The large-scale shift of power flow after DC blocking will seriously affect the secure operation of the system.Furthermore, after DC blocking, the system uses different control objectives in different operation stages.Therefore, a two-stage coordinated control of AC/DC hybrid power system based on steady-state security region (SSR) is proposed.Firs
COVID-19 pandemic has changed our outlook toward the diagnosis and treatment of dermatological conditions.Accessibility to health care facilities has been jeopardized due to lockdowns, fear of contracting COVID infection, SHEA OIL maintaining social distance, and financial concerns.Vitiligo, one of the notorious chronic dermatoses, had a negative i
The complex flow field in the high-speed gearbox affects the transmission efficiency and performance of the transmission system by affecting the gear oil injection lubrication characteristics.Therefore, it is necessary to carry out research on the two-phase flow field ESTRO ADAPT and lubrication characteristics of high-speed gear oil injection cons
