A review on generation and transmission expansion co-planning models under a market environment

I.C. González-Romero, S. Wogrin, T. Gómez

This paper presents a review of the state of the art on the coordination of generation and transmission expansion planning. First, we present the different modelling approaches to represent transmission and generation operation and investment in generation and transmission expansion models, with an emphasis on the co-optimisation problem. Second, a comprehensive review on co-planning equilibrium models in a market environment is carried out. We consider that centralized (in some cases decentralized) transmission companies take network expansion decisions while decentralized generation companies decide their capacity expansion. Compared with previous works, we carry out a detailed classification of equilibrium models. We explicitly differentiate their hierarchical and regulatory structure with their equivalent reduced structure (after the application of level reduction methodologies to solve the equilibria). Additionally, we classify the distinctive market approaches that usually represent the lower level of co-planning problems. Finally, we examine the existing investment and operation modelling options and we identify gaps in the literature of each one of the mentioned categories.
