Privacy protection scheme in smart grid using rechargeable battery

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.
