“…The "929-1988-IEEE Recommended Practice for Utility Interface of Residential and Intermediate Photovoltaic (PV) Systems ( 1987)" [28] has stated that the total harmonic distortion is defined as the ratio of the square root of the sum of the squares of the rms values of the analyzed signal to the rms value of its fundamental term. This value is always given in percent as indicated in (1).…”

<span lang="EN-US">This paper is devoted to the state of the art in photovoltaic (PV) conversion chains and their architectures. Two major characteristics are considered to classify these chains. These are the galvanic isolation and the number of stages; characteristics generally localized around the DC-AC converter (inverter) at the end of the PV conversion chain. Therefore, this paper deals with a comprehensive review of the different inverter topologies that can be integrated into PV conversion chains, distinguishing between the transformer based and the transformer-less conversion chains. The paper demonstrates that to this date, transformer-based inverters are very common and widely used, have a long record of accomplishment as a component of solar energy systems, in particular for residential applications because of their greater efficiency, smaller size, and lower costs. Nevertheless, transformer-less chains are touted with some problems and shortcomings. Moreover, solar energy storage devices, wireless charging systems in stations and along the highways require the re-examination of the existing solar PV conversion chains, their architectures and possibly new conversion chains suitable for all distributed generation including electric cars and storage devices.</span>

“…Multilevel topologies offer better output voltage capability, lower voltage stress on switches, lower dv/dt, higher output voltage quality, and higher efficiency as compared to conventional two-level inverters [5]. The flying capacitor, cascaded H-bridge (CHB), and neutral point clamped multilevel converter topologies are the most popular conventional MLIs [6], [7]. The CHB has gained popularity for high-power and power-quality applications because of its simplicity and versatility.…”

Storage technologies are essential for preserving the renewable grid power balance between generation and consumption. In this research, a solid-state transformer (SST) based T-type multilevel inverter (MLI) is proposed for the medium/high voltage integration of large-scale battery energy storage (BES). For any turn ratio, the proposed SST-MLI generates 25 levels with fewer switching devices and SSTs. A novel dynamic phase shift controller (NDPSC) is also being developed for the proposed BES system. The NDPSC controller regulates active and reactive power by maintaining the battery's health. The NDPSC controller uses two gain control factors tuned to produce a fast response without overshooting. The proposed battery storage system's dynamic behavior is simulated in MATLAB/Simulink for various active and reactive power variations and experimentally validated in a low-power laboratory prototype system.
