Path-Based Distribution Feeder Reconfiguration for Optimization of Losses and Reliability

A hierarchical scheduling framework for resilience enhancement of decentralized renewable-based microgrids considering proactive actions and mobile units

“…Thereafter, the number of initial scenarios is reduced to 10 by the backward scenario reduction algorithm to reduce the computational burden, In Eq. (n1), the failure probability of each line is calculated according to the wind speed in that area [45]. Where, 0 ( , ) l i j…”

Effects of protection settings on optimal performance of reconfigurable smart distribution systems

“…In this method, the system operates under normal conditions concerning the initial state of the switches, and, if necessary, the topology of the ADN may be changed by reconfiguration of the tie switches. DSR is performed to improve the operational conditions of the system while maintaining the radial structure of the network to improve the performance of the protection system, limit short circuits, and avoid problems of ring networks [2,3]. The process of network reconfiguration is performed based on different goals in different periods such as hourly, daily, or seasonal.…”

“…For example, reconfiguration of the DN to reduce losses involves changing the topology of the DN so that not only power losses are reduced in the network, but also the radial structure of the network is maintained [4]. In addition, improvement of reliability indices can be considered as the main purpose of DSR as in [2] and [5].…”

“…Then, reconfiguration is performed according to objective function (2) in GAMS software, and a set of new structures are provided. It should be noted that the set is sorted from low to high based on the solution obtained for the objective, that is, system losses, such that the first solution has the least loss, the second has the best value bigger than the previous one, and so on until the main network structure is reached.…”
