Abstract

Electricity cost has become a central issue in managing global energy demand. Price based program through time of use tariff (TOU) program is one of the initiative to offer, as to provide sufficient benefit for both consumers and generations. Howerver, without any awareness in implementing the optimal load management strategy with new structure of tariff design will lead to the miss perception by electricity consumers. Therefore, this study offers an investigation toward an optimal load management strategy to reflect price signal for several types of TOU tariff design from several countries. The Ant Colony Optimization (ACO) algorithm is proposed to deal with load shifting strategy to determine the best load profiles. The main objective of the proposed method is to reduce the electricity cost while defining the best time segmentation that appropriate Malaysia residential load profiles. The sample load profiles data have been obtained from various type of residential house in Melaka such as single storey, double storey, semi-D, apartment and bungalow type of houses. The significant comparison between baseline flat tariff to several types of TOU tariff has shown improvement in percentage of electricity cost saving for approximately 7 to 40%. Futhermore, the identified controlled load as the weightage for the load management was observed where the maximum load shifting weightage was set up to 30% to reflect the ability of the consumers‟ effort. Thus, it is hoped that this study will lead to a better offer of the TOU tariff price initiative among residential consumers in the future action by electricity provider in Malaysia.
