It has been decades since automation was introduced to electrical networks, yet it has not found its right place in the distribution level. One of the main obstacles in the path of automating electricity distribution system is the amount of investments needed for its implementation. This study presents a novel idea for distribution automation (DA) implementation planning, in which the sequence and timings of installing automatic switches are optimised, to exploit periodical savings and to minimise the total externally financed investment. The planning optimisation problem is formulated and solved in a mixed‐integer non‐linear form. The monetary value of periodical savings depends on several factors including network size, type of the distribution system operator, local regulations etc. To include all these factors, a scenario‐based method is developed to test the proposed method. Finally, the method proposed is tested on parts of the network covered by Tehran Vicinity Electricity Distribution Company as well as bus number four of Roy Billinton test system. The results show that a considerable part of investments needed for DA can be financed through exploiting periodical savings of DA, in a reasonable time, thus a partial self‐sufficiency can be reached for DA project financing.
