Title: An Optimized Input/Output-Constrained Control Design With Application to Microgrid Operation

Abstract

In this paper, a nonlinear control design is presented for systems whose input and output vectors are saturated. The proposed synthesis includes an optimal tracker as the seed controller and explicitly imposes all the relevant constraints on system input, on the rate of change in the input, and on system output by using the tools of barrier functions, input-output feedback linearization, comparison argument, Lyapunov argument, and a real-time constrained optimization. The proposed design is applied to microgrid operation with high penetration of renewable generation, where net load and variable generation must be balanced and the microgrid should be operated at an optimal or near-optimal performance level. Since traditional generation has a limited ramping rate, battery storage devices and demand responses become necessary to effectively deal with variability of renewable generation and to maintain frequency stability, but their capacities are also limited. Finally,it is shown that the proposed design is effective for coordinated control of traditional generation, storage and demand response so that the power system frequency is guaranteed to be within the required operational limits and that renewable curtailment is eliminated or minimized.

Distributed Real-Time Optimal Power Flow Control in Smart Grid

Journal Article Liu, Yun ; Qu, Zhihua ; Xin, Huanhai ; ... - IEEE Transactions on Power Systems

Conventionally, power system has a hierarchical control structure including primary, secondary, and tertiary controls. The drawbacks of this hierarchical scheme are manifest: 1) it lacks flexibility and scalability, which is against the trend toward an open-access power system; 2) load forecast as the basis of tertiary control could be inaccurate and infeasible, especially in microgrid for example; 3) as the penetration of renewable energy increases, the relatively long time-scales of secondary and tertiary controls cannot accommodate to more severe power fluctuation within the system. Here, to avoid these drawbacks, a distributed real-time optimal power flow control strategy is introduced. Withmore »« less

A Kernel-Based Predictive Model of EV Capacity for Distributed Voltage Control and Demand Response

Journal Article Valizadeh Haghi, Hamed ; Qu, Zhihua - IEEE Transactions on Smart Grid

Energy storage and reactive power supplied by electric vehicles (EVs) through vehicle-to-grid (V2G) operation can be coordinated to provide voltage support, thus reducing the need of grid reinforcement and active power curtailment. Optimization and control approaches for V2G-enabled reactive power control should be robust to variations and offer a certain level of optimality by combining real-time control with an hours-ahead scheduling scheme. This paper introduces an optimization and control framework that can be used for charging batteries and managing available storage while using the remaining capacity of the chargers to generate reactive power and cooperatively perform voltage control.

Distributed Link Removal Using Local Estimation of Network Topology

Journal Article Gusrialdi, Azwirman ; Qu, Zhihua ; Hirche, Sandra - IEEE Transactions on Network Science and Engineering

This paper considers the problem of network structure manipulation in the absence of information on the global network topology. In particular, the problem of removing some of links is investigated in order to slow or stop the spread of disease in a network while preserving its connectivity. Existing methods solve this combinatorial problem in a centralized manner and they require the global information of network structure. In this paper, we propose a distributed design algorithm to compute a suboptimal solution to this problem efficiently by mimicking gradient based method, namely by iteratively removing one or multiple links at a timemore »« less

Data-Driven Wide-Area Control Design of Power System Using the Passivity Shortage Framework

Journal Article Xu, Ying ; Qu, Zhihua ; Harvey, Roland ; ... - IEEE Transactions on Power Systems

A novel wide-area control design is presented to mitigate inter-area power frequency oscillations. A large-scale power system is decomposed into a network of passivity-short subsystems whose nonlinear interconnections have a state-dependent affine form, and by utilizing the passivity shortage framework, a two-level design procedure is developed. At the lower level, any generator control can be viewed as one that makes the generator passivity-short and L₂ stable, and the stability impact of the lower-level control on the overall system can be characterized in terms of two parameters. While the system is nonlinear, the impact parameters can be optimized by solving amore »« less

State-Constrained Grid-Forming Inverter Control for Robust Operation of AC Microgrids

Conference Xu, Ying ; Qu, Zhihua ; Qi, Junjian - 2020 European Control Conference (ECC)

In this paper, the problem of operating microgrids with only inverter-based energy resources is considered, and an integrated design of grid-forming inverter control is proposed. The proposed design has three components. The first is a nominal control designed to track the reference signals of voltage magnitude and frequency. The second as the primary control includes the nominal control as the seed and is a Lyapunov-based state-constrained control designed to ensure that the frequency, voltage, and power injections dynamically satisfy the operational constraints while incorporating intermittent renewables. The third is a subgradient-based cooperative control ensuring that the inverters cooperatively and collectivelymore »« less
