The electron energy distribution functions(EEDFs)are studied in the planar-type surface-wave plasma(SWP)caused by resonant excitation of surface plasmon polaritons(SPPs)using a single cylindrical *** plasma characteristics can be considered as a bi-Maxwellian EEDF,which correspond to a superposition of the bulk low-temperature electron and the high-energy electron beam-like *** beam component energy is pronounced at about 10 eV but the bulk part is lower than 3.5 *** hot electrons included in the proposed plasmas play a significant role in plasma heating and further affect the discharge chemistry.

This paper establishes the model of wind speed correlation (WSC) by inverse Nataf transformation. The impacts of WSC on distribution network operation and maximum installed capacity of wind power are investigated by Monte Carlo simulation and chance constrained programming method. A new definition of wind power penetration is proposed. Finally, conclusions are duly drawn.

Integrating large amount of low-inertia and intermittent renewable generation into the power system has increased the occurrence probability of power system imbalance brought about by large disturbances in short time scale and reduced the control capability of the power system under those disturbances. The continually increased electric vehicles (EVs) connected to the power grid may be capable of responding to those disturbances and contributed to the power balance by utilizing the fast-response, continuously regulating and power decoupling control capability of the power electronic charging interfaces. In this paper, different control schemes have been proposed to respond to the disturbances originated from distribution systems and the transmission systems respectively by regarding the electric vehicles as power support resources and considering the characteristics of the distribution network. A typical 11-kV 38-node system has been presented and tested to validate the effectiveness of utilizing the electric vehicles as power balance control resources and the related control schemes.
