Smart Islanding and Power Backup in a Power Aggregation System for Distributed Electric Resources
First Claim
1. An apparatus, comprising:
- in a power aggregation system for distributed electric resources;
a line sensor associated with an electric resource, the line sensor to sense line power in a connection between the electric resource and a power distribution network;
wherein when a service of the power aggregation system signals the electric resource to generate power for the power distribution network and the line sensor senses no line power in the connection from the power distribution network, then a controller associated with the electric resource prevents the electric resource from electrifying the connection.

Abstract
Systems and methods are described for a power aggregation system. In one implementation, a service establishes individual Internet connections to numerous electric resources intermittently connected to the power grid, such as electric vehicles. The Internet connection may be made over the same wire that connects the resource to the power grid. The service optimizes power flows to suit the needs of each resource and each resource owner, while aggregating flows across numerous resources to suit the needs of the power grid. The service can bring vast numbers of electric vehicle batteries online as a new, dynamically aggregated power resource for the power grid. Electric vehicle owners can participate in an electricity trading economy regardless of where they plug into the power grid.
