“…To increase the emergency response capacities of power grid, [26] conducts an electricity-gas synergy planning with replacing certain power lines with natural gas transportation system. By exploiting the emergency support of gas/electricity, thermal storages, and building demand response, a multi-stage resilience scheduling with multi-level reserve is investigated in [27]; the critical loads in PDN can be strictly guaranteed. Reference [28] proposes a dynamic recovery strategy for integrated distribution networks, in which available resources including GTs and mobile storages are managed collaboratively to improve the amount of restored electricity loads.…”

“…As the coupling point of PDN and natural gas system, converter-based GTs in CESs can serve as controllable distributed generators to provide active and reactive support when electricity emergency takes place [47]. And the power factor of GT should be larger than the minimum allowed value, which can be represented in the form of (27). Furtherly, the converter capacity of GT is constrained in (28).…”

Owing to potential regulation capacities from flexible resources in energy coupling, storage, and consumption links, central energy stations (CESs) can provide additional support to power distribution network (PDN) in case of power disruption. However, existing research has not explicitly revealed the emergency response of PDN with leveraging multiple CESs. This paper proposes a decentralized self-healing strategy of PDN to minimize the entire load loss, in which multi-area CESs' potentials including thermal storage and building thermal inertia, as well as the flexible topology of PDN, are reasonably exploited for service recovery. For sake of privacy preservation, the co-optimization of PDN and CESs is realized in a decentralized manner using adaptive alternating direction method of multipliers (ADMM). Furtherly, bilateral risk management with conditional value-at-risk (CVaR) for PDN and risk constraints for CESs is integrated to deal with uncertainties from outage duration. Case studies are conducted on a modified IEEE 33-bus PDN with multiple CESs. Numerical results illustrate that the proposed strategy can fully utilize the potentials of multi-area CESs for coordinated load restoration. The effectiveness of the performance and behaviors' adaptation against random risks is also validated.

“…Thus, due to the significant need for natural gas-fired heating devices, natural gas loads are much more critical than electricity loads. However, as the workday gets started and the ambient temperature increases in (7)(8)(9)(10)(11)(12), the majority of critical loads belong to the PDN due to the importance of supplying commercial loads. In (13)(14)(15)(16)(17)(18) the portion of critical loads is high for both NGDN and PD N since there is a simultaneous need to supply electricity and natural gas for residential loads as residents are back home and commercial and industrial loads are still on.…”

This paper presents a multi‐objective restoration scheme for improving the resilience of integrated electricity and natural gas distribution systems against extreme weather events. The coupling constraints of electricity and gas networks are tackled properly using a linearized optimal power flow (OPF). Distributed generators, power‐to‐gas facility, rescheduling of generation/storage units, and microgrid formation are employed as operational resources/measures for restoring the integrated energy system after the event landfall. An adaptable directed multi‐commodity flow‐based microgrid formation is utilized, that is, the network configuration is dynamically changed in accordance with time‐variant load priority weights. The proposed method was successfully examined on an integrated electricity and natural gas distribution system comprised of the modified IEEE 33‐bus distribution network and a 14‐node natural gas distribution network. Numerical results showed that using microgrid formation increased the supplied critical load of integrated electricity and natural gas distribution system by about 16%. Moreover, due to making benefit of the power‐to‐gas unit, the supplied critical load increased by about 12.3%. respectively. While utilizing energy storage systems along with the power‐to‐gas unit facilitated the exchange of energy between the power distribution network and natural gas distribution network regarding time‐variant load priority weights, the supplied critical load increased by about 13%.

Coordinated fault recovery is essential for the resilience enhancement of integrated electric and heating systems (IEHS) following natural catastrophes as the linkage of the power distribution system (PDS) and district heating system becomes tighter. DHS reconfiguration is a viable method for service restoration because it could adjust the energy between energy sources and achieve uninterrupted energy supplies. In this paper, a collaborative service restoration model considering DHS reconfiguration is proposed to achieve better recovery after natural disasters. DHS reconfiguration could guarantee interrupted power supply in non-fault regions by shifting electric loads between power sources and accomplish optimal service restoration by adjusting the power output of combined heat and power units. Numerous case studies are undertaken to demonstrate the performance of coordinated reconfiguration on resilience enhancement and to confirm the efficacy of the proposed paradigm.
