分布式能源可以增强社区对自然灾害后停电的抵御能力。本文提出了一种量化屋顶太阳能系统为居民区提供的弹性价值的方法。房屋按地理位置分组，以模拟当一场灾难使电网瘫痪并损坏一些房屋时共享能源的效果。历史能源消耗和太阳辐照度数据用于估计每个集群能够满足其自身能源需求的可能性，给定屋顶太阳能采用的定义水平和模式。作为一个案例研究，该方法应用于加利福尼亚州圣卡洛斯的单户住宅，该房屋遭受了代表1906年旧金山地震的灾难场景。该案例研究表明，较高的屋顶太阳能采用水平如何增加一年中不同季节的震后电力可及性。它还表明，政策干预可以确保太阳能在地理上的采用更加均匀，从而提高恢复力。最后，本文评估了这种干预的效果和成本，发现适度的补贴可以在整个社区的恢复能力方面产生显着差异。
Distributed energy resources can enhance community resilience to power outages in the aftermath of natural disasters. This article presents a method to quantify the resilience value that rooftop solar systems can provide to residential neighborhoods. Homes are grouped into geographical clusters to simulate the effect of sharing energy when a disaster disables the electric grid and damages some of the homes. Historical energy consumption and solar irradiance data are used to estimate the likelihood that each cluster could meet its own energy needs, given a defined level and pattern of rooftop solar adoption. As a case study, the method is applied to single-family homes in San Carlos, California, subjected to a disaster scenario representing the 1906 San Francisco earthquake. The case study shows how higher rooftop solar adoption levels increase postearthquake power accessibility during different seasons of the year. It also demonstrates that policy intervention can ensure more geographically uniform solar adoption and, therefore, more even resilience. Finally, the article evaluates the effect and cost of such an intervention, finding that a modest subsidy can make a notable difference in evening out resilience across a community.
