This article determines the optimal location of accurate high voltage direct current (AHVDC) tie-line and energy storage devices (ESD) on system dynamics of three-area thermal-precise wind turbine systems (PWTS) under the deregulated scenario. The thermal system with an AC tie-line is integrated with PWTS. AHVDC tie-line. and ESD like redox flow battery. https://allfixelectricales.shop/product-category/roasting-rack/
