We are developing a next-generation power grid in the low-carbon era, which operates and controls demand-side equipment as well as that on the power generation and transmission sides. For these operations and controls, a computer unit, called a customer gateway in this paper, exchanges data with devices in customer premises and those in this grid. To ensure interoperability for communications with...
Smart Grid collectively refers to various visions of how energy generation, distribution, and consumption should be managed to overcome many of the shortcomings of today's electricity grids and to sustain our ever more electricity dependent societies. One important enabling component of Smart Grid will be a fine-grained and reliable communications infrastructure that links together the many elements...
The emergence of cloud computing has established a trend towards building massive, energy-hungry, and geographically distributed data centers. Due to their enormous energy consumption, data centers are expected to have major impact on the electric grid by significantly increasing the load at locations where they are built. However, data centers and cloud computing also provide opportunities to help...
In this paper, we study Demand Response (DR) problematics for different levels of information sharing in a smart grid. We propose a dynamic pricing scheme incentivizing consumers to achieve an aggregate load profile suitable for utilities, and study how close they can get to an ideal flat profile depending on how much information they share. When customers can share all their load profiles, we provide...
In this paper, we consider a smart power infrastructure, where several subscribers share a common energy source. Each subscriber is equipped with an energy consumption controller (ECC) unit as part of its smart meter. Each smart meter is connected to not only the power grid but also a communication infrastructure such as a local area network. This allows two-way communication among smart meters. Considering...
Dynamic energy pricing is a promising development that addresses the concern of finding an environmentally friendly solution to meeting energy needs of customers while minimizing their electrical energy bill. In this paper, we mathematically formulate the electrical energy bill minimization problem for cooperative networked consumers who have a single energy bill, such as those working in a commercial/industrial...
Future Power Grids are imagined to turn into an "Internet of Energies" with intelligent distributed control of a vast amount of controllable consuming and producing devices. This asks for advanced information systems to support the evolution to extended demand-response grid operations impacted by interactive communication control between different stakeholders and demands for high power...
Using smart grids to build low carbon networks is one of the most challenging topics in ICT (Information and Communication Technologies) industry. One of the first worldwide initiatives is the GreenStar Network, completely powered by renewable energy sources such as solar, wind and hydroelectricity across Canada. Smart grid techniques are deployed to migrate data centers among network nodes according...
Faced with an uncertain path forward to renewables portfolio standard (RPS) goals and the high cost of energy storage, we believe that deep demand side management must be a central strategy to achieve widespread penetration of renewable energy sources. We examine the variability of wind as a source of renewable, non-dispatchable energy and the loads that can be dispatched to match sources of this...
