Company History

QNE, an independent high-tech startup company, was founded in early 2007 by a team of highly skilled Embedded Systems professionals as they identified the need for new, scalable and future-proof technologies for tomorrows clean power supply incorporating decentralised energy resources in smart grids, providing balance power by intelligently coordinating "prosumers" and "prostormers" using the Internet as the networking technology.

QNE’s cost-effective, internet based procurement equipment to unleash the profitability potential slumbering in numerous virtual power plant candidates – such as CHP, renewables and cooling systems – provides key technological advantages for optimised profitability margins for industry, services and utility companies. This is why we researched, engineered, and developed our Energy Procurement Technology – ETProxy.

In order to upgrade distribution power grids for accepting bidirectional power flows, accurate real-time information in regard to actual, instantaneous power flows (bidirectional and including active as well as reactive power flow) is imperative for the effective operation of distribution grid automation. QNE’ Smart Grid Sensors (SGS) were developed in 2008 and brought to maturity in early 2010 to provide exactly this functionality. Electronic current and voltage transformer data are digitally processed directly in the sensor devices and made available as sampled values and derived statistical values in IEC 61850 format on their ISO/IEC 8802-3 (Ethernet) interfaces. Powerful QNE KeyMaker© Tunnel Technology (either a layer 3 virtual network software and/or a layer 1 virtual network hardware) provides seamless integration to augment IEC 61850 Automation to integrate sampled values from several decentralised locations into virtual bays, basically allowing you to operate distributed virtual bus bars in distribution grids.

QNE Smart Grid Sensors have been successfully deployed in the extensive field test Project eTelligence in Cuxhaven, funded by the German Federal Ministry of Economics and Technology (approx. 10 Million Euros) and operated by

and others:

»We are currently putting up measurement equipment that allows us to “look into” the grid at low and medium voltage levels in real time. This information will be used to analyze and understand, as well as actively control the distribution system. E.g., the reactive power of CHP units shall be used to actively control the voltage gradients on the medium voltage lines. Furthermore, dynamic protection schemes will be developed and tested.« (Source: EPRI).



Additionally, QNE Smart Meters are deployed (non-exclusively) in the eTelligence Project as well to obtain active power grid information from the household endpoints and automate smart metering and consumer feedback systems over the Internet using QNE µSpyDER Technology:

»Regarding the household customers, 2000 households will be equipped with latest smart meter technology and different feedback systems (paper, internet portal, iPod touch) to provide consumers with information about their electricity consumption.« (Source: EPRI).
