This paper studies the volt/var control strategy for smart distribution system by formulating and solving system optimization problems. In the study, solid state transformers (SST) are used for continuous var compensation, while voltage regulators (VR) are for voltage regulation. The objectives are to minimize total system power loss while maintaining voltages along the feeder within acceptable limits...
A supervisory strategy is proposed for improving the performance of an evolutionary-algorithm-based system-maintenance optimizer developed in our previous work for offshore power systems. The system-maintenance optimizer generates a set of initial maintenance plans, and exports them to an intelligent maintenance advisor connected to it for implementation. The proposed supervisory strategy uses a set...
In semiconductor manufacturing processes, mixed-products are usually fabricated on the same set of process tool with different recipes. Run-to-run controllers which based on the exponential weighted moving average (EWMA) statistic are probably the most frequently used in industry for the quality control of certain semiconductor manufacturing process steps. However, for mixed-product drifting process,...
A novel analytical approach is developed for determining the maximum traffic intensity for Low Earth Orbit Mobile Satellite Systems (LEO-MSS) under preset Quality of Service (QoS) constraints such as call blocking and dropping probabilities. The proposed methodology also enables the optimization of channel reservation for handovers so that the traffic intensity supported by LEO-MSS is maximized.
