IEEE-30 energy system data of multi-period market with intertemporal constraints

This is the dataset that is used for the original article: "Locational marginal pricing in multi-period AC OPF environment"

The dataset consists of the following files

Case1.zip

Case2.zip

Case3.zip

case_modifications.py

data_spec.py

OPF_formulation.pdf

Multiperiod AC OPF is given in OPF_formulation.pdf. Modifications of traditional IEEE 30-node case are given in case_modifications.py

The case files incorporate input and output multiperiod AC OPF and LMP decomposition data in csv and pickle formats. Data structure of case files is given in data_spec.py.

For python users pickle files are given. Nevertheless, python environment is not required. Specification can be read as a text file. All necessary data are repeated in csv format.

Step 1 are to define LMPs of  limited energy resources or storage resources that are formed by actual marginal resources from all time periods (first LMP definition in fig. 6 in the paper).

Step 2 are to define all other LMPs at price-taking nodes (second LMP definition in fig. 6 in the paper).

The following interrelation between Lagrange multipliers, LMP components, and price-bonding factors holds true:
