A Game-Theoretic Framework for Distributed Voltage Regulation over HVDC grids

In this paper we propose a non-cooperative game-theoretical framework to design the strategic behaviour of buses involved in a HVDC grid that are connected to renewable resources. This framework takes under consideration voltage stability issues as well as economic factors when the current carried by the power lines is constrained. In order to reach an agreement in the decisions of the buses, an iterative distributed Nash equilibrium seeking algorithm is implemented. Existence and stability conditions for the equilibrium are introduced for the unconstrained case and simulations show the robustness of the algorithm for the constrained scenario.
