| Summary: | This paper presents a comprehensive methodological framework to assess the contribution of distributed generation (DG) in smart buildings for improving the resilience of distribution power grids against extreme disasters. To achieve this, a new evaluation index, named energy supply reliability (ESR), is proposed to quantify the capability of DG in smart buildings to provide capacity support to the grid under extreme disasters, based on reliability analysis. The effects of multi-carrier energy demand and their interactions are explicitly considered in our index design. The mesh grid method and the Monte Carlo simulation are jointly used to calculate the power loss that presents after extreme disasters. A hybrid algorithm based on optimal scheduling technique is employed to examine the resilience of the distribution system with and without considering DG. The proposed framework is illustrated using a test case based on IEEE30 node systems, and the simulation results demonstrate that the appropriate utilization of DG in smart buildings can greatly improve the resilience and supply reliability of power grids against extreme disasters.
