This paper presents a gravitational search algorithm (GSA) for solving the combined economic and emission dispatch (CEED) problem in power systems. Numerical results for the standard IEEE 30-bus six-generator test system have been presented to illustrate the performance and applicability of the proposed approach. The results obtained are compared to those reported in the recent literature. Thos...

This paper proposes a hybrid technique for secured optimal power flow coupled with enhancing voltage stability with FACTS device installation. The hybrid approach of Improved Gravitational Search algorithm (IGSA) and Firefly algorithm (FA) performance is analyzed by optimally placing TCSC controller. The algorithm is implemented in MATLAB working platform and the power flow security and voltage...

Targeting at the web page link features of Flash animation resource, Shark-search theme search algorithm is improved in the search width, link similarity judgment and selection of crawling links, and the search process of “search first and judge later” is employed. According to the experimental result, the improved Shark-Search algorithm may improve the efficiency of Flash theme webpage search,...

This paper proposes a methodology for an optimal operation of smart distribution network considering the reconfiguration, distributed generation (DG) units allocation and optimally placing shunt capacitors reactive power compensation. In this work, total losses minimization objective is considered. By optimizing objective, it can also results in reduction voltage deviation. The proposed problem...
