IEEE has made two standards announcement. The first involves the ratification of IEEE 1815 Distributed Network Protocol (DNP3) standard for electric power systems communications. This new standard, which is said to improve device interoperability and strengthen security protocols, was fast-tracked for completion and was delivered in only seven months. Scheduled for final publication in July 2010, IEEE 1815 is expected to play a significant role in the development and deployment of smart grid technologies.
The accelerated deployment of smart grid technologies, as well as thousands of new and legacy device installations in process automation settings like the electric utility, energy, and water industries, dictated the need for IEEE 1815.
IEEE 1815 is said to be a robust, multi-layered protocol which specifies an agile, forward-looking architecture enabling better optimized and more secure information gathering, exchange, and use, particularly in supervisory control and data acquisition (SCADA) systems. Expanding on widely used industry protocols, the comprehensive standard also preserves previous significant infrastructure investments by remaining backward compatible with existing object models, while incorporating emerging smart grid and other new technologies.
The second standards announcement from IEEE relates to the notice of draft standard IEEE P1547.8 for establishing a common technical platform for distributed resources interconnection applications. The proposed standard expands upon IEEE 1547, while incorporating industry and National Institute of Standards and Technology (NIST) recommendations for improved interconnection performance functionality. It also addresses energy storage challenges coming into play across the distributed resources and smart grid industries. Ratification of IEEE P1547.8, which is sponsored by the IEEE Standards Coordinating Committee 21 (SCC21), is targeted for calendar year 2012.
More specifically, IEEE P1547.8 provides greater support for intermittent renewable energy sources, and more flexible use of inverters such as those found in home solar power systems, enabling easier and more robust connections to the grid. It also addresses energy storage devices, hybrid generation-storage systems (ES-DER), and ES-DER aspects of plug-in electric vehicles (PEV), as well as taking into account a variety of industry-driven recommendations. IEEE P1547.8 is targeted to distributed resource owners, interconnection contractors, equipment manufacturers, system integrators, area electric power system owners, planners and operators, and regulatory agencies.
A Tokyo company, Miraisens Inc., has unveiled a device that allows users to move virtual 3D objects around and "feel" them via a vibration sensor. The device has many applications within the gaming, medical, and 3D-printing industries.
In the last few years, use of CFD in building design has increased manifolds. Computational
fluid dynamics is effective in analyzing the flow and thermal properties of air within spaces. It can be used in buildings to find the best measures for comfortable temperature at low energy use.
