Abstract
Higher percentages of wind generation are anticipated to reduce effective inertia on the electric power grid, presenting challenges to electromechanical stability. Two technologies will help mitigate these stability problems: (i) advanced control systems on wind turbines, exploiting Phasor Measurement Units (PMUs), and (ii) deployment of controllable energy storage. This paper extends state feedback-based, centrally-coordinated control design for energy storage and wind generation to consider distributed, observer-based implementations. Establishing that a local bus PMU measurement at each controller is inappropriate, we demonstrate the feasibility of limiting each local controller to a very small set of remote PMU measurements. An approach is developed that characterizes the practical degree of observability achieved on a subspace of lightly damped electromechanical modes of interest. In a representative power system model, the measurement selection methodology and local observer design is shown to yield control performance very closely approximating that obtained in the centralized, full state feedback case.
