Abstract
This paper discusses the use of coordinated wide area demand side management (DSM) for facilitating cross-border power transfers between the interconnected transmission networks. It proposes a methodology for ranking transmission network loads eligible for DSM programs based on the network topology and the size of DSM assets. The influence of network topology is accounted for by considering distribution factors (DFs), and the size of DSM assets by considering the available demand flexibility (upward or downward variation) of load buses. The industrial end-users connected directly to transmission network and the bulk supply points of distribution networks are considered the two main types of DSM providers at the transmission level. The proposed approach facilitates analytical evaluation of the effects of DSM on power transfers and such makes a valuable decision-support tool for any transmission system operator, whether it is used for network operation or planning. The methodology is illustrated on a simplified model of four interconnected European transmission networks and thus provides a realistic assessment of the extent to which cross-border DSM can be used to regulate power transfers between countries.
