I den tidigare bloggen undersökte jag fyra varianter för att tillgodose målet att kunna konsumera 300 TWh, varav 100 TWh…

  • Hydrogen sector-coupled model for Sweden 300 TWh

    Bengt J. OlssonTwitter: @bengtxyz LinkedIn: beos IntroductionModelScenariosResultsDiscussionConclusions Introduction Sweden’s future power system must accommodate up to 300 TWh of electricity consumption per year in the future according to many analysts. This is also often mentioned in the press. This is more than double the consumption of today which is about 140 TWh. Typical production today is around 170…

  • Optimized SWENS model for Germany

    Bengt J. OlssonTwitter: @bengtxyz LinkedIn: beos In the last blog post, I compared the Solar/Wind/Eco/Nuclear/Storage (“SWENS”) model with a similar model described by Ruhnau/Qvist (“RQ”), using as similar cost parameters and other presumptions as possible. While the RQ model is much larger in scope than my simpler SWENS model (remember, this is a blog, not a scientific paper……

  • Benchmarking SWENS model for Germany with Ruhnau/Qvist model

    Bengt J. OlssonTwitter: @bengtxyz LinkedIn: beos Oliver Ruhnau and Staffan Qvist (“RQ”) presents a very illuminating analysis of Germany’s storage need for a fossil free 540 TWh consumption scenario here (and here in a short Twitter thread). Basically, their power system is fueled with 700 TWh of renewable energy for a consumption of 540 TWh. The difference is…
