Reactive and Active Power Control of Grid WECS Based on DFIG and Energy Storage System under both Balanced and Unbalanced Grid Conditions
This paper focuses on improving the active and reactive power control of Wind Energy Conversion System (WECS) by employing the Battery Energy Storage System (BESS) and controlling the frequency and voltage regulation instantaneously. The proposed power control scheme is composed of two control loops so that they are implemented and designed for active power control and controlling the reactive ...
متن کاملModel Predictive Control of a Direct Fire Projectile Equipped With Canards
Launch uncertainties in uncontrolled direct fire projectiles can lead to significant impact point dispersion, even at relatively short range. A model predictive control scheme for direct fire projectiles is investigated to reduce impact point dispersion. The control law depends on projectile linear theory to create an approximate linear model of the projectile and quickly predict states into th...
متن کاملThe religious policy of Almoravid against Taşawwuf in Moroccan
From the middle of the fifth century, Almoravids became powerful with religious claims in Fareast Maghreb (Moroccan). Their internal and external policies for managing the country was based on Maliki religion. In addition to preventing other religions’ activity, Almoravids confronted Taşawwuf which had an important social status in that land and stopped their activities. The present study by ex...
متن کاملModifications to Walker-Anderson Model for Analysis of High-velocity Penetration of an Eroding Long-rod Projectile into Semi-infinite Concrete Targets
This paper presents a modified form of the Walker-Anderson (W-A) model for analyzing high velocity penetration of an eroding projectile into a concrete target in which the W-A model is improved by incorporating calculations for the plastic flow field of concrete in terms of its compressibility and strain rate sensitivity under severe pressure. With the changes to and calculations of plastic fie...
متن کاملTime-accurate Aerodynamic Modeling of Synthetic Jets for Flow Control
This paper describes a computational study undertaken to determine the aerodynamic effect of tiny unsteady synthetic jets as a means to provide the control authority needed to maneuver a spinning projectile at low subsonic speeds. Advanced Navier-Stokes computational techniques have been developed and used to obtain numerical solutions for the unsteady jet-interaction flow field at subsonic spe...
