Integrating Energy Storage Systems and Transmission Expansion Planning in Renewable Energy Sources Power Systems

Abstract

Energy storage systems (ESS) are more and more used in power systems where renewable energy sources (RES) are integrated. ESS can participate in frequency control and also represents a flexible solution to supply the demands in power systems. The mathematical model presented in this paper minimizes the investment costs, load shedding costs and generation costs, concomitant with integrating ESS and building new transmission lines if the capacity of the existing ones is not sufficient.
