Abstract

A key enabler for the smart grid is the fine-grained monitoring of power utilization. Although such a mechanism is helpful in the optimization of the whole electricity generation, distribution, and consumption cycle, it also creates opportunities for the potential adversaries in deducing the activities and habits of the subscribers. In fact, by utilizing the standard and readily available tools of nonintrusive load monitoring (NILM) techniques on the metered electricity data, many details of customers’ personal lives can be easily discovered. Therefore, the prevention of such adversarial exploitation is of utmost importance for privacy protection. One strong privacy preservation approach is the modification of the metered data through the use of on-site storage units in conjunction with renewable energy resources. In this talk, we introduce a novel mathematical programming framework to model privacy-enhanced power scheduling strategies inspired and elicited from the literature. We employ all the relevant techniques for the modification of the actual electricity utilization (i.e., on-site battery, renewable energy resources, and appliance load moderation). In addition to privacy concerns, we consider the monetary cost and disutility of the users in our objective functions. Later, we also include utility companies' objectives of minimizing the peak-to-average ratio and minimizing the variation of the load demand. We present a comprehensive exploration of the relationships between the objectives of consumers and utility companies and their effects on one another. Lastly, we discuss the role of measured reactive power in NILM and how reactive power can be shaped in order to ensure privacy.
