In order to accurately describe the influence of the random factors in distribution systems on the probabilistic load flow (PLF), a PLF method of distribution system containing wind power and EVCL based on a stochastic response surface method (SRSM) is put forward. The proposed method can sufficiently consider the randomness of wind speed as well as uncertainty of basic load and EVCL. Furthermore,...
To improve the accuracy and availability of the data acquisition system from wind farms, this study proposes to use the adaptive detection methods for effective detection abnormal wind speed. In allusion to characterization of the abnormal value was not obvious, choose Auto Regressive Integrated Moving Average to predict wind value of the current moment to obtain residual sequence. In order to reduce...
To calculate probabilistic load flow of distribution system containing distributed generation (DG) and electric vehicle charging load (EVCL), at first the effect on load flow for distribution system after connecting DG and EVCL is analyzed, and the stochastic characteristics of power output of wind generation and photovoltaic power generation as well as basic load and EVCL are researched, meanwhile...
In order to solve the problem of voltage drop by use of serial compensation, real-time compensation signal generation algorithm is designed in order to provide reference input signal to DVR control system. The algorithm uses iterative filtering to generate the reference waveform of the sinusoidal and orthogonal in real time and provides a basis for pqr transformation. In the pqr coordinate system,...
