Demand side management (DSM) is one of the popular strategies to enhance the suitability of the electrical grids, given the fact that the load on the system is ever increasing exponentially. Demand response is a DSM mechanism in which the voluntary participation of the consumers in energy management is rewarded using the momentary or long-term incentives. This paper proposes DR strategies for passive residential household loads in Singapore and prepare for the upcoming liberalisation of the open electricity market in Singapore. In addition, this paper presents the viability of the developed DR strategies in terms of comfort indices such as consumption indices, monetary indices as well as dissatisfaction indices. The performance of the proposed DR strategies is verified using a practical case study data. The simulation results show the effect of the proposed strategies on the load consumption and their role in encouraging the consumers to participate in DR.
