Resiliency constraint proactive scheduling against hurricane in multiple energy carrier microgrid

Hurricane, as one of the most frequent natural events, causes damage to the infrastructure of the upstream networks of multiple energy carrier microgrids (MECMs). Thus, the supply continuity of critical loads is threatened due to sudden islanding of MECMs from the upstream networks. Therefore, providing a framework to enhance the resilience of MECMs against this threat is necessary. In response to this issue, this paper presents a proactive optimal operation scheduling approach that is constrained to the feasible islanding of MECM from the upstream networks as well as the continuous suppling of the critical loads until the return of the upstream networks. Proposed resiliency constraint proactive scheduling is formulated as a mixed integer linear programming (MILP) that considers the interdependence between all three electric, gas and heat networks. The demand responsibility of all three electric, thermal and gas loads is used to consider the satisfaction of the consumer beside economic and resilient operation. Furthermore, both normal operation and contingency‐based uncertainties are taken into account and captured using a robust optimization method. Then in order to evaluate the resilience of the MECM, feasible islanding and preparedness indices are proposed. Finally, the effectiveness of proposed approach is illustrated using an MECM test.
