Frequency Support (FS) through the Multi-Terminal HVDC (MTDC) grids is become
obligatory by most of the Transmission System Operators (TSOs). Providing this support
without any communication between converter stations is challenging. In the literature,
researchers try to obtain the FS from the dc grid in a communication-free manner to improve
the stability and reliability of the AC surrounded MTDC (AC-MTDC) grids. Moreover, in most
