Abstract :
Recently it has been strongly required to reduce energy consumption to cope with global warming. Since energy consumption in commercial and residential sectors are increasing while the industrial sector is almost constant in Japan, policies to lead to energy conservation in urban areas are quite important. This study aims at investigating the performance of urban energy systems which install combined heat and power (CHP) as a direct heating and cooling (DHC) plant and the influence of CHP on the structure of electric power systems of electric utilities. The behavior of energy technologies and the possibility of energy conservation are evaluated based on an optimization model with respect to total system cost. Sensitivity analysis of population allocation into urban areas indicates that fossil fuel consumption varies in the range of 10%-20% compared with conventional systems
