Affine Policies for Flexibility Provision by Natural Gas Networks to Power Systems

Online appendix for the paper - "Affine Policies for Flexibility Provision by Natural Gas Networks to Power Systems", containing the power generators, gas producers and demand data as well as physical characteristics of the electrical transmission lines and gas pipelines. The empirically estimated forecast error covariance matrix used in the model is provided as well. The power systems and natural gas systems data is adapted from: C. Ordoudis, P. Pinson and J. M. González, "An integrated market for electricity and natural gas systems with stochastic power producers", European Journal of Operational Research, vol. 272, no. 2, pp. 642-654, 2019.
