“…Some additional previous studies have focused on the use of multi-energy systems at urban scales [27,28], and the most relevant research efforts are related to the design and evaluation of DER (Distributed Energy Resources) energy systems as available systems to enhance whole-grid resilience [29][30][31][32][33][34][35][36]. Control strategies [37][38][39][40][41][42][43][44] and control systems have been deeply analyzed, and extensive research on the optimization and multi-objective optimization of control strategies has been applied to microgrids [45][46][47][48][49][50][51][52][53][54]. Still, there need to be particular case studies of the influence of load profiles, tariff structures, and available solar radiation impacts on energy costs and carbon emissions in buildings with critical loads and of the impacts on resilience.…”

This research aims to optimize and compare the annual costs of energy services in buildings with critical loads and analyze case studies for hospitals and higher education institutions in the United States. Besides electricity and natural gas costs, the study considers all the infrastructure costs of capital amortization and maintenance. In addition, it studies energy resilience improvement due to distributed generation, including solar photovoltaic, solar thermal, internal combustion engine, and fuel cell sources. The optimization considers the electrical consumption, the heating and cooling demands, and the operational strategy of the energy storage systems. To simulate real scenarios, energy tariffs were modeled and considered, and final optimization results were produced. Some of the microgrid load was considered critical to model resilience benefits. The results show that if favorable energy tariffs are applied, the benefits of increasing energy resilience represent a novel market with high potential in facilities with significant critical loads. This methodology can be used in similar scenarios, adapting each particular load profile and critical load to provide a combined optimal solution regarding resilience and economic benefits.

Electrical microgrids (EMGs) are positioned to play an important role in the future distribution grid as technology advances and distributed energy resources (DERs) emerge. In the event of major natural disasters, the functioning capabilities of active distribution systems (DS) face ongoing problems. To assess the resilience of a distribution system, a thorough methodology must be established. This study proposes a methodology that demonstrates how the use of EMGs and DERs, in conjunction with line hardening, can improve resilience in extreme operating situations. The framework examines four separate scenarios, each with its own set of restoration procedures and critical loads. A combination of battery electric vehicles (BEVs), solar photovoltaic distributed generation (SPV-DG), battery energy storage systems (BESS), and distribution static compensators (DSTATCOMs) is being integrated into practical Indian distribution systems consisting of 28 and 52 buses to improve resilience. The goal is to improve the newly specified resilience indices and restore all of the loads that have been affected by the faults. The bald eagle search algorithm (BESA) is used to identify the appropriate allocation of SPV-DG and solve the objective function within the system. The results of our tests show that our proposed technique has the capacity to enhancement the resilience and successfully restore all damaged loads in a distribution system.

“…Nonetheless, the DC microgrid has several advantages [2][3][4][5] over the AC microgrid such as low cost, low complexity, high reliability, energy efficient, etc. Several configurations of the power electronic converters are described in [6][7][8] for an application of the DC microgrid. This DC microgrid network [6][7][8] is susceptible to cyber-attacks as the centralized and hierarchical controllers require a communication channel for its reliable operation.…”

This DC microgrid network [6][7][8] is susceptible to cyber-attacks as the centralized and hierarchical controllers require a communication channel for its reliable operation. The attack model in a cyber-physical system [9,10] is divided into three categories: disclosure attacks, deception attacks, and disruption attacks.…”
