Central power systems predominantly consist of large generators that provide electricity to a broad consumer base through extensive networks. This conventional top-down supply is, however, being challenged by peak demand, energy losses, ageing infrastructure and climate change. Localised distributed energy systems (DES), consisting of clusters of small-scale technologies and various energy services and interactions at the consumer level, are increasingly presented as solutions to these challenges. However, for DES to become viable, a novel cross-disciplinary design approach is still required that encompasses multiple stakeholder interests. This thesis aims to address this need through developing a flexible multi-objective decision-making framework for DES design, from an engineering and regulatory perspective, using mathematical programming techniques. A superstructure mixed-integer linear programming approach is hereto developed to optimise residential energy system designs framed by location-specific parameters and required electricity, heating and cooling demands. Engineering design is optimised in terms of selection, siting and sizing of energy supply alternatives and interactions from a considered pool of options. Multiple stakeholder-driven minimisation objectives are included through Pareto trade-offs, ensuring a system design that is not only competitive (total annualised energy cost) but also introduces security of supply (electrical system unavailability) and environmental benefits (annual CO2 emissions) to the neighbourhood as compared with conventional configurations. DES, furthermore, require an adequate regulatory framework to fit in with conventional systems. Nevertheless, regulation is still lagging behind their technological development. The developed design approach is therefore extended to enable analysis of DES regulatory framework aspects by identifying quantifiable relations, such as type, scale and ownership, between engineering design, organisation and regulation. The framework is applied to a small South Australian neighbourhood to illustrate its capability for DES design analyses and decision-making within conventional power systems generally. The developed approach ensures DES applicability within conventional power systems and their relevance to governing energy regulation.
