Analysis of Load Profiles and Recommendation for a mix of Sustainable Energy Technologies of a Residential-Commercial Estate

H. A. Dandajeh

Abstract


This paper presents analysis of energy demand of a residential-commercial estate in both summer and winter seasons for a daily hourly interval of 24. Expected maximum electrical and thermal energy demand of the estate were assessed and found to be 3MW and 2.5MW respectively. These energy demands were subsequently matched, using EnergyPlus-V7.1.0 Software, with three proposed energy generating technologies which are recommended to power the estate. The energy technologies suggested were two combined heat and power (CHPs) of capacities 2 and 2.5MW and a 10MW stand-alone wind turbine with a capacity factor of 20%. A one (1 MW) back-up hydro pump energy storage was also recommended to be installed to store the excess energy generated. The excess energy was projected to be used during the peak daily demand periods and can also be sold to the neighboring estates. Recommendation for the CHP was based on the thermal energy to power ratios ranging from 0.2 to 0.6 in the summer and winter, respectively.
