“…Some hardening strategies such as vegetation management and upgrading of network poles are applied to distribution system resilience enhancement. Scheduling of energy storage units [16], [17] and use of mobile emergency resources [18] are the solutions to increase resilience in the operation of distribution networks. Load restoration-based methods are another purpose of increasing resilience that has been used in [19].…”

Dealing with major power disruption during natural disasters is one of the most notable concerns in power systems. Due to renewable energy penetration and distributed generation resources in microgrids, they are considered as a potential solution to cope with severe events. Therefore, the application of microgrids in increasing and sustaining the distribution system resilience is considered. Furthermore, this purpose is pursued while maintaining the resilience of each DC microgrid connected to the distribution system, which is an essential and challenging issue. In the proposed method of this paper, a novel modeling strategy is formulated as a multi-period two-stage scenario-based stochastic mixed-integer linear programming (MPTSS-MILP) based on a multi-objective optimization problem (MOOP). In this framework, the operation associated with emergency and normal conditions, according to the influences of each situation on another one, is managed in multi-microgrids coordinately. In this regard, the technical constraints correlated to the operation of microgrids as well as the distribution system are satisfied simultaneously in specific to each condition which covers normal and critical operating under all uncertainty scenarios. Through introducing two evaluation criteria and also a resilience metric in microgrids and distribution systems, the efficiency of the proposed method is demonstrated. Meanwhile, innovative modeling is executed based on the subjective behavior of people affected by the disaster. Because the behavior of electricity consumers is one of the deciding factors in system management. The proposed scheme is implemented on a test system that involves a 34-bus distribution system with three distinct DC microgrids and its effectiveness is authenticated through various case studies.

“…Batteries are accepted as one of the most important and efficient ESSs, 4 which are attractive because they are economic, compact, and easy to deploy. In Reference 5, the battery ESS (BESS) is used for frequency control of an MG in islanded mode. The response time of BESSs is in order of milliseconds, in contrast to slow responding DG units such as DEGs, which makes them appropriate for PFC of MG 6 .…”

“…Moreover, the utilization of PV for PFC becomes efficient as it mostly operates at MPP, and the consumers' discomfort is also avoided as they do not experience long disturbances in residences' light intensity. Proposing to use PVs and SLEDLLs for handling PFC without FTSs in case of failure of SC, its converter or its controller, so that the MG is stabilized even when the SC is not operational. Previous studies like 5,7 have not considered the operational conditions during which the main ESS fails to handle the frequency control. In this paper, the reliable and safe operation of MG is ensured during these conditions using the proposed control scheme. Introducing a novel scheme for fast controlling of TCLs to participate in PFC.…”

Summary The supercapacitors (SCs) are suitable for short‐term fast power regulations, while the batteries are suitable for long‐term slow energy management of microgrid (MG). As SCs and batteries complement each other's deficiencies, the SC‐battery hybrid energy storage systems (SBHESS) have been commonly used for mixed applications of fast transient and slow long‐term power regulations. The SC reduces the stress of fast power variations on the battery, which prolongs its lifetime. However, it increases the cost of the energy storage in comparison to the case that battery is just used. Therefore, the drawback of SBHESS is its increased cost. The sizes of SC and its converter, which directly determine their costs, should be enough to handle primary frequency control (PFC) in the worst cases of shortage and surplus power generation that the MG ever experiences. In this paper, the potentials of Photovoltaic (PV) systems, smart LED lighting loads (SLEDLLs), and thermostatically controlled loads (TCLs) in PFC is used to decrease the participation share of SC in the PFC and hence decrease the sizes and costs of SC, and its converter. The simulation results show that with the coordination of SBHESS, SLEDLLs, PVs, and TCLs, the required sizes of SC and its converter are decreased by 64% and 50%, respectively. Also, for a 10‐year period operation, the total cost of SC and its converter is decreased by 51.5%.

“…As far as the MG is connected to the main grid, the demand-supply balance is ensured in the MG, and maintains the frequency of the MG within a tight range. However, the MG may suffer from the load-generation unbalance during the islanded operation [1]. An MG with low inertia can experience large frequency deviations [2].…”

The supercapacitor-battery hybrid energy storage system (SBHESS) has been commonly used to reduce the stress of fast power variations on the battery, and hence, prolong its lifetime. However, the utilization of the supercapacitor (SC) significantly increases the cost of energy storage system. Considering the potentials of the photovoltaic systems, the smart LED lighting loads and the thermostatically controlled loads in primary frequency control (PFC), three novel PFC schemes are proposed for each of them. They are enabled to cooperatively participate in the PFC of islanded MG alongside the SBHESS. Their cooperative application alongside the SBHESS decreases the participation share of the SC in the PFC and hence, reduces the size and the cost of the SC and its converter which consequently decreases the SBHESS cost. In this regard, the genetic algorithm is employed to tune the controller coefficients of the PFC schemes and the distributed generators to limit and minimize frequency deviations within an acceptable range, and also minimize the size of SC and its converter. The results show that the proposed cooperative application considerably decreases the size and the cost of the SC and its converter. This is while the SBHESS battery life is still extended the same as the case in which the SBHESS is used alone. As the frequency control results are similar with and without the proposed cooperative application and the imposed cost is much higher in the latter case, the proposed cooperative application increases the cost-effectiveness of the SBHESS.
