This paper describes the implementation of a distributed coordinating control system for power electronic converters in a shipboard distribution system that ensures system optimization dynamically. Multiple agents take part in the process to determine optimal power sharing for the converters. A distributable optimization method suitable for real-time coordination of converters is developed for deployment...
A thyristor-controlled supercapacitor energy storage (SES) system is proposed in this work to improve the transient stability of a synchronous generator located in a power network. To check how effective the proposed SES in augmenting the transient stability of the generator is, its performance is compared to that of a thyristor-controlled superconductive magnetic energy storage (SMES) system. Both...
The objective of this paper is to describe the implementation of an innovative agent-based architecture of controllers for stand-alone DC microgrids. The controllers regulate voltage to the required level and balance load flow in all converters. In addition, they maintain a deterministic time frame of a few 10's of milliseconds for a system with 10's of converters when there is no limitation in the...
The traditional method for the analysis of power quality (PQ) disturbances is fast Fourier transform (FFT) which suffers from spectral leakage phenomenon, and results in erroneous assessment in the presence of nonstationary PQ disturbances. Also, it cannot provide any time information as PQ indices are computed in the frequency domain only. Regarding the limitations of the FFT, in this paper Page...
The objective of this paper is to describe the implementation of an innovative agent based architecture of controllers for stand-alone shipboard DC microgrids. The controllers have to regulate voltage to the required level and balance load flow in all converters. In addition, they should maintain a deterministic time frame on the order of a few tens of milliseconds for a system with tens of converters...
The objective of this paper is to describe the implementation of a distributed and coordinated control system for converters in a shipboard distribution system that provides real-time system optimization. Multiple agents take part in the process to determine optimum power sharing for the converters. Optimal power sharing ensures minimum transmission and distribution loss while enforcing constraints...
