DG-allocation based on reliability indices by means of Monte Carlo simulation and AHP

In this paper, a new method is proposed to determine the best locations of DG units mainly based on reliability indices. Sequential Monte Carlo simulation (sMCs) is utilized to calculate the reliability indices. One of the main advantages of using sMCs in bulk power system reliability analysis is the ability to provide reliability index probability distributions in addition to the expected values of the index. This method can also provide information about the uncertainty related to a definite level of system reliability. Then, the AHP method is used to select the best plans based on reliability indices and some other alternatives including power loss and voltage profile. The results show that the proposed method finds the optimal locations of DG units considering enhancement of criteria with and without uncertainties of reliability and load demand.
