Abstract:

This paper describes an approach to model interconnected national energy systems using the concept of energy hubs. Each country is modeled as an energy hub, characterized by the national generation infrastructures for heat and electricity, the demand for heat and electricity as well as properties detailing mobility demand. Countries are interconnected via electricity and gas networks, i.e. it is possible to import or export electricity and/or gas. The paper gives a short introduction to the concept of energy hubs and describes the extensions of the concept to account for national multi-carrier energy systems. In a subsequent part the network model is introduced. The different constituents (generation, demand, transmission infrastructures) form an optimization problem, where a numerical solution approach is combined with particle swarm optimization. Furthermore, it is described how the relevant data concerning demand, generation and network infrastructures was obtained. The paper is concluded with three case studies demonstrating the applicability of the proposed approach.

I. Introduction

One major goal of European energy policy is the establishment of a pan-European market. In regulation 1228/2003 of the European parliament and the council [1] it is stated that: “The creation of a real internal electricity market should be promoted through an intensification of trade in electricity, which is currently underdeveloped compared with other sectors of the economy.” Such a reinforcement of trade is not only an objective in the electricity sector. Similar reasoning exists for natural gas markets and related infrastructures. Hence, the priority projects for Trans-European Energy Networks (TEN-E) include both: recommendations in terms of investments in cross-border electricity and natural gas interconnections. Legislation regarding markets as well the stimulation of investment projects may be seen as two major measures to further intensify trade. However, the success of these strategies seems to be closely linked to the overall developments in terms of technological progress in energy generation and transmission, depletion of fossil resources and related price changes for primary energy carriers, national policies in terms of renewable integration, energy efficiency, etc.
