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,…

  • Welfare maximization in the European power system

    Bengt J. OlssonLinkedIn: beosX/Twitter: @bengtxyz  A short discussion on the principles for determining electricity prices and flows within the European power system. Basically, for each quarter of an hour an optimization problem, spanning the supply and demand in most of Europe, is solved by an algorithm named EUPHEMIA. This LinkedIn article provides a high level introduction to…

  • Är baskraften död – eller bara felprissatt?

    Bengt J. OlssonLinkedIn: beosX/Twitter: @bengtxyz  Är baskraften död? Nej men den missgynnas av en energy-only marknad som bara optimerar kostnader i driftstimman. Genom att betrakta baskraft som en gemensam nytta kan man styra mot ett mer kostnadsoptimalt system. Skriver om detta i energibranschens nättidning Second Opinion. Replik från professor Lennart Söder (KTH) 2026-02-13 “Professor Lennart Söder ifrågasätter…

  • Substituting fossil energy in the European power system – a contrafactual experiment

    Bengt J. OlssonLinkedIn: beosX/Twitter: @bengtxyz  In 2025, Europe consumed about 770 TWh of electricity produced from fossil fuel sources (excluding “behind-the-meter” generation). The associated CO₂ emissions are on the order of 600 Mt per year. While this is less than 2% of global emissions, it is clearly desirable to minimize – or completely eliminate – this type…

  • Prisprestanda för kraftslag i Sverige 2025

    Bengt J. OlssonLinkedIn: beosX/Twitter: @bengtxyz  Nedan följer en kort redovisning av capture prices (“fångstpriser”) för de huvudsakliga kraftslagen i utvalda elprisområden inom Sverige under 2025. Produktions och prisdata är tagna från ENTSO-E Transparency Platform, omräknat till timdata (efter att 15-minuters avräkning infördes under Oktober). Capture price för ett kraftslag beräknas som:Capture price=∑(DA_price×volume)∑volume\text{Capture price} = \frac{\sum (\text{DA\_price} \times \text{volume})}{\sum…

  • Balancing Europe’s Power System

    Bengt J. OlssonLinkedIn: beosX/Twitter: @bengtxyz  Looking at aggregated data from Energy-Charts can provide valuable system-level insights. In this analysis, focus is on the ALL Europe dataset, which aggregates electricity production and consumption across all European countries covered by Energy-Charts. This results in a very large and rich dataset. Since all included countries are electrically interconnected (unfortunately Great…

  • Effects of an Internal Constraint in Flow-Based Welfare Maximization

    Bengt J. OlssonLinkedIn: beosX/Twitter: @bengtxyz  The three-zone market model with flow-based constraints is a simple, yet non-trivial, framework for analysing how network constraints affect welfare maximization — and consequently prices, flows, and congestion income. It describes a market with three connected zones, where one zone also has an internal congestion. All zones have the same demand, but…

  • Buckminster Fuller and the Climate/Energy debate

    Bengt J. OlssonX: @bengtxyz LinkedIn: beos Fullerens and “buckyballs” As a PhD student in Orsay, just south of Paris, in the summer of 1986, I had the pleasure of meeting Professor Harry Kroto — who later became Sir Harry and a Nobel Laureate in Chemistry. His team had, more or less by serendipity, discovered the C₆₀ molecule: a…

  • BEKEN modellen – kort analys

    Bengt J. OlssonX: @bengtxyz LinkedIn: beos Inledning: Vad BEKEN försöker göra – och varför det är svårt Diskussionen om hur den svenska elmarknaden ska prissättas i relation till export är ständigt aktuell. Ett av de förslag som återkommit i debatten är den så kallade BEKEN-modellen, ibland även kallad ”Sverigepriser”. Grundidén är tilltalande: att skydda svenska elkunder från höga…

  • Alternative energy solutions for Ireland 2050

    🇮🇪 Bengt J. OlssonX: @bengtxyz LinkedIn: beos How can an island like Ireland reach net-zero by 2050? In the modelling here, two distinct pathways are presented – one fully renewable, and one with a significant nuclear share. Ireland is a particularly interesting case for energy system modelling. As an island, it requires a high degree of self-sufficiency in…

  • Europe’s energy system 2050, a simple sector-coupled model

    Bengt J. OlssonX: @bengtxyz LinkedIn: beos In this post, we examine a sector-coupled model of a future European energy system.The model includes three major energy carriers: electricity, hydrogen, and heat. It is based on hourly data (17,544 hours) from the All-Europe dataset of EnergyCharts for 2023–2024. The setup is a copper-plate model, meaning transmission constraints are ignored. This…
