Renewable energy has the characteristics of low carbon and environmental protection compared to traditional water thermal power, but it also intermittency uncertainty that power does not have. These make inertia system increase, which greatly affects frequency stability grid. To solve such problems, participation demand-side resources (DSRs) in dispatch systems become a viable solution.However,...

Photovoltaic (PV) system as one part of distributed energy resources is becoming an alternative for low and medium distribution network microgrid. By the reason a wide implementation power electronic non-linear loads, harmonics distortion main problems systems. There are several filter types to mitigate harmonics. The passive distinguished by its simplicity economical options from another filte...

The detection of series arc faults using fault current is difficult to overcome the influence load types, making it establish a unified criterion. In contrast, since voltage waveform point less affected by types and basically square wave shape, which provide conditions for constructing terms information, distortion on load-side caused transition edge provides position information edge, its pola...

Centralized power generation by self owned plants of high energy consumption enterprises will lead to insufficient peak shaving capacity the grid. Once have operational problems, they easily large-scale blackouts, which a great impact on supply reliability. The national electric system reform opinion points out that regulation focus ensuring balance and demand in grid should be shifted from sid...

Social networks, web portals or e-learning platforms produce in general a large amount of data everyday, normally stored in its raw format in log file systems and databases. Such data can be condensed and summarized to improve reporting performance and reduce the system load. This data summarization reduces the amount of space that is required to store software data but produces, as a side effe...

In the paper load shedding time analysis in Buildings Energy Management Systems are presented. Influence of the communication system structures on the data exchange duration is analysed and its results for a few communication structures are presented. Streszczenie. W artykule przedstawiono analizy czasowe operacji redukcji obciążenia w budynkowych systemach zarządzania energią. Przeanalizowano ...

Multimedia applications require continuous delivery of time-dependent data. In best-effort systems where no resource reservation is possible, adaptation strategies are necessary in case of high system load. We propose an adaptation framework for a client-pull architecture where continuous data are requested and buffered by the presenting client. The current client buffer utilization is used as ...
