This paper addresses the challenges in Voltage Source Inverter (VSI) systems connected to weak grids, where frequent impedance changes lead to instability and power quality issues. This research studies how changing grid impedance affects current distortion and the stability of a VSI. It proposes the stability analysis of a single loop controller a...
In this study the grid impedance-based stability is concerned and improve the inverter stability for lower-voltage distribution networks. Also proposes the optimal filter and controller parameters for weak grids, considering IEEE std 519. The two methods are employed to enhance the inverter stability: (A). Changing the output impedance of the VSI b...
—The fundamental principle of integrating a voltage
source within an electrical network to enhance voltage control and promote network stability remains a core tenet of
electrical engineering. In scenarios characterized by weak grid
conditions, where voltage fluctuations and instability are prevalent, a strategic solution involves the synergistic d...
Author: Harendra Pal Singh-ABSTRACT-In a recent trend for controlling of most of the industrial loads is mainly based on semiconductor devices which cause such loads to be more sensitive against power system disturbances. Thus, the power quality problems have gained more interest recently. This paper presents a review of some of the disturbances, o...
The term 'power quality' related to the stability of voltage and frequency and the elimination of different types of electrical noise, like harmonic distortion and flicker, present in the system. Although there may be many more operational conditions affects the operation of the wind power plant. The plant may be grid connected or not, but it's nec...
