Dynamic market-based transmission expansion planning considering fixed series compensation allocation

Abstract

This paper presents a market-based multi-period transmission expansion planning along with fixed series compensation (FSC) allocation. FSCs can dispatch power more efficiently over the transmission network as well as trading opportunities for market participants and thus improve market surplus and reduce the total transmission investment. The proposed planning may accordingly enhance network efficiency and improve social welfare for all participants. The proposed model is structured as a mixed integer linear programming problem. The CPLEX solver, as a commercial solver, is used to solve this MILP problem. Moreover, to find a reliable and viable optimal topology, N-1 security criterion is employed through the proposed model. This criterion is used to take into account any unanticipated operating condition due to unexpected transmission lines failures. The proposed model is applied to the Garver system as well-known system to show the effectiveness of FSC in dynamic transmission expansion planning (TEP).
