“…Load restoration-based methods are another purpose of increasing resilience that has been used in [19]. MGs with DG are introduced as a viable solution in [20], [21] for local load survivability during contingencies due to their islanding schemes. In this regard, according to a hybrid AC/DC MG resilience enhancement, a resilience-driven approach is presented in emergency and normal operation mode.…”

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.

“…The utility grid guarantees the demand-supply balance in the MG in the grid-connected mode, and thus, the frequency can be maintained in an acceptable range; though, in the islanded mode, the MG may experience fast frequency deviations due to the intermittent nature of renewable sources, load variations and etc. The frequency of the islanded MG can be governed by (1) [7]:…”

A Life Cycle-Cost Analysis of Li-ion and Lead-Acid BESSs and Their Actively Hybridized ESSs With Supercapacitors for Islanded Microgrid Applications

et al. 2020

The combination of supercapacitors (SCs) with Li-ion Batteries (LIBs) and Lead-Acid Batteries (LABs) as hybrid ESSs (HESSs) have widely been proposed for Microgrid (MG) applications. The SCs of HESSs eliminate the stress of surge currents on LIBs and LABs, which increases their life cycles, and decreases their life cycle costs and hence decreases the HESSs operational costs. However, the active topology of HESS, which is the most commonly used configuration, requires an extra SC and an extra DC/DC converter in comparison to the Battery Energy Storage (BESS) topology, which increases the HESS capital cost. This paper tries to investigate that the hybridization of LABs and LIBs with SCs is economically effective or not for applications in islanded MG. In this regard, an energy management and frequency control (EMFC) scheme is proposed for the operation of MG in islanded mode. Using the simulations of the proposed EMFC scheme for islanded MG, the size of main components of LIB ESS (LIBESS), LAB ESS (LABESS), LIB-SC HESS (LISHESS) and LAB-SC HESS (LASHESS) are calculated. The numerical results show that for a 10-year period operation in islanded MG, the LISHESS and LASHESS impose less cost than LIBESS and LABESS. Also, the LISHESS is cheaper (almost 11%) than LASHESS.

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

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%.
