Dear Colleagues,

Today’s multienergy systems embody various energy vectors such as electricity, gas, and heat whose simultaneous operation represents a valuable source of demand-side flexibility. This flexibility provides an appropriate opportunity to address the concerns of the energy system outages that occur due to climate change, natural hazards, technical problems, and cyber-attacks. The outages cause several challenges and problems for industries, commercial and residential sectors, and public services. Therefore, flexibility and resiliency enhancement of today’s modern energy systems have recently received more attention by scientists and researchers. However, resilience enhancement needs huge investment costs if traditional methods are utilized. Therefore, new techniques and approaches, such as integration of multiple energy hubs to accommodate more renewable energies, island operation of energy hubs, and utilization of advanced technologies such as remote controlled switches, are necessary to increase the resiliency and flexibility of today’s energy systems. On the other hand, as today’s energy systems contain several downstream microenergy hubs, resilience improvement in local multi-energy hubs will be more beneficial than improvements at the national level. Smart control of microenergy hubs, in both islanded and grid-connected operation modes that contain different energy resources, thermal and electrical energy storage systems, electric vehicles, and demand response programs, will significantly increase the resilience of the modern energy systems. As a result, comprehensive studies are necessary to investigate the resiliency and flexibility of today’s modern energy systems.

The purpose of this Special Issue is to provide an opportunity for researchers to present new solutions to increase the resilience and flexibility of modern energy systems.  

Topics of interest include but are not limited to:

• Flexibility analysis of energy hubs and multiple energy hubs;
• Suppression of uncertainties and fluctuations in distributed renewable energies;
• Integration of multiple energy hubs to increase flexibility to accommodate more renewable energies;
• High-impact low-probability disruptive events;
• Advanced technologies for resilience enhancement;
• Operation and planning of multienergy hubs;
• Support decarburization by improvement of energy systems’ flexibility;
• Transportation electrification impact on resilience and flexibility;
• Local energy control and management strategies;
• System resilience in natural hazard conditions;
• Flexibility improvement by distribution network reconfiguration;
• Impact of high penetration of renewable energies on system resiliency;
• Post-restoration state analysis;
• Infrastructures recovery analysis;
• Demand response programs impact on system resiliency.
