TLDR
In this paper, a genetic algorithm is used to accelerate the performance of the algorithm in varied network conditions and results obtained are compared with the original method, which can give accurate solution faster to different loading patterns including ill conditioned one.Abstract:
Deregulation in power system has a positive impact on power system planning, reliability and profit at the cost of increase in complexity in the distribution system. Several methods have been proposed to study the unbalanced three-phase load flow solution for distribution systems. Approach[1] characterizes the network by using two matrices: the bus-injection to branch-current (BIBC) matrix and the branch-current to bus-voltage (BCBV) matrix. In this paper Genetic Algorithm is used to accelerate the performance of the algorithm in [1] during varied network conditions and results obtained are compared with the original method. Programs were developed in MATLAB for both the approaches and applied on the same test system. Test results showed that the proposed approach can give accurate solution faster to different loading patterns including ill conditioned one.read more
