A microgrid model for the integrated operation of heat and electricity

This paper presents a model to operate the microgrid combined heat and electricity in DongShin University (DSU) campus, Korea. Since a relatively large amount of heat energy has been consumed in DSU, MG system is designed containing not only general energyproducing facilities but also the thermal storage tank. The usefulness of the facility that produces both heat and electricity would be raised through the function of the balancing operation in the proposed EMS. The operating modes of EMS have been diversified to enhance operational accuracy and to respond to specific situations. The proposed EMS is based on the operational purpose of saving electric energy's demand charge and reducing electricity and thermal energy usage rate. It is expected that the proposed MG model would contribute greatly to activation of various similar sites.
