Optimal simultaneous recloser and sectionalizer allocation using collective decision optimization algorithm(CDOA)

Abstract

One of the main important challenge of electrical distribution grid studies is the optimal allocation of protection devices having dominant impact on reliability indices, non-distributed energy, the rate of outages and, etc. In this paper the simultaneous optimal allocation of protective devices including recloser and sectionalizer is carried out by presenting the novel formulation by applying collective decision optimization algorithm (CDOA). Also, all the influencing factor such as permanent and transient short circuit faults and the customer's interruption duration are considered in problem definition. In addition, the defined objective function ensures the optimality of SAIFI, MAIFI, and SAIDI and the economic considerations. In order to synthesis the different parts of non-homogenous objective functions, the fuzzy theory is used. Ultimately, to evaluate the proposed method the study is carried out in 33 bus IEEE standard system an also a local 20 kv feeder in Semnan province.
