Additionally, they can contribute to grid stability by providing voltage and frequency support. This paper includes a systematic review of recent advancements in gridforming converters with BESS (GFM BESS), its modelling and different control techniques to enhance the frequency stability of large-scale power system networks. Inertia in the power system is the energy stored in a large rotation part of a conventional synchronous generator which helps during any contingency like load imbalance or generator outage. The inertia of rotating parts under such conditions will help to stabilize the frequency. With an increasing share of IBRs, the lack of inertia by grid-forming converters is provided with a pulse width modulation controller linked with conventional inverters. This concept of virtual inertia by emulating the behaviour of GFM as a synchronous generator has been discussed with different virtual inertia-based control techniques with their comparative study. Also, challenges and open issues related to the high penetration of GFM BESS and the transition from islanded to a grid-connected mode of grid-forming converters are discussed.

To serve the industrial needs, the manufactured MMC should have homogenous distribution along with minimum agglomeration of reinforcement particles, defect-free microstructure, superior mechanical, tribological and corrosive properties. The techniques implemented to manufacture MMC highly dominate the aforementioned characteristics. According to the physical state of the matrix, the techniques implemented for manufacturing MMC can be classified under two categories i.e. solid state processing and liquid state process. The present article attempts to review the current status of different manufacturing techniques covered under these two categories. The article elaborates on the working principles of state-of-the-art manufacturing techniques, the effect of dominating process parameters and the resulting characteristic of composites. Apart from this, the article does provide data regarding the range of dominating process parameters and resulting mechanical properties of different grades of manufactured MMC. Using this data along with the comparative study, various industries and academicians will be able to select the appropriate techniques for manufacturing MMC.

In the framework of environment-friendly materials, natural fiber polymer matrix composites are in demand in the current years. Natural fiber reinforced polymer matrix composites (NFRPCs) involved massive attention to the industries and academia due to their excellent strength, modulus of elasticity, and Tribo properties. This article focuses on the application of natural fiber-reinforced composite materials in many engineering systems and the effect of different material parameters – like the length of the fiber, fiber weight fraction, fiber surface treatment, fiber orientation, etc., and different operating parameters – like load, speed, sliding distance, tempera ture, etc., on the friction and wear behavior of the NFRPCs. The different wear mechanisms and the principle used in wear test rigs are also presented, aiming to showcase a scope of composite as Tribo material and highlight further research directions to accomplish a comprehensive outline on the tribo behavior of various natural fiber-reinforced composite materials JOURNAL OF NATURAL FIBERS 2023, VOL. 20, NO. 1, 2172639 https://doi.org/10.1080/15440478.2023.2172639 Sun, 05 Feb 2023 00:00:00 GMT http://27.109.7.66:8080/xmlui/handle/123456789/2261 2023-02-05T00:00:00Z
