Voltage Stability Study based on New Evolutionary Algorithm
Abstract: This paper describes a PSO optimization algorithm for voltage stability study and its enhancement based on proximity and mechanism analysis. This theorem is implemented based on Gershgorin’s Circle Theorem. The control variables responsible for enhancing the voltage stability limit are generator bus voltages at PV buses, the taps of On-Load –Tap-Changing Transformer. (OLTC), change in reactive power etc. The objective function of proposed algorithm is to maximize the minimal diagonal …

A Precise Clock Synchronization Algorithm in Network
Abstract: To execute a task in a synchronized manner in a distributed setting, we need the common idea of time. To accomplish this intention, clock synchronization is conceptualized. Clock drifting is an intrinsic property of a clock, which necessitates the synchronization. A network consists of nodes, which may execute appropriately or behave badly. The mischievous node may pose difficulty in clock synchronization. We require a method to ease the effect of …
