Optimal power flow vs. economic dispatch

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 ...

Terrain Ruggedness Index for optimization problem

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 (...

Set a limit on value change of a binary variable

The abs function is piecewise linear, so you can represent it with two linear inequalities as shown in https://docs.mosek.com/modeling-cookbook/linear.html#absolute-...

Maximize charging, minimize cost

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 ...

Electricity market clearing price using fixed-MIP formulation?

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 ...

Why do we need SCED in addition to SCUC in RTO/ISO electricity markets?

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 ...

Why do we need SCED in addition to SCUC in RTO/ISO electricity markets?

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 ...

Optimal power flow vs. economic dispatch

[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 ...

Generation capacity adequacy assessment - intuition behind two state model

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 ...

Generation capacity adequacy assessment - intuition behind two state model

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 ...
