The increasing integration of decentralized electrical sources is attended by problems with power quality, safe grid operation and grid stability. The concept of the Virtual Synchronous Machine (VISMA) [1] discribes an inverter to particularly connect renewable electrical sources to the grid that provides a wide variety of static an dynamic properties they are also suitable to achieve typical t...

The idea of microgrid, smart grid, and virtual power plant (VPP) is being developed to resolve the challenges climate change in 21st century, ensure use renewable energy electrical grid. For increasing demand for electricity, raising public consciousness about reducing carbon emission, microgrid established which transformed into a or grid with blessing modern communication systems, intelligenc...

In order to improve the level of new energy consumption and reduce dependence power system on traditional fossil energy, this paper proposed a bi-level optimization model for virtual plant member selection by means coordination complementarity among different sources, aiming at optimizing economy clean capacity combining it with time sequence load consumption. The method comprises following ste...

The functions of Poly(ADP-ribose) polymerase enzymes (PARPs) in general are best studied based on human PARP-1 (HsPARP-1). HsPARP-1 is well investigated because pharmacological modulation of its activity modulates DNA-binding of antitumor drugs [1]. In contrast to human PARP enzymes, the exact role of PARPs in plants remains to be elucidated. Different stresses activate plant PARP enzymes to me...

Doubly-fed induction generators (DFIG) constitute some of the larger units met in distributed generation (DG) with significant power control capabilities. These capabilities clearly become more important in modern grids where the aggregation of the individual DG units into larger structures, known as virtual power plant (VPP) concept, is utilized. A special role of DFIGs in the VPP frame is to ...

We present a method based on a 3D model converter to simulate the development of virtual plant. The converter is mainly used to import the plant organs which have fine details into the virtual plant development system, then communicating with the L-system to implement the simulation of the development of plants controlled by the physiology of plant. It improves the virtual effect that carried o...
