Pyomo optimisation not working (gas plant dispatch)
background I am trying to write an pyomo script to optimally dispatch a gas plant based on perfect foresight of electricity prices. I believe I am 90% of the way there, just a few issues. Problem The ...
Terrain Ruggedness Index for optimization problem
If I want to study the smoothness of the energy landscape of a cost function, is there any metric similar to Terrain Ruggedness Index used in geology?
Generation capacity adequacy assessment - intuition behind two state model
While doing some reading on the power system resource adequacy studies I have noticed that the standard (baseline?) model for generation availability is the two state model - assumes two possible ...
Electricity market clearing price using fixed-MIP formulation?
Dual information of electricity markets clearing problem is required to calculate the marginal clearing price. As most electricity market problems are based on MIP (and dual information of MIP is not ...
Why do we need SCED in addition to SCUC in RTO/ISO electricity markets?
I understand that we use SCUC (Security Constrained Unit Commitment) and SCED (Security Constrained Economic Dispatch) in day ahead electricity market – According to the literature, SCUC is used to ...
Any good resource for solving power system optimization in GAMS?
I am looking for some resources to learn the modelling tricks of GAMS in power system optimisation problems.
Maximize charging, minimize cost
The task pertains to choosing an algorithm based on the data, requirements and constraints. I have a number of electrical devices ($d_1,d_2,\dots,d_n$) with batteries. Throughout the day I will ...
Optimal power flow vs. economic dispatch
What is the difference between the two common optimization models for electricity systems, optimal power flow (OPF) and economic dispatch (ED)? I've heard people say that ED is just a multi-period ...
