this paper presents a control strategy for fuel cell/energy storage power generation system during voltage sag conditions. the hybrid dc power sources are connected to grid using power electronic converters include dc-dc converter and grid connected voltage source inverter. the power from hybrid power sources is controlled during voltage sag by designing of control strategy for dc-dc converter....

My work in the past several years has dealt primarily with the study of the processes used in constructing varieties of problem solving behaviors. I have studied processes ranging from the propagation of constraints and non-chronological control schemes to belief revision, introspection, self-consciousness, and learning. While I consider many processes like these to be crucial ingredients of ef...

Randomized neural networks are immortalized in this AI Koan: In the days when Sussman was a novice, Minsky once came to him as he sat hacking at the PDP-6. “What are you doing?” asked Minsky. “I am training a randomly wired neural net to play tic-tac-toe,” Sussman replied. “Why is the net wired randomly?” asked Minsky. Sussman replied, “I do not want it to have any preconceptions of how to play...

this paper presents a novel method to calculate the reference source current and the referencecompensating current for shunt active power filters (sapfs). this method first calculates theamplitude and phase of the fundamental load current from a recursive algebraic approach blockbefore calculating the displacement power factor. next, the amplitude of the reference mains currentis computed with ...

The advantage of this method involves controlling the flow of current through all the connections – especially those used to measure the voltage. The measurement current flows through one set of connections, usually those that are farthest apart. If these connections are resistive (i.e., the connections are poor) there will be significant voltage drop across them. However, this voltage drop doe...

In this paper, an unmanned aerial vehicle (UAV) assisted cooperative communication system is studied, wherein a source transmits information to the destination through an energy harvesting decode-and-forward UAV. It is assumed that the UAV can freely move in between the source-destination pair to set up line of sight communications with the both nodes. Since the battery of the UAV may be limite...
