Abstract: 

In this paper, simultaneous allocation of multi-distributed generation, capacitor bank and sectionaliser are utilized to improve efficiency of the distribution network. After placement of devices based on constant load model, technical performance of the system is evaluated under loads sensitive to voltage and frequency. Wind turbine and photovoltaic are renewable distributed generation units that along other devices are been studied. The proposed multi-objective functions are composed of reduction active and reactive power loss, improvement of voltage index and reliability indices. A hybrid optimization algorithm using Combination of firefly algorithm and particle swarm optimization is proposed to solve the multi-objective optimal allocation problem. Moreover, a method based on fuzzy mechanism is employed to extract one of the Pareto-optimal solutions as the best compromise one. The proposed method is implemented on a IEEE 69-bus distribution network and also actual 100-bus distribution system in Khoy-Iran. The results approve the effectiveness of the proposed method with simultaneous placement of different devices for improving technical performance of distribution network.
