Abstract

In energy distribution networks, adequate investment planning is crucial not only for meeting the demands of established load points within the network but also for maintaining specific reliability standards. These two objectives, which involve meeting the demand economically and ensuring adequate service reliability levels, are highly dependent on the investments made in the electrical network. Therefore, this paper presents a mathematical model that incorporates both criteria to determine investment decisions in distribution networks. The developed model incorporates various types of investments, commonly found in long-term projects, such as investments in substations and circuits, which are evaluated over multiple investment periods. Moreover, a set of constraints is utilized to account for potential outage scenarios in the networks and assess the robustness of the investments against them; this includes considering circuit breakers as essential network structures for conducting network reconfigurations that minimize the number of users affected by outages. As a result, cost benefits were observed when incorporating decisions regarding the investment in circuit breakers, circuits, substations, and necessary upgrades due to the increase in network demand. The final study was conducted using a 14-node and a 27-node model.
