ABSTRACT This paper concerns frequency regulation performance in power systems with a high level of wind generation penetration. As wind generation becomes a significant portion of total energy production, wind power variability will cause system frequency to deviate from nominal value. Short-term wind power fluctuations are characterized by frequency spectra. This information is used together with robust control, specifically the H method, to synthesize new governors for conventional plants in order to better attenuate frequency deviation caused by wind power fluctuations. A reduced-order controller is obtained based on Hankel singular values. Simulation results show the effectiveness of the H controller. This work suggests several directions for further research.

    ABSTRACT: An H∞-based decentralized robust control approach is proposed in this paper to integrate energy storage into primary frequency control and to address increased frequency deviations introduced by renewable energy sources (RESs). The proposed new primary frequency control design is formulated as an H∞ minimization problem with decentralized static output feedback. The three objectives are: 1) to minimize frequency deviations; 2) to minimize the use of energy storage devices; 3) to minimize the ramp rates required from conventional generators. A so-called frequency separation objective is achieved, i.e. low frequency variations of the RES power fluctuations are balanced by the conventional generators while the high frequency variations are compensated by the storage device. The detailed derivation of an interconnected power system model based on component-level models is provided to facilitate the control design. In order to evaluate the performance loss due to controller decentralization, a centralized counterpart of the proposed approach is presented and tested as well. Simulation results on the WECC 9-bus test system illustrate the performance of the proposed control.

    ABSTRACT: This paper deals with fault-tolerant controller design for linear time-invariant (LTI) systems with multiple actuators. Given some critical subsets of the actuators, it is assumed that every combination of actuators can fail as long as the set of the remaining actuators includes one of these subsets. Motivated by electric power systems and biological systems, the goal is to design a controller so that the closed-loop system satisfies two properties: (i) stability under all permissible sets of faults and (ii) better performance after clearing every subset of the existing faults in the system. It is shown that a state-feedback controller satisfying these properties exists if and only if a linear matrix inequality (LMI) problem is feasible. This LMI condition is then transformed into an optimal-control condition, which has a useful interpretation. The results are also generalized to output-feedback and decentralized control cases. The efficacy of this work is demonstrated by designing fault-tolerant speed governors for a power system. The results developed here can be extended to more general types of faults, where each fault can possibly affect all state-space matrices of the system.

    ABSTRACT: As wind generation becomes a significant portion of total energy production, wind power variability will introduce more variability in system frequency. This paper presents a method to improve primary control for frequency regulation in large-scale power systems with high wind power penetration. To assure system stability, a passivity-based framework is developed for power systems by introducing a storage function derived from the entropy of individual generators. Tellegen's theorem is invoked to derive the storage function for the entire power network. Given the network parameters and the point of interconnection of the wind farm, a single generator is selected to balance wind power fluctuations. A passive H<sub>∞</sub> controller is synthesized for the selected generator by using a passive reduced-order model of the large-scale power system. Simulation results of a 9-bus test system show the effectiveness of the passive H<sub>∞</sub> controller. This work also suggests several directions for further research.
