Conservation Voltage Reduction: Smart Grid Feeder Simulator

This simulator models a real radial distribution feeder — a substation feeding a line of houses — and solves it with the same backward-forward power-flow sweep utilities use in practice. Lower the substation voltage (the load-tap-changer setting) and watch every house's real power demand fall automatically, because most residential loads draw less power at lower voltage. A ZIP-model slider lets you control how much of the neighborhood's load behaves like constant impedance (full CVR benefit) versus constant power (none), while live readouts track the worst-case feeder-end voltage against the ANSI C84.1 Range A band, so you can push demand down without tripping a utility's under-voltage limit.
