N2 - Moving toward integrated distribution energy systems (IDESs) has many advantages, such as enhancing energy systems' overall efficiency and flexibility. The self-sufficiency of IDESs and the ability to face planned or unexpected equipment failure significantly impact their financial success and competitiveness. Therefore, it is essential to thoroughly study preparedness for contingency conditions in IDES planning. In this view, a two-stage risk-averse contingency planning for an integrated power and heat distribution system (IPHDS) is proposed in this paper. A long-term planning framework for IPHDS and shortterm operation constraints with N-1 contingency criterion is developed. Since DC distribution systems can be a future solution with higher efficiency and reliability than existing AC systems, the DC unipolar and bipolar configurations are compared to the AC counterpart to determine the optimal power distribution system (PDS) configuration. The simulation results present the concessions of incorporating contingency in the planning of IDESs from both economic and technical aspects and the DC-PDS impact on reliability enhancement. The bipolar DC configuration outperforms the unipolar DC configuration in terms of reliability while providing a 2.3% lower planning cost than the AC-PDS.
