Abstract

Wide-area measurement systems enable the wide-area damping controller (WADC) to use remote signals to enhance the small signal stability of large scale interconnected power systems. System operating condition variations and signal transmission time delays are the major factors to worsen the damping effect and even deteriorate the system stability. This article proposes a novel measurement-based adaptive wide-area damping control scheme using oscillation mode prediction and system identification techniques. These techniques adjust the parameters of WADC as well as the time delay compensation in an online environment. To achieve fast online implementation, an identified high order multi-input multi-output (MIMO) model is deformed into a low order single-input single-output (SISO) model according to the residue of MIMO model. The SISO model can accurately represent the power system dynamics in the form of a transfer function, capturing the dominant oscillatory behaviors in the frequency range of interest. Moreover, the WADC has been implemented on a hardware test-bed (HTB) by adding its output signal to the excitation system of a selected generator. In conclusion, the effectiveness of the proposed measurement-based adaptive WADC has been demonstrated in a two-area four-machine system on the HTB under various disturbance scenarios.

ARMAX-Based Transfer Function Model Identification Using Wide-Area Measurement for Adaptive and Coordinated Damping Control

Journal Article Liu, Hesen ; Zhu, Lin ; Pan, Zhuohong ; ... - IEEE Transactions on Smart Grid

One of the main drawbacks of the existing oscillation damping controllers that are designed based on offline dynamic models is adaptivity to the power system operating condition. With the increasing availability of wide-area measurements and the rapid development of system identification techniques, it is possible to identify a measurement-based transfer function model online that can be used to tune the oscillation damping controller. Such a model could capture all dominant oscillation modes for adaptive and coordinated oscillation damping control. our paper describes a comprehensive approach to identify a low-order transfer function model of a power system using a multi-input multi-outputmore »« less

Multivariable control of vapor compression systems

Conference He, X D ; Liu, S ; Asada, H H ; ...

This paper presents the results of a study of multi-input multi-output (MIMO) control of vapor compression cycles that have multiple actuators and sensors for regulating multiple outputs, e.g., superheat and evaporating temperature. The conventional single-input single-output (SISO) control was shown to have very limited performance. A low order lumped-parameter model was developed to describe the significant dynamics of vapor compression cycles. Dynamic modes were analyzed based on the low order model to provide physical insight of system dynamic behavior. To synthesize a MIMO control system, the Linear-Quadratic Gaussian (LQG) technique was applied to coordinate compressor speed and expansion valve openingmore »« less
A Gain Scheduling Wide-Area Damping Controller for the Efficient Integration of Photovoltaic Plant

Journal Article Zhou, Yichen ; Liu, Jiaomin ; Li, Yonggang ; ... - IEEE Transactions on Power Systems

With photovoltaic generation increasing, the wide-area oscillation has a vital influence on the long-distance power transmission of photovoltaic power. For an efficient integration of photovoltaic generation, a gain scheduling wide-area damping controller (WADC) is designed to guarantee system damping performance under a wide-area signal delay and a changing operating condition, which could be aggravated by the fluctuant and uncertain photovoltaic generation. A linear parameter-varying (LPV) model is proposed to represent all possible operating conditions within varying ranges of the photovoltaic generation and the load. Then, a tensor product (TP) model transformation is applied to transform the LPV model into amore »« less

Wide-Area Measurement-Based Modal Decoupling for Power System Oscillation Damping

Journal Article Fan, Rui ; Wang, Shaobu ; Huang, Renke ; ... - Electric Power Systems Research

Inter-area oscillation modes usually fall within the same frequency range of 0.1 to 1.0 Hz; thus, power oscillation damping (POD) control methods should avoid unnecessary excitation of weakly damped modes. This paper presents a decoupled control strategy to damp inter-area oscillations in the power grid. Pure oscillation mode signals are extracted from wide-area measurements and used as feedback input for POD actuators such as power system stabilizers or high-voltage direct current transmission. The decoupled control strategy is able to increase the damping of the concerned oscillation modes without deteriorating others. This proposed strategy could be implemented independently, or serve asmore »« less

Analysis of boiling-water nuclear-reactor-stability margin

Technical Report Balaram, J ; Shen, C N ; Lahey, Jr, R T ; ...

The phenomenon of nuclear-coupled density-wave oscillations in Boiling Water Nuclear Reactors (BWR) must be analyzed to demonstrate acceptable operational characteristics. Specifically, the stability margin required for acceptable system performance must be quantified. This is important not only from the design viewpoint but also from the requirement of establishing licensing acceptance criteria for a BWR. In this report the currently used licensing criterion based on the so called decay ratio of the system is analyzed. This criterion is based on a single-input single-output (SISO) analysis of the system and thus does not take into account the multi-input, multi-output (MIMO) nature ofmore »« less
