Security analysis of proactive participation of smart buildings in smart grid

Demand response (DR) is an effective mechanism in improving power system efficiency and reducing energy cost for customers. However, DR processes might be vulnerable to cyber attacks from the usage of advanced metering infrastructure and wide-area network to exchange information. In this paper, we study potential attacks for a proactive demand participation scheme we recently proposed and for a conventional passive demand response scheme, particularly focusing on guideline price manipulation attacks. Our experiment results demonstrate that 1) guideline price manipulations may significantly lower the attacker´s own electricity consumption cost while increasing other customers´ cost, for both proactive and passive schemes; 2) such impact is less severe in the proactive scheme, i.e., the proactive demand participation scheme is more robust with respect to guideline price manipulation than the conventional DR.
