Power system communication networks play a critical role in the operation and management of modern electricity grids. These networks serve as the backbone for the seamless exchange of data between various components of power systems, including generation plants, substations, and. There are a several types of communication media such as micro wave, radio system, fiber optic, etc. Power system management functions are primarily divided into three interrelated areas: There are 3 distinct types of telecommunication networks. 2) Various communication schemes used including power line carrier communication, fiber optic communication, satellite communication and. The large-scale integration of converter-interfaced resources leads to the power grid transfor-mation from voltage-source-dominated to voltage-current-source-composite, which also raises new challenges to model and analyze the system synchronization.
