abstract
A promising and shortly emerging energy supply chain network based on small-scale microgeneration through micro combined heat and power systems is proposed, modeled and optimized in this work. Interchange of electrical energy can take place among the members of this regional microgrid, which is connected to the main electrical grid for potential power interchange with it. A mathematical programming framework is developed for the operational planning of such energy supply chain networks. The minimization of operating and trade costs under full energy demand satisfaction constitutes the optimization goal of this study. Additionally, an alternative microgrid structure that allows the heat interchange within subgroups of the overall microgrid is proposed, and the initial mathematical model is extended to deal with this new aspect. An illustrative example is presented in order to highlight the particular significance of selecting a proper optimization goal that thoroughly takes into account the major operational, technical and economic driven factors of the problem in question. Also, a number of real-world size case studies are used to illustrate the efficiency and the potential benefits of the suggested microgeneration energy supply chain networks. Finally, some concluding remarks are drawn and future research directions towards the treatment of uncertainty and the on-line management of such energy systems are identified. 2013 AACC American Automatic Control Council.
