A Feasibility Study for a Wind/Diesel Hybrid System withDesalination for Star Island, NH

摘要

This work investigates the potential installation of a wind-diesel hybrid system for Star Island, NewrnHampshire that also includes a desalination system component. In addition to supplying electricity during the peakrndemand summer months, this system attempted to balance the seasonal mismatch between wind resource andrndemand load via the production of potable water during the winter months. A proposed system configurationrnfeaturing wind-diesel components as well as a desalination system was analytically modeled using HOMER andrnHybrid2 computational codes. Using specific data obtained from this site, these models calculated the electricalrngeneration as well as the excess energy produced by the wind turbines that would be available to power arndesalination plant. The desalination plant was chosen to be a variable power mechanical vapor compression unit,rnwhose performance was simulated using data from an existing similar sized unit. Energy produced, fuel savings,rnand water processed (and stored) were determined for a number of commercially available wind turbines. Therneconomics of the proposed system were not determined to be favorable at the present time. However, the proposedrnsystem was determined to be technically feasible and it offers some interesting system design and environmental advantages.
