Currently, operating electrical power systems (EPS) is a complex task that relies on the experience of operators or strength algorithms developed for autonomous operation. The continuous operation EPS vulnerable to intentional cybernetic and physical attacks. With most significant extension distribution in EPS, transmission lines are exposed potential Before this, entire behavior changes, and, ...

In this paper, we present a new method to determine the optimal location and parameter settings of UnifiedPower Flow Controller (UPFC) for removing voltage violations and transmission lines overloading. UPFC isconsidered as the most powerful member of the FACTS devices, that it can control shunt and series power flow.This option gives to UPFC the power to control the voltage profile and transmi...

in this research, air sampling of workplaces was carried out by two methods (long - time and short - time). the mean formaldehyde concentration with long - time method in pathology labs, surgery and endoscopy sections were 0.96 0.25 and 0.13 ppm and with short - time method, 8 hours, was 3, 0.3 and 0.2 ppm. the mean formaldehyde concentration in pathology labs was above the standard values (tlv...

Recently, the use of wind farm in power systems is increasing rapidly it having a more noticeable impact on manner which these operate. When large farms are connected to system network, voltage stability concern as affects operation. This paper investigates location network when reactive limitation generators taken into consideration and reaches its maximum loading. An IEEE-14 bus test was modi...
