A New System Risk Definition and System Risk Analysis Approach Based on Improved Risk Field
IEEE Transactions on Reliability, 2020Risk is an objective quantity applied to describe the degree of harm to a specific system of many activities and technologies. In order to manage risk successfully and ensure the normal operation of a system, an explicit system risk definition and a system risk analysis approach are essential.

Macromodeling as an approach to improve the analysis of electric power systems and their elements
2015 Modern Electric Power Systems (MEPS), 2015In the paper the problem of improving of electric power systems analysis using macromodels of their elements formed as state space equations using "black box" approach and expert analysis is considered. The process of the macromodel creation was illustrated on the example of transmission line.

Performance Analysis for Substation Automation Systems: A PICOM Approach and Improvement
2005 IEEE/PES Transmission & Distribution Conference & Exposition: Asia and Pacific, 2005The international standard IEC61850 defines all kinds of communication performance parameters among logic nodes in substations by PICOM, which is the foundation to evaluate the performance of substation automation systems. In the field of communication network protocol analysis, the Stochastic Petri Nets (SPN) is gradually applied widely.

Control systems are among the most important subsystems for their ability to undertake indispensable functions in safety-critical systems. Since many key components of such systems follow different performance degradation paths, therefore it is important to have an approach capable of correctly estimating the performance of control systems containing a

Journal of Vibration and Control, 2005
A design analysis approach is developed for improving the stability of dynamic systems subject to non-conservative forces. It combines genetic algorithms, sequential quadratic programming (SQP), and dynamic mode tracking (DMT). The proposed approach automatically optimizes the stability criterion and is applicable to rotor dynamics, wind turbine ...

An improved parallel maximum flow approach for vulnerability analysis of power system
2018 IEEE 3rd International Conference on Big Data Analysis (ICBDA), 2018Power system is becoming larger and more connectible, closely relating to human life and social development. However, with the increasing data volume and complexity, the danger of frequency collapse has always exist. To tackle this challenge, this paper proposes a parallel maximum flow based complex network approach to identify the critical lines ...

An improved approach to robust stability analysis and controller synthesis for LPV systems
International Journal of Robust and Nonlinear Control, 2010AbstractThis paper revisits the problem of robust stability analysis and synthesis for linear parameter varying (LPV) systems. By introducing two new slack variables, new conditions for the polyquadratic stability and for the affine quadratic stability of LPV systems are presented in terms of linear matrix inequalities.
