Several transient stability software packages are widely used for power grid planning and operations. Prior research and software documentations have shown that packages can vary in the implementations of dynamic models, and hence could potentially yield different results for the same system simulation. This paper presents a systematic methodology to determine the sources of the discrepancies seen...
In this paper, a digital repetitive control strategy is proposed to achieve zero tracking error for Power Electronic Load Simulator (PELS). The proposed control scheme is of ldquoplug-inrdquo structure: a plug-in digital repetitive controller plus a conventional controller (e.g., P or PD controller). The design of the plug-in repetitive learning controller is systematically developed. The stability...
Presence of distributed generation (DG) can represent a significant impact on the distribution networks, such as system reliability, power flow, relay protection, voltage profile and stability. It brings great challenge to the traditional distribution networks. Voltage profile is of great importance to consumers because itpsilas a basic demand for electrical equipments running near the rated voltage...
Distributed generations have become an important part of electrical generation in many countries and its importance is continuing to increase. The exact models of distributed generations are important for load flow program, stability analyses and other applies in distribution systems. But the absence of basic data results in the difficulty of modeling for distributed generator. Based on the knowledge...
In this work, we present modeling and experimental data for controlling the dynamic pull-in and the escape-from-potential-well phenomena for a capacitive MEMS device using phase control technique. The device is actuated with a DC voltage superimposed to an AC harmonic voltage. An inevitable escape band of frequencies, where a MEMS resonator is forced to pull-in, is simulated theoretically and found...
A speed controller based on MRAS method is presented to improve the speed control performance of the PMSM servo system. The output of system follows the output of reference model and maintains good speed performance when the motor parameters and load varies, which makes the system more robustness and adaptability. Experimental results demonstrate that compared with conventional PID control, the MRAS...
The supply function equilibrium model has been used widely to study strategic behavior and market power in electricity markets. However, theoretically there exists a continuum of supply function equilibria, which limits the predictive value of this model. We refine the supply function equilibria by a stability analysis. The local behavior of supply function equilibrium under small perturbations in...
With technology scaling, vulnerability to soft errors in random logic is increasing. There is a need for on-line error detection and protection for logic gates even at sea level. The error checker is the key element for an on-line detection mechanism. We compare three different checkers for error detection from the point of view of area, power and false error detection rates. We find that the double...
This paper introduces a novel current sense amplifier (CSA) in sub-32nm fully depleted (FD) double-gate (DG) silicon-on-insulator (SOI) technology with planar independent self-aligned gates. A new architecture is proposed which takes advantage of the back gate in order to improve circuit properties. Compared to the reference circuit, the new architecture proves to be faster (21% sensing delay decrease),...
A modification of the basic PI controller structure capable of improving performance with little or no loss of stability characteristics is presented. Several test cases are examined for both set point changes and load rejection and the results compared to those obtained with a standard PI algorithm.
