Power System modelling

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…

Bengt J. OlssonTwitter: @bengtxyz LinkedIn: beos IntroductionModelResultsDiscussion and ConclusionsUpdate 1: Hydrogen store instead of Battery storeUpdate 2: Nuclear power instead of Biopower Introduction The South West Interconnected System (SWIS) power system in Western Australia (WA) is quite interesting for a couple of reasons Here is a balance model for a optimized SWIS power system consisting of Wind, Solar…

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…

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……

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…

Bengt J. OlssonTwitter: @bengtxyz LinkedIn: beos SWETH systemSWENTH systemDiscussionConclusionsUpdate 2023-07-08 Modeling a fossil free German power system Inspired by the RethinkX SWB (Solar, Wind and Batteries) model (see this blog post), a more realistic model for Germany, with 500 TWh of consumption, is presented here. The model is based on either of these two alternatives SWETH Solar, Wind,…

Bengt J. OlssonTwitter: @bengtxyz LinkedIn: beos RethinkX has presented a proposal for replacing Germany’s power system with an all renewable power system consisting of wind and solar power only, and with batteries as back-up/balancing source (a “SWB” system). It would also be a completely self-sufficient power system, with no import dependence. From a modelling point of view this…

Bengt J. OlssonTwitter: @bengtxyz LinkedIn: beos This blog is a translation of an article I wrote for the Swedish on-line magazine Second Opinion. In this article, Bengt J. Olsson evaluates different methods for generating the green electricity needed for hydrogen production. His conclusion is that electricity from a balanced national electricity system provides the best and most even…
