Web-based simulation tools for the allocation of cross-border transmission rights and implementation aspects in South-East Europe

In South-East Europe (SEE), system operators (SO) started with the gradual implementation of market-based methods for the transmission capacity allocation. In this paper, the special web-based simulating software, developed for the daily explicit auction and allocation of tie-lines transmission rights on the borders of TSO-EPCG (Transmission System Operator of Montenegro), is presented as well as the monthly results achieved with its implementation. Details on the aforementioned simulator are given. After that, a small, coordinated flow-based internet simulator is created for the testing purposes, using PHP/MySQL and MATLAB as the development tools. The main advantages of the coordinated flow-based auction over the explicit NTC-based method are clearly underlined. Therefore, the proposed method can be a successful substitution for the currently applied market-based methods, and a step towards the open electricity market in SEE.
