• Security margins methods are significantly affected by the load dynamics in a system. Induction motor loads and fast restoring especially important. based on static assessment may provide overly optimistic estimations. dynamic time-consuming, but more accurate. The post-contingency loadability limit (PCLL) secure operating (SOL) two main approaches used when computing security of an electric ...

In this paper, the Static Var Compensator (SVC) has been used to improve dynamic behaviour of power system. To do this, a new objective function is formulated considering power loss reduction, voltage profile improvement and loadability margin decrease. Other contribution of this research is proposing a novel structure for Particle Swarm Optimization (PSO) algorithm through modifying the initia...

With the recent trends towards deregulating power systems around the world, transfer capability computation emerges as the key issue to a smoothly running power market with multiple transactions. Enhancement of available transfer Capability (ATC) is an important topic in current deregulation environment considering loop flows and heavily loaded lines. The thermal limits of transmission lines, v...

Agilent Prep reversed-phase columns with different diameters displayed the nearly linear scaleup for the gradient separation of corticosteroids. The loadability of the columns was quite good with as much as 8 mg of total corticosteroid injected onto a 4.6-mm column and 320 mg onto a 30-mm column.

-In this paper, multi-objective optimal placement (MOOP) of multi-type flexible AC transmission systems (FACTS) devices for Thailand power system is proposed. Four types of FACTS devices are used: thyristor-controlled series capacitor (TCSC), thyristor-controlled phase shifter (TCPS), unified power flow controller (UPFC), and static var compensator (SVC). The problem is decomposed into the opti...
