  In this paper, we present a comprehensive survey of privacy-preserving
schemes for Smart Grid communications. Specifically, we select and in-detail
examine thirty privacy preserving schemes developed for or applied in the
context of Smart Grids. Based on the communication and system models, we
classify these schemes that are published between 2013 and 2016, in five
categories, including, 1) Smart grid with the advanced metering infrastructure,
2) Data aggregation communications, 3) Smart grid marketing architecture, 4)
Smart community of home gateways, and 5) Vehicle-to grid architecture. For each
scheme, we survey the attacks of leaking privacy, countermeasures, and game
theoretic approaches. In addition, we review the survey articles published in
the recent years that deal with Smart Grids communications, applications,
standardization, and security. Based on the current survey, several
recommendations for further research are discussed at the end of this paper.
