ABSTRACT
Smart grid, managed by intelligent devices, have demonstrated great potentials to help residential customers to optimally schedule and manage the appliances' energy consumption. Due to the fine-grained power consumption information collected by smart meter, the customers' privacy becomes a serious concern. Combined with the effects of fake guideline electricity price, this paper focuses an on-line appliance scheduling design to protect customers' privacy in a cost-effective way, while taking into account the influences of non-schedulable appliances' operation uncertainties. We formulate the problem by minimizing the expected sum of electricity cost and achieving acceptable privacy protection. Without knowledge of future electricity consumptions, an on-line scheduling algorithm is proposed based on the only current observations by using a stochastic dynamic programming technique. The simulation results demonstrate the effectiveness of the proposed algorithm using real-world data.
