<p>Dynamic voltage restorer (DVR) is a series active filter device that is used to protect sensitive loads from power quality issues such as voltage sag, swell, harmonics or disturbances. This implies that the DVR is capable to mitigate power quality disturbances at load terminal. Harmonic is a major power quality problem polluting distribution network causing the end-user equipment to fail operating due to the occurrence of disturbances in voltage, current or frequency. This paper discusses on the DVR used as the proposed technique to mitigate the voltage sag and swell in a distribution network connected with energy storage system and mini-hydro turbine system.</p>

Green manufacturing concept has become a cutting edge in the field of sustainable machining. The prime objective of the philosophy is to find a technique in machining or material removal processes that are environmentally friendly, with minimal wastage, energy efficient and optimal condition for the machining processes. This review paper discusses the significance of textured novel cutting tools, is one of the promising technologies and process. It discusses the Dry Machining process to capture green sustainable manufacturing practices. The study may answer of how it stands among other methods including minimum quantity lubrication and nano fluid lubricant. This paper also presents the importance of advanced manufacturing tools to match the sustainable future needs with an idea of proposed methodology to conduct a research on textured novel cutting tools for sustainable machining.
