In this study, a fuzzy probability-based Markov chain model is developed for forecasting regional long-term electric power demand. The model can deal with the uncertainties in electric power system and reflect the vague and ambiguous during the process of power load forecasting through allowing uncertainties expressed as fuzzy parameters and discrete intervals. The developed model is applied to...

empowering of terrorist groups in the middle east is the product of numerous reasons. one of the most important of these reasons is the competition between regional powers and their use of the leverage of terrorist groups in order to put pressure on each other. furthermore, immature and wrong policies of great powers like: the united states in militarization of the region have provided new just...

Zhangjiakou regional network belongs to the Jibei power grid in Northern China and locates at the midway of the power transmission corridor from Inner-Mongolia to the rest of Jibei power grid. Zhangjiakou regional network consists of several area networks connected to the main network through 500kV stations. In recent years, renewable energy in rural areas has developed rapidly and electrified ...

INTRODUCTION Correlated low-frequency fluctuations of resting-state functional magnetic resonance imaging (rsfMRI) signals have been widely used for inferring intrinsic brain functional connectivity (FC). In animal studies, accurate estimate of anesthetic effects on rsfMRI signals is demanded for reliable interpretations of FC changes. We have previously shown that inter-regional FC can reliabl...

Short-term wind power forecasting is recognized nowadays as a major requirement for a secure and economic integration of wind power in a power system. In the case of large-scale integration, end users such as transmission system operators focus on the prediction of regional or even national wind power up to 48 hours ahead. At a European level such predictions will be required in the future for ...

The paper at hand presents an analytical framework to assess the relative power of both ‘mainstream’ theories of regional integration and theories of the New Regionalism for the explanation of regional integration in Southern Africa. It is argued that the explanatory power of theories of both theoretical camps can be tested by comparing their assumptions with regard to four criteria of analysis...

Most of the ac-ac converters used in home-appliances are based on single-output dc-link inverters, which provides a cost-effective and straight-forward solution. However, this twostage power conversion decreases power density and efficiency. Direct ac-ac conversion has been thoroughly studied in the past. However, the complex control scheme and higher cost has prevented it from being used in lo...

Power quality has become an important factor in power systems. The main causes of a poor power quality are harmonic currents, poor power factor, supply-voltage variations, etc. To mitigate power quality problems, we have various equipments like active filter, passive filter, unified power flow controller and unified power quality conditioner etc. Among from them unified power quality conditione...
