Distribution automation: Applications to move from today's distribution system to tomorrow's smartgrid
In 2008 the Hydro-Québec Distribution roadmap was completed. The resulting roadmap is based on customers' expectations, Hydro-Québec's business drivers, available technologies, Hydro-Québec's context and electrical distribution industry trends. This paper will present the distribution roadmap and then will focus on application and technology strategy to move from today's distribution network to tomorrow's Smartgrid.
Planning and operating experience of the Hydro-Québec smart zone and its role in supporting the evolution of the distribution system
SUMMARY This paper describes the Hydro-Quebec Distribution Smart Zone and its role in the evolution of the distribution system at Hydro-Quebec. Results from f ield data are presented and integration experience related to different technology streams is shared. The technologies that are deployed consist of: Volt Var control (VVC), electric vehicle integration, ad vanced metering infrastructure and demand response, and integration of distributed generation . In addition, enabling technologies that facilitat e the control of these resources—the distribution management system, telecommunications, and data management—are an integral part of the demonstration, as they are in any advanced distribution system. The technology fields mentioned above are, in part, financed by Natural Resources Canada through the Clean Energy Fund, as 4 technologies targeting GHG reduction. However, above and beyond the scope of the federal government’s programme, Hydro-Quebec is planning the integration of distribution automation and protection, with the go al of improving system reliability. At a strategic level, an important component of the demonstration project is to consider how these different applications overlap and to leverage technology inv estments, wherever possible. Results are presented on various elements of the de monstration, including field testing and validation testing on the distribution test line at the Hydro- Quebec Research Institute (IREQ). These results hel p to feed a discussion of initial leanings on the dep loyment of these different technologies and future initiatives focused on gathering additional knowled ge throughout the duration of the project. We conclude with a summary of the value of the project to date, as part of the overall smart distribution initiative.
Multi-layer inpainting on Chinese artwork
Digital inpainting uses spatial or frequency information to restore partially damaged/removed photos and artworks. Most restoration algorithms take a picture as a single layer. We propose a new approach, which subdivides a Chinese painting into several layers. Each layer is inpainted separately. The layer fusion mechanism then finds the optimal inpaint among layers, which are restored layer-bylayer. We apply the algorithm on Chinese and western drawing. The result shows a high PSNR value as well as a high user satisfaction. The demonstration of our work is available at: http://www.mine.tku.edu.tw/demos/inpaint.
