| Naval ship power system is an autonomous, mobile and in some instances warship. So, optimizing design selection as well as the operation at different system conditions is required. In the work presented in this dissertation, an integrated framework for damage control for the integrated shipboard power system with cost benefit analysis is presented. The scheme consists of four main modules. The first module proposes an optimal architecture selection tool using analytical hierarchy processing. The second module proposes a new power flow tool that deals with the integrated shipboard power system that contains power electronic components and both AC and DC loads. As the system is subject to different sources of faults and enemy attacks, the third module of the scheme deals with evaluating the system performance indices in terms of system reliability, voltage stability, and static security assessment under different system operating conditions, this module is used to filter the contingencies based on pre-defined limits of indices. The last module deals with the control coordination problem. This problem has been dealt with as a multi-level optimization problem in which the site, size and type of the control are to be optimized. Cost benefit analysis is used as a financial judgment for the selection of the control type. The proposed scheme is tested on the benchmark naval ship power system with DC zonal distribution system and the results show that the proposed scheme is very efficient not only in selecting optimal architecture but also in assessing different control options economically. |
