Summary:
AMR (Automatic Meter Reading) system is expected to be used for real time load monitoring to optimize power generation and energy efficiency. Recently, Batra et al. propose a technique to estimate consumer's lifestyle from a real-time load profile. In order to overcome this issue, BLH (Battery-based Load Hiding) algorithms are proposed to obfuscate an actual load profile by charging and discharging. Although such BLH algorithms have already been studied, it is important to consider multiple households case where one battery is shared among them because a battery is very expensive. In this paper, we propose a new BLH algorithm for two households as an example to consider monetary fairness. In our scheme, the core unit calculates the difference between the charged amount and discharged one. If the difference is bigger than the pre-defined threshold (monetary unfair occurs), the disadvantageous household is given priority to discharge the battery and the other household should charge to achieve monetary fairness. The efficiency of our scheme is demonstrated through the computer simulation with a real dataset.
