“…In contrast with [8][9][10][11], in several research studies [12][13][14][15][16][17][18][19][20], many efforts have been made to preserve the original protection coordination between PDs after non-optimal adding the DGs. Unlike [8][9][10][11], these algorithms have been aimed to remove the need to apply new settings.…”

“…Inequalities (15) and (16) show the constraints of the bus voltage limit and the maximum allowable loading of the network lines, respectively. Inequalities presented in (17) and (18) are allowable range for the TMS value and the current setting of the PDs, respectively. Furthermore, inequality (19) represents the coordination constraint.…”

“…Also, each column of an individual from the population of the PDs contains a positive number that in addition to indicating the presence of the PD in that location, determines the value of the TMS for its overcurrent characteristic. Note that in determining the values of the TMS, the constraint presented in (17) must be taken into account.…”

“…A fitness value is then assigned to each individual from both populations, and each individual from the population of the DGs and its correspond individual from the population of the PDs with the minimum value of the cost function will be recorded. After that the new populations for the DGs and the PDs will be formed using the EA operators, considering the constraint of TMS that is presented in Equation (17). Before entering to the next iteration of the proposed algorithm, the current setting of the PDs based on the maximum line current in their direction of operation between all 96 h, considering the limit of the current setting presented in (18), should be determined.…”

“…In [16], the optimal allocation of the hybrid superconducting fault current limiters (SFCLs) has been performed to restore the protection coordination of the distribution system with the synchronous DGs. Moreover, DGs and the fault current limiters (FCLs) is optimally allocated to avoid false tripping of the PDs [17]. Optimal allocation of the DGs and the solid state fault current limiters (SSFCLs) have been performed in a distribution network which has been already provided with remote controllable switches (RCDs) [18].…”

Optimal coordination of the protection devices (PDs) is performed here simultaneous with optimal allocation of them and the DGs. The PDs are a set of directional overcurrent relays (DOCRs) and voltage relays, each with its own fast switch (FS). In previous optimal DG placement studies the coordination of the PDs has been considered as a constraint. So, it was not possible to optimal coordination of the PDs simultaneously. In the present study, the coordination between the PDs is considered in calculating the value of the energy not supplied (ENS) that is a part of an overall cost function. The cost function considered here includes cost of purchase, installation, and maintenance of the DGs and the PDs, cost of the energy losses, cost of the ENS, cost of the purchased energy from the main grid and the DGs, and the penalty cost for emitting environmental pollutants. Here, output of the renewable DGs and the network loads during the year, in a 96‐h model, has been considered as variable. To solve the desired optimization problem, an algorithm based on evolutionary algorithms such as genetic algorithm (GA) is proposed. Finally, various cases have been simulated by considering a standard 33‐bus radial network.

The integration of synchronous generators (SG) to the grid will present serious problems in some instances. The increase in fault current level is one of the most crucial issues, which causes miscoordination between directional over current relays (DOCRs), in addition to putting excessive pressure on the circuit breakers. This research uses the Fault Current Limiters (FCL) to restore coordination, without changing the settings of DOCRs, by reducing the level of fault current in the grid. The main goal of this research is to find the optimal size, location, and number of FCLs at the minimum cost and with the least operation time for the relays, using Jellyfish Search Optimisation (JSO) algorithm. This can be achieved through three different approaches. The first one is optimizing the location, number, and impedance size of the FCL by minimising a cost function. The second approach involves optimizing the backup relay operation time. A combination of the two previous approaches is used as the third approach. The outstanding feature of this research is that it considers the optimal location of DG and FCL while optimizing the operation times of DOCRs, which is a new framework.
