Niu, Yukun, Tan, Xiaobin, Zhou, Zifei, Zheng, Jiangyu, Zhu, Jin.  2013.  Privacy Protection Scheme in Smart Grid Using Rechargeable Battery. Proceedings of the 32nd Chinese Control Conference. :8825–8830.

It can get the user's privacy and home energy use information by analyzing the user's electrical load information in smart grid, and this is an area of concern. A rechargeable battery may be used in the home network to protect user's privacy. In this paper, the battery can neither charge nor discharge, and the power of battery is adjustable, at the same time, we model the real user's electrical load information and the battery power information and the recorded electrical power of smart meters which are processed with discrete way. Then we put forward a heuristic algorithm which can make the rate of information leakage less than existing solutions. We use statistical methods to protect user's privacy, the theoretical analysis and the examples show that our solution makes the scene design more reasonable and is more effective than existing solutions to avoid the leakage of the privacy.
