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,…

  • Balance power contributors in the pan-European power system

    Bengt J. OlssonTwitter: @bengtxyz LinkedIn: beos With the increasing amount of renewable and weather-dependent power, firming or balancing power becomes more important. The question is: which are the major contributing balancing power sources in the pan-European power system? One way to measure the contribution from balancing powers in the power mix is to look at how they vary…

  • DIY – Cost Optimized Power System Model

    Bengt J. OlssonTwitter: @bengtxyz LinkedIn: beos When things get complicated, it is generally a good idea to try to simplify. A very complex system is the power system. Here’s a very simple balance model of a future Swedish power system modeled in Excel. The model uses “days” as the time unit to keep it more manageable, instead of…

  • 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…

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…
