The conventional generators are equipped with power system stabilizers (PSS) to damp oscillations that follow disturbances. inclusion of renewable energy sources within the existing systems requires further investigations enhance performance PSS. Several control strategies have been being used design In this paper, model predictive (MPC) is investigated be as a It uses numerical optimization al...
nowadays in trade and economic issues, prediction is proposed as the most important branch of science. existence of effective variables, caused various sectors of the economic and business executives to prefer having mechanisms which can be used in their decisions. in recent years, several advances have led to various challenges in the science of forecasting. economical managers in various fi...
Power factor correction of boost converter is done by using predictive control strategy. In this paper predictive control algorithm is presented based on this algorithm all of the duty cycles required to achieve unity power factor in one half line period are calculated in advance by proportional Integral (PI) controller, the simulation results show that the proposed predictive strategy for PFC ...
Recently, Brushless Cascaded Doubly Fed Induction Generator (BCDFIG) has been considered as an attractive choice for grid-connected applications due to its high controllability and reliability. In this paper, a Finite Control Set Model Predictive Control (FCS-MPC) method with active and reactive power control capability in grid-connected mode is proposed for controlling the BCDFIG in a way that...
the aim of the current study was to investigate the relationship among efl learners learning style preferences, use of language learning strategies, and autonomy. a total of 148 male and female learners, between the ages of 18 and 30, majoring in english literature and english translation at islamic azad university, central tehran were randomly selected. a package of three questionnaires was ad...
the efficiency of induction motors decreases at light loads. efficiency optimizer control systemsadjust the motor flux value to achieve the best efficiency in a wide range of load variations. reduced fluxoperation has some other benefits such as power factor improvement and torque ripple reduction. the latter isan important issue in a direct torque controlled induction motor drive. in this pape...
