How to Prevent Blackouts by Packetizing the Power Grid

Cars That Think

That need for balance is true of electric power grids, too. Spiking demand for electric heat collided with supply problems created by frozen natural-gas equipment and below-average wind-power production. Packetized energy management (PEM) allows the power grid to flexibly handle a varying supply of renewable energy.
