Integrated generation- transmission expansion planning: a review of the state of the art

Abstract

In the last decade a great number of research works have approached the power systems planning problem by coordinating in a single optimization problem the generation expansion planning (GEP) and the transmission expansion planning (TEP). GEP is usually carried out disregarding network constraints and under an energetic perspective. On the other hand, TEP aims to find network reinforcements that meet the expected demand in an economical and reliable way. The integration of these problems has been approached using different methods, models, and objective functions. This paper presents an exhaustive review of the integrated GEP-TEP problem from different points of view such as modeling, solving methods, reliability considerations, among others. There are review papers in the specialized literature that characterize the GEP and TEP problem independently. However, there are no reviews regarding the integrated GEP-TEP problem. So, it is needed to characterize aspects of the power systems integrated planning problem with the aim to provide consulting tools for researchers in this field.
