The imposed short non-stationary disturbance with cyber-attack severely threaten the safety of power grid. Therefore, dynamic security control for power grid which drive the system to normal steady state is a crucial demand of power industry. To deal with dynamic security problem of power grid, we investigate the theory and methodology of power grid dynamic energy and security control with energy function and game theory under cyber jamming attack for enhancing the grid security and the resilience of dynamic security control system under cyber-attack. We firstly develop an energy function according to power system dynamic mechanisms, and convert security problem to stability problem by introducing overload energy and control energy. The critical point on energy surface is enhanced so as to implement security control and reducing the computational complexity on control. The sparse relation of control system structure is characterized by sparse blocks, the power grid dynamic security is measured by analyzing invariant set of energy polyhedron, so that the utility of game is obtained to establish imperfect game model for depict the human purpose. By solving the game model, we can optimize the structure and strategy of security control system, enhancing the resilience of security control system under cyber jamming attack. This proposal not only offer a new way to strengthen the dynamic security of power grid, but also promote this new application of control theory in power grid.
