In this article, a novel method for synthesizing rectangular planar array through thinning and time‐modulation is proposed. A new differential evolution based approach that generates a rank based population is adopted to find out the optimum element off position for thinning and ontime duration to modulate the antenna elements in time domain. The proposed synthesis method defines a preservative boundary...
Congestion management (CM) is one of the severe problems in deregulated or liberalized electricity industry. In a liberalized electricity market, transmission lines are normally operated near its rated capacity and sometimes, this may cause congestion in the lines. This is because every market participants have the intention to maximize their profits. Failure of managing congestion properly may ultimately...
Optimal reactive power planning is one of the most challenging problems in power system operation. Different techniques including classical and modern heuristic methods have been utilized to address the problem successfully. It is observed that success of heuristic techniques largely depends on the selection of some user defined control parameters. Multiple runs are required to find the optimal values...
A novel approach using Differential Evolution (DE) is proposed for linear array failure correction. In presence of the failure of array elements, only the inter-element spacing's between the array elements are adjusted to regain the pattern closed to the original one. The proposed approach is a cost effective method as no additional attenuators or phase shifters are required. A fitness function has...
