Summary: | Distributed energy resources have been proposed as a promising solution to make households self-sufficient and increase power supply reliability. In this paper, we examine the reliability values of distributed solar+storage systems considering their possibility of survival during or rapid deployment after a rare weather event. To this end, we develop a theoretical basis and rule-of-thumb formulas for estimating the reliability value of a solar+storage system. The analytical results are used to calculate the optimal solar+storage capacities when reliability values are considered on top of the economic values and investment costs. Furthermore, to improve the accuracy of the proposed reliability value, we introduce a data-driven correction term based on realistic simulations using hourly electric load from 600 households in Austin, Texas, USA. Case studies demonstrate that 50% of households can achieve over 196.55 in annual reliability values by installing a solar+storage system with typical capacities. Combining our theoretical model with empirical data, we obtain an approach for fast yet accurate evaluation of the reliability value of solar+storage systems while avoiding the need for complex simulations. Therefore, our proposed theoretical analysis enables unsophisticated individual consumers to gauge the reliability benefits of distributed solar+storage systems amidst rare weather events when making an investment decision. |
