Aimed at the minimization of power flow response

a new approach with all optimization criterion and analytical iteration formula is proposed by guide weight method

which is introduced to model and solve the topology optimization problem. Several numerical examples are performed to investigate the effect of various frequencies of external load on the resulting optimal topology. The numerical results show that there are remarkable differences in the optimal topologies when the frequencies of the external load range from low

middle frequencies to high ones. The optimal topologies are analogous to one another for the external load with low frequencies

whereas they are more sensitive to the external load with middle and high frequencies. In addition the guide weight method provides highly efficient and accurate method to the topology optimization problems of power flow response with simple iteration formula

wide availability and fast convergence.
