Abstract
Proposed future UK energy supply infrastructures harbor ambitions for achieving a sustainable and reliable energy network, which can potentially be realized through a decentralized and flexible approach to electricity generation. Such an energy system will be expected to deliver these objectives through the widespread use of distributed energy resources, thereby contributing to the international aim of a low carbon future. Existing research in the area of distributed energy resource integration has developed the energy hub methodology to formally model flows within an energy network, abstracting generation from multiple energy carriers (e.g., electricity, wind and natural gas) and allowing a modular energy network construction that facilitates optimal placement of distributed energy resources within each hub. This article will present the energy hub approach to modeling a decentralized energy network, illustrated with two case studies from the East and West coasts of Scotland. The resulting analysis will show the impact of two scenarios with different energy mixes available whilst reflecting the subtle differences in demands across areas with different weather profiles. This is a fundamental progression of existing distributed energy resource research to date in that individual characteristics and costs of a mixture of technologies are modeled. Such analysis will be pivotal in planning future networks to ensure that they function optimally and also in directing policy to encourage consumers to adopt a different approach to energy generation.
