A Hybrid Coordinated Design Method for Power System Stabilizer and FACTS Device Based on Synchrosqueezed Wavelet Transform and Stochastic Subspace Identification

引用

Journal of Modern Power Systems and Clean Energy 2021年第4期9卷 910-918页

作者： ayda Faraji Ali Hesami Naghshbandy Arman Ghaderi Baayeh Department of Electrical Engineering Faculty of EngineeringUniversity of KurdistanSanandajKurdistanIran

The occurrence of low-frequency electromechanical oscillations is a major problem in the effective operation of power systems. The scrutiny of these oscillations provides substantial information about power system stability and security. In this paper, a new method is introduced based on a combination of synchrosqueezed wavelet transform and the stochastic subspace identification (SSI) algorithm to investigate the low-frequency electromechanical oscillations of large-scale power systems. Then, the estimated modes of the power system are used for the design of the power system stabilizer and the flexible alternating current transmission system (FACTS) device. In this optimization problem, the control parameters are set using a hybrid approach composed of the Prony and residual methods and the modified fruit fly optimization algorithm. The proposed mode estimation method and the controller design are simulated in MATLAB using two test case systems, namely IEEE 2-area 4-generator and New England-New York 68-bus 16-generator systems. The simulation results demonstrate the high performance of the proposed method in estimation of local and inter-area modes, and indicate the improvements in oscillation damping and power system stability.

Objective: The use of traditional medicine and complementary alternative medicine(TM/CAM) derived from herbal remedies or natural supplements is increasing worldwide, but there are limited data on the use of TM/CAM during pregnancy. Iran has various ethnic populations, and the usage of TM/CAM by the different ethnic groups has not been researched. The aim of this study is to understand the use of TM/CAM modalities in pregnant women of different ethnic groups in southern ***: This study was conducted in primary health care centers in Khuzestan Province, Iran, from May to August, 2016. A semi-structured valid questionnaire was used to gather information in pregnant women(n = 170).Results: About 46.5% of women in this study used TM/CAM during previous pregnancies. The majority(67%) of study participants were Arab. The Arab population showed increased use of TM/CAM during pregnancy(P = 0.014). Women with complications in former pregnancies had significantly higher incidence rate of TM/CAM use(65.8%) compared to the other group(39.6%)(P = 0.001).Conclusion: Understanding TM/CAM use and the associated factors in different ethnic groups of pregnant women will benefit the evaluation of the proper health policies and mother-infant health programs. This study contributes to the growing literature on TM/CAM, ethnic diversity and pregnant women.

Geochemical, Sedimentological and Mineralogical Characterization of Surficial Sediments in Eynak Marsh (North of Iran)

引用

Open Journal of Geology 2016年第7期6卷 640-659页

作者： ayda Hazermoshar Razyeh Lak Mohammad Reza Espahbood Nader Kohansal Ghadimvand Reza Farajzadeh Department of Earth Science Islamic Azad University North Tehran Branch Tehran Iran Research Institute for Earth Sciences Geological Survey of Iran Tehran Iran Department of Earth Science Kharazmi University of Tehran Tehran Iran

A multidisciplinary study of the sedimentology, geochemistry and mineralogy has been conducted to understand the linkage between marsh and alluvial sediments and also their potential sources in Eynak marsh, North of Iran. The influence of the upstream potential sources on recent sediment geochemistry has been discussed based on geochemical, sedimentological and mineralogical results. A spatial grain size distribution study was carried out to investigate the hydrodynamic and deposition system of the marsh. So, the surficial sediment sampling was carried out to describe the sedimentological parameters and elemental geochemistry of sediments in Eynak marsh. Mineralogical complexes are mainly made up of felsic minerals such as quartz, calcite, feldspar, pyrite, mica, and clay minerals (in very low values) indicated by high amounts of Al, Ca, and Ni. As expected, the mineralogy of sediments is controlled mainly by the rock formations. Also sediment textures are controlled by the hydrodynamic condition in the marsh. So its distribution has been influenced by distance from the entrance sediments to Eynak marsh. The results showed that there are no enrichments related to fine grain sediment distributions. An association of Al with the trace elements such as Sc, Y, La, Ce, and Zr indicates that their distributions are mainly controlled by the felsic rocks in the upstream. On the other side, due to the waste water entrance to the marsh, Ni and Pb concentration could be under the effects of anthropogenic activities around the marsh. Results represented high values for Mn concentration (min 462, max 1784 and average 1037 ppm) and it showed a significant correlation with Ca, Sr, and Mg. A redox habitat and constantly calm hydrodynamic circumstance in the study area, likely cause high concentration of Ca, Sr, and Mg, and Mn. And they are representing negative correlations with some elements such as Al, Be, Fe, K, and Na.
