“…In particular, the proposed IED-OLP formulation minimizes the AV20 index, i.e., a parameter establishing the economic penalty suffered by the energy supplier, as a result of the inefficiency caused to costumers due to a fault in the network. The proposed approach has been tested using a real radial network, constituted of 41 nodes, considering different customer distributions and varying the number of IEDs to be installed within the range (2)(3)(4)(5)(6)(7)(8).…”

“…They allow a fail f can be isolated by a couple (i, j) only if both nodes of the couple are active. Constraint (6) fixes the number of IEDs to be installed. Finally, constraints ( 7) and ( 8) fix the domain of the decision variables.…”

“…The IED-OLP-NLP formulation (3)-( 8) is a nonlinear programming formulation due to nonlinear constraints (6). However, it can be easily linearized by the introduction of couple activation variable for each couple of IEDs.…”

“…At the present, it is possible to equip the MV network with Intelligent Electronic Devices (IEDs), i.e., microprocessor-based devices capable of (i) receiving analog signal from sensors, (ii) controlling electrical equipment such as circuit breakers, capacitor bank switches, voltage regulators, (iii) exchanging messages with other IEDs or with Supervisory Control And Data Acquisition (SCADA) systems [4] according to a communication standard defined by IEC 61850 [5]. The use of IEDs allows the implementation of extremely fast and efficient methods for locating and isolating the fault [6]. An example is the localization of the fault through a logic selectivity approach [7,8]; it is based on the ability of the IEDs to communicate with each other and, on the basis of the exchanged messages, to decide autonomously to command the trip of a circuit breaker, so isolating only the faulty grid portion in a time interval compatible with the fault current tolerable by the line conductors [9].…”

In the paper, an analytical method for determining the optimal positioning of intelligent electronic devices in medium voltage grids is proposed. Intelligent electronic devices are automated devices able to communicate one with each other and command the circuit breaker in order to localize and isolate a line fault as fast as possible. However, the number of intelligent electronic devices to install has to be limited, due to the relevant installation costs and the reduction in the transmission bandwidth caused by the increased number of exchanged messages. So, the electrical distributor has to carefully detect the nodes of the grid where the intelligent electronic devices have to be installed. The authors propose a method based on integer linear programming, which, given the number of intelligent electronic devices to install, finds their optimal position, i.e., the one that minimizes the penalties associated with the power down experienced by customers. In order to highlight the offered advantages in terms of computational effort, the proposed approach has been assessed with a real medium voltage grid.
