optimization of facts devices to reduce losses in transmission networks using hsa

Given the high costs of investment for transmission network development and the key role of transmission networks in restructured space, using facts devices is crucial. in this paper, the optimal placement of facts in transmission networks is investigated. in the proposed method, the objective function is defined for loss reduction a. average models available in references are used for modeling facts devices. the multi-objective harmony search algorithm is used for problem-solving. this algorithm has good speed in the convergence of non-linear problems. in the numerical studies section, the problem is solved in two different scenarios with the presence of different types of facts devices. results of numerical studies indicate that facts devices can have a considerable impact on loss reduction.
