Integration of Multiple In-House Heat Stations into One Energy Flexible Heat System

Abstract

This study is focused towards assessing the potential for energy savings and cost reduction by integrating multiple in-house heat stations in several buildings into one larger energy flexible heat system. All existing boilers in stand-alone systems are kept as production units of a new merged system, and will be in addressed and operated when the condition demands it. In this study, energy and cost calculations are done on an hourly basis. Which combinations of boilers to be used in each time step are determined from the lowest running cost for each time step. The results of the case study show a clear savings potential for both energy and costs.
