Sandia National Laboratories Introduces Grid Restoration Algorithm – PV Magazine International

From PV Magazine USA

A group of researchers at Sandia National Laboratories is studying ways to make the power grid more resilient to extreme weather storms and hackers. Their idea is to build a self-healing grid through various algorithms coded into grid relays. These detectors quickly restore power to critical infrastructure such as hospitals, grocery stores, assisted living facilities, and water treatment facilities before operators can make repairs or issue instructions to move forward. To do.

Sandia researchers envision these grid relays being incorporated into renewable energy supply microgrids and their local energy storage systems. The Sandia project focuses on connecting these small power islands around critical infrastructure so that they can automatically heal and share power to power as many users as possible. I am putting

Sandia researchers build on this resiliency by allowing microgrids to automate functions such as balancing energy production and consumption and reconfiguring when parts of the system fail. are planning to build. The algorithm should also prevent the microgrid from forming unintended loops in the circuit. Avoid the cost of relying on power inverters to provide the high-speed communications you need today while leveraging device-specific local measurements.

When it comes to automating the regulation of energy production and consumption, a Sandia-led team has developed an algorithm based on process inverters designed to provide power for use by microgrids during times of overload. But rather than stop regulating the mains voltage during a surcharge, the new system uses the drop in voltage to send a signal to a relay that cuts off power to non-essential customers, such as private homes.

Regarding reconstruction, the automated process is based on computer-aided design software. The proposed algorithm for three small-scale interconnected microgrids was able to identify problems such as downed power lines and damaged power plants and restore power to critical infrastructure.
