Abstract
The disclosed system includes a metering device for monitoring electrical power grid conditions, a controller for determining if the metering device is detecting a condition on an electrical grid that is indicative of a delayed voltage recovery event, and a communication device for communicating with one or more remotely located bi-directional power source modules connected to the electrical power grid, wherein the controller is programmed to send a notification via the communication device to the one or more remotely located bi-directional power source modules if the controller detects a condition indicative of delayed voltage recovery event. In some embodiments, the metering device includes a grid metering device. In some embodiments, the metering device measures power factor, and a change in the voltage and ratio of VARs to Watts.
