Electric power systems are physically some of the largest and most complex nonlinear systems in the world. Bifurcations are rather mundane phenomena in power systems. The pioneer work on the local bifurcation analysis of power systems can be dated back to the 1970’s and earlier. Within the last 20 years or so nonlinear dynamical theory has become a subject of great interest to researchers and e...

In this paper, we propose a novel approach for the data-driven characterization of power system dynamics. The developed method Extended Subspace Identification (ESI) is suitable systems with output measurements when all dynamics states are not observable. It particularly applicable dynamic identification using Phasor Measurement Units (PMUs) measurements. As in case systems, it often expensive ...

Nonlinear Dynamics is a very popular topic for researchers. The prior researchers already studied the nonlinear dynamics of current controlled DC-DC boost converter. The power factor corrected boost regulator is a circuit which is designed especially as input power factor can maintain unity. Firstly, we derive the state equations of this switching circuit. The circuit is numerically simulated b...

Differences of market force of coal and power industries caused this contradiction “market for coal, electricity for plans”. C&P (Coal and power) industries issues around dual pricing system seriously hampered the development of C&P industries. This paper used the System Dynamics method to analyze the composition, characteristics and ways to build of the C&P industries integrated energy system,...

Determination of the starter torque-speed diagram is a major task in the design or selection of a proper gas turbine starter. In this paper, the maximum power of the MGT-40 gas turbine starter was calculated based on the dynamics of the rotor, start-up logic, and compressor map. In a recent research, the pressure ratio was assumed as a linear function of the rotor speed and the required starter...

A Space Free-Flying Robot (SFFR) includes an actuated base equipped with one or more manipulators to perform on-orbit missions. Distinct from fixed-based manipulators, the spacecraft (base) of a SFFR responds to dynamic reaction forces due to manipulator motions. In order to control such a system, it is essential to consider the dynamic coupling between the manipulators and the base. Explicit d...
