Feasibility study of district heating with CHP, thermal store and Heat Pump

摘要

Integration of Combined Heat and Power (CHP) plant, Heat Pump (HP), Thermal Storage (TS) and auxiliary boiler into a district heating scheme is able to provide an efficient way of using energy. This paper analyses the feasibility of such a scheme in Ebby Vale using the EnergyPro tool under existing energy market and policies. In the scenario based simulation, a 40279.7 MWh worth of heat was sent. The results show that the CHP+TS system present more encouraging environmental performance and acceptable profit margin, whilst the economic potential can be enhanced further with the addition of a HP unit. A sensitivity analysis was conducted to show to which extent economic assumptions will vary the result.
