Sažetak
The heat pumps are recognized as energy efficient and environmentally friendly technologies for cooling and heating. Because of the ability to convert electrical energy to heating and cooling energy, which can then be stored in thermal tanks, their greatest potential can be found in pairing them with smart grid systems. By pairing, heat pumps can contribute in making the power grid more dynamic, reduce the integration problems which could arise from high shares of renewables, and rise the shares of mostly decentralized renewable energy sources in traditionally centralized energy systems. The objective of this paper is to identify the technical and economic potential of heat pumps with storage tanks in hotels located on the Mediterranean coast. Energy demand was studied for a complete year on an hourly basis and the cost-benefit analysis was made for installing the heat pump, as well as the critical excess regulation for which the electricity costs on energy demand market were used. The possibility to utilize heat pumps with storage tanks in critical excess regulation strategy and the overall effect of their usage on power grid were analysed. Days with the highest and lowest demands in both heating and cooling season were taken as representative days, with which the possibilities to regulate critical excess were presented. Results show that, although heat pump is a cost-effective technology for the regarded hotel, without using storage tanks, it would work during the peak electricity costs.
