This paper deals with the problems related to power stability issues in the isolated wind-solar based renewable energy system. The stability issues in such system are produced mainly due to unbalanced loading, distortion of load current and intermittent nature of renewable energy sources. To overcome these problems, A voltage source converter (VSC) is used in […]
This paper proposes a unified neural network controller in development of series active power filter. Three major power quality problems considered for this work are harmonics, sags, and interruptions, and dealing with all of them really needs effective unified algorithm which could adapt with variation of signals. Therefore, Levenberg-Marquardt (L-M) back propagation algorithm is introduced […]
Nowadays the demand for receiving the high quality electrical energy is being increasing as consumer wants not only reliable but also quality power .The usage of automated equipment are increasing and far more susceptible to disturbances compare to the previous generation equipment and information systems. With the deregulation of the electric power energy market, the awareness […]
In this paper, a new fuzzy controller for a three-phase and three-wire distribution static compensator (DSTATCOM) is presented to improve power quality. A three-leg voltage source converter based DSTATCOM is used to control the harmonic currents for two nonlinear loads. In this control system, the gate pulses for IGBT switches are provided by a hysteresis […]
This article describes the use of a sliding mode controller (SMC) in conjunction with an integral (PI) controller for a MLI based DSTATCOM to balance dc side voltage, control a cascaded H-bridge inverter, and compensate for power quality issues related to current harmonics. Several benefits come with using SMC for DSTATCOMDC link voltage regulation, including […]
