Abstract In recent times, multilevel inverters (MLIs) are gaining popularity for grid integration of distributed power generation sources. In this paper, a proportional‐resonant (PR) controller based on current control logic is proposed for a singl

Abstract The constant growth of distributed energy resource (DER) in the electric power system (EPS) is a reality on account of some aspects, for example, technical, financial, environmental. The insertion of DERs can be positive, providing ancillary

Abstract In this study, a network mode energy (NME) method is used to analyse the low‐frequency oscillation (LFO) of a power system with a high penetration of a permanent magnet synchronous generator (PMSG). This method is also utilized to determin

Abstract Due to the negative impact of a highly stochastic wind power fluctuation on the power quality and stability during high penetration of wind power in power systems, there is growing interest in power smoothing and energy redistribution in win

Abstract The conventional selective harmonic elimination method of random pulse width modulation (RPWM) is only suitable for the two‐level inverter. Furthermore, when the harmonics below 6 kHz are selectively eliminated, it is easy to cause a low a

Abstract Improving network power quality through harmonic reduction requires recognition of Harmonic Sources (HSs) to drive them to compensate their harmonics. This paper proposes a new method for equitable distribution of the Harmonic Compensation C
