“…Generally, in the DERs allocation problem and MG formation, reducing power losses and voltage stabilization are the main objective functions. In the present study, these functions, which are necessary from the point of view of economical operation of the network, are considered separately for both grid-connected and islanded modes [7,9,[39][40][41]. Equations ( 1) and ( 2) state the total Ohmic losses in MG and total voltage deviation in MG terminals, respectively, and should be minimized after DERs allocation.…”

“…In this regard, and to take advantage of these benefits, there are several excellent researches devoted to the subject of DERs placement in traditional distribution networks [7][8][9][10][11][12][13][14][15]. In this perspective, the use of optimization methods in DER placement has gained many attentions as through them various objective functions (OFs) and constraints can be considered simultaneously.…”

“…In this respect, the optimal siting and sizing of DER is obtained [9,[11][12][13]. For brevity, the research performed in this field can be categorized as: finding optimal placement of DERs for predetermined capacities [16,17], finding optimal DER capacities at specific locations, and simultaneous calculation of optimal locations and capacities of DERs [7,10,13,18].…”

Transformation of the distribution network, integrated with Distributed Energy Resources (DER), into a MicroGrid (MG) is an attractive approach in improving the reliability and resilience of the network. In this paper, by introducing the important and necessary aspects of the MG formation problem, an effective methodology for transformation of a distribution network into the MG is proposed. In the presented methodology, optimal allocation of DERs within MG is obtained by optimization of power losses and voltage stabilization along feeders. Moreover, the short-circuit constraints are also taken into account simultaneously while allocating DERs. The reason for the latter is that the integration of DERs alters the amplitude and direction of the short circuit current, which can cause the overall fault current to exceed the designed fault-level capability of the circuit breakers. This issue may put CBs at risk of failure and degrading MG resilience. In this regard, resilience-oriented evaluation of the MG formation, from the perspective of considering short circuit level and coordination of OCRs, is also performed. Another advantage of short circuit studies is devising complete and economic overcurrent-based protection plan for MG in both operating modes (grid-connected and islanded). It should be pointed out that adopting an appropriate control routine is a key element in the MG formation. Hence, a control strategy, based on Energy Storage System (ESS) utilization, is suggested in this paper. This feature, which is another contribution of the paper, will guarantee seamless transition to island mode and stable operation of the MG. The proposed formulation of the MG formation is solved using a modified multi-objective PSO and the Pareto-optimal set is obtained. However, since the optimal solutions are nondominated to each other, a Fuzzy Satisfaction Method (FSM) is utilized to find the optimal solution among the Pareto-set. Utilization of the proposed methodology leads to the successful transformation of the distribution network into a MG, which not only considers the load flow constraints but also preserves the optimal coordination of the protective relays and resilience of the MG. In addition, seamless transition and stable operation of the MG in island mode is achieved.

Increasing concern for environment has forced people to look for alternatives that are eco-friendly, thereby increasing the penetration of renewable resources. The opportunity to ameliorate economic status of consumers by generating revenue and by maximizing profit encourages consumers to look for substitute for conventional generation techniques. Operation cost minimization and export maximization are the two stages of profit maximization. By recognizing the optimal combination of DG resources such as photovoltaic (PV), wind energy resources, battery and microturbine and incorporation of demand response (DR) program with optimal scheduling of plug-in hybrid electric vehicle (PHEV), electricity import from the grid is reduced, thereby minimizing overall operation cost. The proposed DR program reduces imported electricity in peak hours by shifting non-emergency loads, which are classified here as controllable loads to off-peak hours, resulting in reduced import cost. Import cost and profit comparison for the considered systems under different levels of DR in the presence of multiple DG resources and EV for different scenarios are investigated to illustrate the effectiveness of the proposed DR. Maximized profit of microgrid operator is obtained by implementing the proposed method in the test systems. The results obtained are propitious.
