A team at the Networks Research Laboratory, University of Cyprus, which Web-enabled the plogg using RESTful architecture, conducted feasibility studies using variable pricing structures to determine the effects of simulated Demand Response programs when activating connected appliances in low-rate hours. The team concluded that applying an optimizing policy for all electrical appliances in the home can achieve a 10.85 percent reduction in the bill of a typical average home. That works out to monthly savings of EUR 6 in a 10 percent tariff reduction and EUR 19 in a 30 percent reduction.
Similarly, the MiDDaS dynamic demand and battery storage project has prioritized scheduled load events, including Electric Vehicle (EV) charging, when rates are low and exporting electricity from battery storage when the rates are high.
The plogg is used to create a wireless smart metering network inside the house to implement dynamic demand for EV charging and grid-tie export. The plogg network controller is the gateway that communicates with a utility supplier’s central server, sending minute interval data and receiving variable price tariffs.
Andreas Kamilaris of the University of Cyprus explains, “Advanced home automation, high flexibility and energy conservation can be achieved when using the Web as a platform. A future cloud-based smart grid strategy would allow the seamless integration of the grid with Web-based, energy-aware smart homes.”
