1 Jun 2022 | | Abstract: | The February 2021 Texas winter power outage has led to hundreds of deaths and
billions of dollars in economic losses, largely due to the generation failure
and record-breaking electric demand. In this paper, we study the scaling-up of
demand flexibility as a means to avoid load shedding during such an extreme
weather event. The three mechanisms considered are interruptible load,
residential load rationing, and incentive-based demand response. By simulating
on a synthetic but realistic large-scale Texas grid model along with demand
flexibility modeling and electricity outage data, we identify portfolios of
mixing mechanisms that exactly avoid outages, which a single mechanism may fail
due to decaying marginal effects. We also reveal a complementary relationship
between interruptible load and residential load rationing and find nonlinear
impacts of incentive-based demand response on the efficacy of other mechanisms. | | Source: | arXiv, 2206.00184 | | Services: | Forum | Review | PDF | Favorites | |
