Method for Balancing Frequency Instability on an Electric Grid Using Networked Distributed Energy Storage Systems

Stem, Inc.

A patent family: one line of work, grouped by real continuity rather than by a technology label inferred from titles. 4 of these applications claim priority to application 61/700,840, filed Sep 13, 2012. A shared origin can cover several different claimed inventions, which is why members here may not share a title. In-force patents first, soonest term end first, then patent number. Expired patents follow, in the same order.
