THE EXTENSION OF AN ANALYTICAL METHOD FOR COMPARING NATURAL DIVERSITYTO DSM CONTROLLED DIVERSITY

The purpose of this paper is to report the extension of an analytical method of comparing natural diversity with controlled diversity, and t o show the results of comparing the peak load resulting from natural d iversity in a set of non-identical air conditioning units to the beak load of the same set of air conditioners under DSM control. The Centra l Limit Theorem for non-identical distributions is used as the theoret ical background for the extension. Several case studies are illustrate d and the results show that the peak load reduction by direct load con trol is almost linearly proportional to the increases of the on-time r atios of the air conditioners under control.
