Optimal power dispatch of energy networks including external power exchanges

This paper presents a revision of a general framework which allows a standard modeling and optimization of arbitrary complex energy networks including multiple interconnected energy carriers, the so-called energy hubs, which are defined as interfaces among energy producers, consumers and the transportation infrastructure. In particular, the main contribution of this work arises from the explicit introduction in the modeling framework of external power exchanges from other surrounding networks and network peripheral hubs. Also, the impact of hydrogen storage in a network including electricity, natural gas and wind is studied by means of the proposed general network formulation, showing its high flexibility in terms of modeling detail and accuracy.
