Abstract

Abstract:
Due to the rapid growth of the population in Kuching area lately, the power
consumption pattern, diversity factor, after diversity maximum demand (ADMD) and
load factor become the critical issues to be studied and revised in details in order to
improve the system planning and reduce the capital expenditure. To achieve this
objective, method to determine the power consumption pattern for different class of
consumers in Kuching area is proposed in this paper. The power consumption data for
consumers were recorded using a specialized meters installed at their premises. The
sampling theory is present in this paper to determine the sample size and the number of
meters needed to be installed. The raw data obtained from these meters were analyzed to
obtain the pattern of power consumption for different classes of consumers in Kuching
to determine the load factor and diversity factor. Besides, the value of ADMD was
calculated to verify the optimal amount of load to be supplied to the housing
development area, resulting in better planning and leading to a more efficient usage of
resources to generate electricity.
