Energy Management of a Smart Home Micro Grid in Presence of Micro-CCHP

Abstract

The micro grid studied in this paper supplies a residential building in a region with hot weather. The main distribution system source which is the focal point of this study is a micro-CCHP unit. Along with this source, photovoltaic Cells and the battery of a hybrid electric car are used respectively as the renewable energy and an electric energy storage source. In fact, by employing mathematical relations regarding micro-CCHP units this possibility is provided to study micro-CCHP units in a smart energy management system and observe their function in the presence of other distribution system sources. In addition to the heat load that provides the buildings required hot water, supplying the desired temperature of the building in hot seasons by adding an absorption chiller and adding cool load is studied and simulated. This kind of detailed modeling of heat and cool load intensifies the possibility of a better coordination between heat, cool and the output electric power of micro-CCHP which results in the optimal control and utilization of it.
