Compared with a power system under centralized control, fully distributed control has stronger interdependence between its physical side and cyber side. Such is typical cyber-physical (CPS). The time delay problem one of the most critical issues in application for systems. First, information flow model established considering multiple sources delay, especially communication neighboring agents. ...

Computation and universality have been defined in the 1930’s. In the last five or so decades, it has been unveiled how common they are. The question about the frontier moved from proving the universality of dynamical systems to the complexity of universal machines. This is not only an intellectual challenge, but also important to find niches escaping tons of non decidability results or otherwis...

The stability analysis of islanded inverter-based microgrids (IBMGs) is increasingly an important and challenging topic due to the nonlinearity of IBMGs. In this paper, a new linear model for such microgrids as well as an iterative method to correct the linear model is proposed. Using the linear model makes it easy to analyze the eigenvalues and stability of IBMGs due to the fact that it derive...

This paper proposes a low voltage (±0.55V supply voltage) low power (44.65µW) high common mode rejection ratio (CMRR) differential amplifier (d.a.) with rail to rail input common mode range (ICMR), constant transconductance (gm) and enhanced frequency performance. Its high performance is obtained using a simple negative averaging method so that it cancels out the common mode input signals at th...

This paper modeled a doubly fed induction generator (DFIG) based offshore wind farm integrated through a voltage source converter –based high voltage direct current (VSC-HVDC) transmission system, which is collected with infinite bus for small signal stability analysis. The control system of HVDC system is considered for the stability analysis. The impact of the VSC control parameters on the ne...

This paper focuses on the small-signal stability of power system integrated with DFIG-based wind farm. The model of DFIG for small-signal stability analysis has built; the 3-generator 9-bus WECC test system is modified to investigate the impacts of large scale integration of wind power on power system small-signal stability. Different oscillatory modes are obtained with their eigenvalue, freque...
