Physics Practical Magic

We don’t need to build a massive new power grid to go green; we just need better software to run the one we’ve already got.

The Takeaway

Current energy limits are based on static rules, but dynamic coordination of existing solar panels and heat pumps could increase the grid's capacity by 22 times. The bottleneck to a renewable future is digital coordination, not physical wires and poles.

From the abstract

We show that dynamic coordination of distributed energy resources (DERs) can increase the capacity of low- and medium-voltage grids, improve reliability and power quality, and reduce solar curtailment. We develop three approaches to compute hosting capacity on a representative distribution grid with realistic scenarios. A deterministic iterative method provides insight into how dynamic operation and DER interactions enhance capacity and affect power flows, demonstrating clear gains over static m
