This is a NAVAL POSTGRADUATE SCHOOL MONTEREY CA report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A092604. The abstract provided by the Pentagon follows: Analysis and simulations were performed to provide recommendations on how to improve the cost- effectiveness of the operation of remote hybrid power systems supporting various Alaskan National Distress System (NDS) communications sites. The study characterizes the loads and power sources at two NDS sites. Basic lead-acid battery theory is applied to produce a mathematical model to simulate the normal operation of the hybrid power system. 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 hybrid controller settings.
