Study on operation of area energy system that interchanges energy among multiple heat source plants

Satoru Amemiya, Masaya Okumiya

Abstract: Distributed energy systems are henceforth expected to function as area energy network models. However, the optimization of such a system is rather complex. Thus, it is very important to study effective heat source operation in the planning phase. The purpose of the present study is to optimize the operation of a distributed heat source system that interchanges energy among buildings or plants. In the present paper, a novel simulation model is developed for optimizing the operation of this system, and a case study is conducted using this model. In the case study, a restriction on spaces for constructing large-scale heat source plants, such as those in central urban areas, is implemented. Heat sources are distributed among a number of plants and connect heating and cooling equipment among these plants. The simulation results show that the distributed heat source system conserves more energy or as much energy as a conventional large-scale district heating and cooling system, owing to optimized operation. Furthermore, optimum operation differs with the composition of the heat exchanging network and the amount of heat required.
