In this paper, particle swarm optimization (PSO) based maximum power point tracking (MPPT) for PV system is presented which is interrelated with other control schemes such as synchronization with grid and current control. All these schemes for utility-scale photovoltaic system are realized in a single-stage for the high efficiency and simple power converter topology. The MPP changes with variation...
Prony analysis and matrix pencil method have been widely used for monitoring power system oscillations. In this paper, a performance study has been made on Prony analysis and matrix pencil method, which utilize single signal, as well as multiple signals, to estimate the dominant modes of oscillations. The performance of the two methods are evaluated on actual data obtained from PMUs interfaced to...
This paper proposes a method based on noise space decomposition (NSD) for the identification of low frequency oscillations in power systems. The proposed method uses a median filter to reduce the variance of the estimated modes. The signal utilized for estimating the modes is the power signal obtained from phasor measurement units (PMUs). The results with the proposed method has been compared with...
This paper deals with implementation of an Improved Prony algorithm, based on median filter, in estimating the low frequency modes of power system oscillations. The signal used for estimating the modes are the power signal obtained from phasor measurement units (PMUs). The comparison of the proposed method has been carried out with conventional Prony based method on a synthetic test signal at different...
