voltage control is one of the imperative issues in the smart distribution control system. while traditional distribution network is equipped with communication and monitoring equipment, the online voltage control can be perfectly achieved. with using these smart grid technologies, the distribution voltage control schemes should carry out intelligently and cover the undesirable effect of high pe...

Smart grid distribution and consumption communication network is one important part of smart gird communication network and the crucial technology field of smart grid. Smart grid distribution and consumption communication network due to its existing features such as large coverage, enormous number and irregular distribution of the network nodes and difficulty of network construction, has been l...

Power grid outages cause huge economical and societal costs. Disruptions in the power distribution grid are responsible for a significant fraction of electric power unavailability to customers. The impact of extreme weather conditions, continuously increasing demand, and the over-ageing of assets in the grid, deteriorates the safety of electric power delivery in the near future. It is this depe...

The knowledge of distribution grid models, including topologies and line impedances, is essential for monitoring, control protection. However, such information often unavailable, incomplete or outdated. increasing deployment smart meters (SMs) provides a unique opportunity to tackle this issue. This paper proposes two-stage framework modeling using SM data. In the first stage, network topology ...

the geographic distribution of astragalus l. (fabaceae) was analyzed using a database of 12377 geo-referenced observations. in the old world (including asia, africa and europe) there are ca. 2900 euploid species classified in 166 distinct sections. in this study using geographic information system (gis) by means of diva-gis (ver. 4) distribution map of some more important sections in the old wo...

The research on the grid size suitability is important to provide improvement in accuracies of gridded population distribution. It contributes to reveal the actual spatial distribution of population. However, currently little research has been done in this area. Many well-modeled gridded population dataset are basically built at a single grid scale. If the grid cell size is not appropriate, it ...
