Impacts of Transmission Switching in Zonal Electricity Markets - Part II

Lété, Quentin [UCL] Papavasiliou, Anthony [UCL]

In this paper, we present a two-stage model of zonal electricity markets with day-ahead market clearing and real-time re-dispatch and balancing that accounts for transmission line switching at both stages. We show how the day-ahead problem with switching can be formulated as an adaptive robust optimization problem with mixed integer recourse and present a new algorithm for solving the adversarial max-min problem with interdiction game structure. We apply the model on a realistic instance of the Central Western European system and comment on the impacts of both proactive and reactive transmission switching on the operating costs of the system. Part 1 presents day-ahead models of a short-term zonal electricity market with switching, and describes our algorithmic approach for solving these models efficiently. Part 2 describes variants of the real-time model, and presents the results of our case study on the European market.
