The basic power flow (PF) problem calculates how much power should be sent around a transmission or distribution network in one time period (at one snapshot in time). It ignores how that power is produced. Economic dispatch calculates how much power is produced at each power generator, ignoring the transmission network. Economic dispatch is a very simple ...

Yes. The ruggedness of a landscape is a measure of how much variability is observed between neighbouring solutions, and it can be computed using the landscape correlation function. Rugged landscapes (with a very low correlation) typically have lots of local minima and are more difficult to traverse than smooth landscapes (correlation close to 1). For a fixed ...

I would encourage you to think about the model and the algorithm separately. I think your question is really about what sort of model you should build. Once you know that, the question of algorithm is largely determined, because you'll probably just be passing your model to a solver that will handle the algorithmic part automatically. My short answer is ...

I've gained sufficient information in last couple of weeks to write an answer myself. As a prerequisite to the discussion, please note the difference between uniform vs non-uniform market clearing price. Non-convexities present in electricity market clearing models would lead to non-uniform prices, which would result in participants loosing money if no ...

With my best understanding (mostly from the practice of MISO), the goal of Day-ahead SCUC is to provide commitment decisions for the next day while the commitment decisions will also guarantee there are enough "average" power/energy with sufficient ramping for each of the considered discretized time-window. (See [1] for the manual reference) In ...

This is because SCUC provided on/off + dispatch Sometimes when you are at time t the demand is not the same as the predicted value and you need to adjust the P values (not on/off since they can't be changed) then you will run a SCED to make sure everything is fine

[taylor2015convex] provides a holistic view on economic dispatch, unit commitment, and optimal power flow. The continuous operation of power systems requires multi-period optimal power flow, which is discussed in chapter 4. The decision concerning long-term investments is the most complicated programming problems in power systems, which is discussed in ...

In reliability studies, the availability of conventional plants is modelled with two states, available and unavailable. A plant can be unavailable due to scheduled maintenance or due to an outage. In order to model the outages, you need some information for the mean time to failure and the mean time to repair, which can be used to model the transition ...

The classic Reliability assessment assumes that a device either works or not. Additionally, you can assume some derated states. For example, consider a Power plant with $P_{max} = 100MW$. You can model it as $0$ or $100$. You can model it as $0$, $50$ or $100$. Usually, it is for conventional power plants.
