Effect of Delays in the Connection-to-the-Grid Time of New Generation Power Plants over Transmission Planning

Abstract

The start-up times of new power plants are subject to significant uncertainty and they have an important impact on the planning of the transmission network. We propose a model for the electricity network planning inspired in the Robust Optimization approach, which incorporates the uncertainty related with the time in which the new power plants will be connected. Using the proposed model, we measure the impact of these delays over the system cost and the optimal network plan, with a special focus on the effect of the delays in building some renewable power plants.
