A new study by MIT (Massachusetts Institute of Technology) engineers suggests that residential solar panels, electric vehicle (EV) chargers, smart thermostats, and other grid-edge devices could significantly enhance the resilience of power grids. The study, published in the Proceedings of the National Academy of Sciences, proposes a novel “local electricity market” to tap into the untapped energy potential of these decentralized resources.
Grid-edge devices—such as rooftop solar panels, residential batteries, EVs, and smart appliances—are located near consumers rather than centralized power plants. These devices can generate, store, or regulate electricity consumption. According to the MIT research team, these devices could be mobilized in response to cyber attacks or natural disasters, either by supplying power back into the grid or by adjusting their consumption.
The proposed framework, called EUREICA (Efficient, Ultra-REsilient, IoT-Coordinated Assets), envisions a future where grid-edge devices are Internet-of-Things (IoT)-enabled, allowing seamless communication within regional microgrids. The system would operate through an algorithm that identifies trustworthy devices capable of stabilizing the grid during disruptions. Participating homeowners would be compensated for their contributions through a local electricity market.
Lead author Vineet Nair and co-author Anu Annaswamy, a research scientist in MIT’s Department of Mechanical Engineering, emphasize that leveraging such devices can create a more resilient and adaptive power grid. The team tested their algorithm against various simulated grid failures, including cyber attacks and weather-related disruptions, and found that it successfully rebalanced the system in each case.
The study, which includes contributions from MIT, the Indian Institute of Technology, and the National Renewable Energy Laboratory, highlights the growing role of distributed energy resources in modern power systems. However, widespread adoption would require advancements in power inverters, policy changes, and consumer participation.
“This is just the first of many steps that need to happen for local electricity markets to become a reality,” Annaswamy said. “But we believe it’s a good start.”
