We're about to acquire a significant new cyber- vulnerability. The world's energy utilities are starting to install hundreds of millions of 'smart meters' which contain a remote off switch. Its main purpose is to ensure that customers who default on their payments can be switched remotely to a prepay tariff; secondary purposes include supporting interruptible tariffs and implementing rolling power...
Smart meters, introduced by smart grid technologies, enable power distribution companies to price electricity differently for different times of the day. Such dynamic pricing schemes help the power companies to modulate the aggregate demand of electricity based on the supply. Accordingly, cloud providers, which are often the largest consumers of electricity, should be able to respond to various dynamic...
PRIME (PoweRline Intelligent Metering Evolution) is one of the prominent upcoming powerline communication technologies, targeted for use in smart metering applications. The PRIME PHY / MAC specifications are open, publicly available and are developed by the PRIME Alliance, an industry consortium that includes utilities, meter vendors and semiconductor suppliers. PRIME employs OFDM modulation in the...
The evolution of traditional electricity grid into a state-of-the-art Smart Grid will need innovation in a number of dimensions: seamless integration of renewable energy sources, management of intermittent power supplies, realtime demand response, energy pricing strategy etc. The grid configuration will change from the central broadcasting network into a more distributed and dynamic network with two-way...
In this paper, we propose a framework for coupling the communication network of a smart grid with the power distribution network in an effort to better utilize the scarce energy resources. We believe that an agile, robust and effective communication infrastructure, relying on a service-oriented network paradigm is essential for proper operation of a greener and smarter electricity grid. The communication...
The security and privacy of future smart grid and smart metering networks is important to their rollout and eventual acceptance by the public: research in this area is ongoing and smart meter users will need to be reassured that their data is secure. This paper describes a method for securely anonymizing frequent (for example, every few minutes) electrical metering data sent by a smart meter. Although...
A number of governments and organizations around the world agree that the first step to address national and international problems such as energy independence, global warming or emergency resilience, is the redesign of electricity networks, known as Smart Grids. Typically, power grids have "broadcasted" power from generation plants to large population of consumers on a suboptimal way. Nevertheless,...
In this paper, we present a distributed incremental data aggregation approach, in which data aggregation is performed at all smart meters involved in routing the data from the source meter to the collector unit. With a carefully constructed aggregation tree, the aggregation route covers the entire local neighborhood or any arbitrary set of designated nodes with minimum overhead. To protect user privacy,...
Whilst security is generally perceived as an important constituent of communication systems, this paper offers a viable security-communication-tradeoff particularly tailored to Advanced Metering Infrastructures (AMIs) in Smart Grid systems. These systems, often composed of embedded nodes with highly constrained resources, require e.g. metering data to be delivered efficiently whilst neither jeopardizing...
Redundant metering is frequently used to verify the integrity of billing data reported by advanced metering infrastructure, but the redundant measurement introduces a potential confidentiality leak. We propose a way to encode the redundant measurement at a bit rate below its entropy, so that it cannot be decoded from the encoded bits alone. In this way, we guarantee information-theoretic confidentiality,...
