TL;DR: In this paper, a maximum power point tracking (MPPT) design for a photovoltaic (PV) system using a grey wolf optimization (GWO) technique is presented, where the problem of tracking the global peak (GP) of a PV array under partial shading conditions (PSCs) is attempted employing the GWO-based MPPT technique.

TL;DR: From the obtained results, it is confirmed that the proposed MPPT provides superior tracking performance in any weather conditions compared to both GWO and PSO+PO-based MPPT algorithms.

TL;DR: The JAYA is a new optimization tool whose performance is independent of the algorithm-specific control parameters and overcomes the limitations of others in terms of attaining global optima with reduced computational effort.

TL;DR: The proposed ensemble Kalman filter (KF) approach to estimation of harmonics, interharmonics, and subharmonics in a distorted power system signal exhibits superior estimation performance in terms of tracking time and accuracy as compared to performances of some of the existing techniques such as recursive least square, recursive least mean square, and KF algorithms.

TL;DR: In this paper, an active crowbar protection (ACB_P) system is proposed to enhance the Fault-ride through (FRT) capability of DFGs so as to improve the power quality of the system.
