On the application of PMU measurements to system stability analysis
… thesis proposes a method to analyze power system stability by utilizing PMU measurements. As the current power system is operated close to its limits, stability is of high concern for both operators and customers. The implementation of phasor measurement units across the power system allows for …

Computer Modeling and Simulation of Power Electronics Systems for Stability Analysis
… and to set conditions for safe operation. The stability analysis of this type of power systems has been approached using time domain simulations. There are three types of stability analysis that are studied: steady-state, small-signal analysis and large signal analysis. The steady-state …

Voltage-Offset Resistive Control for Photovoltaics
… the ideal VRC equilibrium are examined for stability. Small- and large-signal analyses show that one control equation for the boost converter is stable over the intended operation range—with some limitations based on component values. VRC is implemented using a digital controller on a boost …

Maltotetraose production using Pseudomonas stutzeri exo-alpha-amylase in a membrane recycle bioreactor
… purity were examined. The productivity at a steady state under optimized conditions was 0.99-1.11 g/L/hr depending on the kinds of starches. For the steady state conditions, a best fit model for prediction of yield was statistically developed using stepwise regression based on the data …

Offshore hybrid power plants with wind energy, photovoltaic and energy storage
… and firing pulses) is not recommended for steady-state stability studies, long-term simulations, or large electric power systems. For such studies, two averaged dynamic models are proposed in this thesis. Both models present the same control system as the switched dynamic model, except for …

Uncertainty Modeling of Wind Power Generation for Power System Planning and Stability Study
… make it difficult to maintain power system stability and reliability. In addition, the uncertainty and variability of wind power generation (WPG) forces power utilities to retain higher levels of spinning reserves (SRs) to maintain power balance in the system. While necessary to ensure grid …
