Welcome to the Lecture: Plug-and-play operation and optimal power sharing in renewable based grids: distributed control and grid code formulations

Abstract: Modern power grids are currently undergoing significant transformations with an increasing need for improved efficiency and also for distributed control policies with a plug-and-play capability. We consider in this talk the problem of designing distributed control schemes in power networks such that stability and an optimal power sharing can be guaranteed. Local conditions on the bus dynamics and corresponding control design protocols are presented which allow stability for the entire network to be guaranteed, while also leading to convergence to an optimal power allocation. Extensions are also presented in more advanced configurations of converter based grids, hybrid AC/DC networks, and discuss also local conditions that lead to optimal control interpretations that can enhance performance.
