Analysis and cost optimization of a USCG remote hybrid power system

Abstract

Analysis and simulations were performed to provide recommendations on how toimprove the cost-effectiveness of the operation of remote hybrid power systems supportingvarious Alaskan National Distress System (NDS) communications sites. The studycharacterizes the loads and power sources at two NDS sites. Basic lead-acid battery theory isapplied to produce a mathematical model to simulate the normal operation of the hybrid powersystem. Data from 2001 is analyzed to account for the effect of solar energy on the model.Results from the simulations indicate that a cost savings is realizable through improved hybridcontroller settings.
