<span>An efficient procedure for defining the boundaries of microgrids in smart distribution systems during distributed generation expansion planning becomes an important consideration in constructing smart grids. A novel approach named "Modified Reverse Current Flow Method" is proposed in this paper to split a large radial distribution system into a required number of self-adequate microgrids. This cluster of microgrids will be capable of utilizing maximum power output of the distributed renewable energy generators and will act as highly reliable zones, during both islanded and grid-connected modes. This method is based on the trend reversal of the flow of current in the various parts of the circuit. This paper uses the practical machine operating curves of the distributed generators to calculate their reactive power output. For the considered distribution system, the proposed method is applied to find the optimal point of operation and the boundaries of microgrids. To bring out the superiority of this novel method, the improvement in reliability indices and economic savings of this method are compared with the results obtained using a similar method available in the literature. This method has several notable merits, namely, increased accuracy in the calculation of annual energy losses and the voltage profile. </span>

“…It is also a computationally in-depth problem whose dimension increases extremely with network size. Only a few research papers are available in the literature for optimization of CA and sizing together with NR [19][20][21][22][23][24][25][26][27][28][29][30].…”

“…Self-Adaptive Harmony Search Algorithm (SAHSA) as an optimization method feeder reconfiguration simultaneously with capacitor placement under five different scenarios, considering 100% and 120% loading conditions, to minimize the active power loss and to minimize the bus voltage deviation, has been reported in [29]. DSR (NR)/dual DSR-OCP (NR-CA)-based optimization for IEEE 33 and 69 bus test system were presented in [30]. To find the optimal solution for significant loss reduction and bus voltage profile enhancement, Modified Biogeography Based Optimization (MBBO), Binary Teaching Learning Based Optimization (BTLBO) and Discrete Dolphin Echolocation (DDE) algorithm have been adopted.…”

Capacitor Allocation (CA) and Network Reconfiguration (NR) are the traditional methods extensively applied by the researchers for power loss reduction and node voltage improvement in radial Distribution Network (DN) for the past four decades. In recent years, simultaneous optimization of CA and NR is considered to maximize the power loss reduction in a proficient manner in comparison to individual optimization of CA and NR. To solve the objective functions, this work proposes an application of Autonomous Group Particle Swarm Optimization (AGPSO) by optimal allocation and sizing of capacitors with and without NR, under four different cases, subject to satisfying operating constraints. In addition, to ascertain the impact of real power injection on further power loss reduction, this work considers placement and sizing of Distributed Generation (DG) units from single to three optimal nodes in capacitive compensated optimal DN. This proposed methodology is demonstrated using standard IEEE 33 and 69 bus test system and the results obtained by each test case have been compared with other optimization techniques. A significant amount of power loss gets minimized after optimal DG allocation in reactive power compensated optimal DN.

“…Distributed generators [15] as well as reconfiguration [16][17][18][19] are two solutions for reducing power loss of distribution. Both capacitor placement and reconfiguration were combined to reduce total loss [20]. In addition, static synchronous condenser (STATCOM) was also proposed to improve voltage profile of distribution systems [21].…”

Power radial distribution systems are increasingly more and more important in transmitting the electric energy from power plants to customers. However, total loss in lines are very high. This issue can be solved by allocating capacitor banks. Determining the suitable allocation and optimal sizing of capacitor banks needs an efficient approach. In this study, the diffusion and update techniques-based algorithm (DUTA) is proposed for such reason. The efficiency of DUTA is inspected on two distribution systems consisting of 15bus and 33-bus systems with different study cases. The solutions attained by DUTA are competed with recently published methods. As a consequence, the method is more effective than the other methods in terms of the quality of solution.
