Abstract

A first energy converter that can consume a first physical energy form of a first energy delivery network can be controlled to produce a second physical energy form of a second energy delivery network and inject the second physical energy form into the second energy delivery network. A second energy converter that can consume the second physical energy form of the second energy delivery system can be controlled to produce the first physical energy form of the first energy delivery network and inject the first physical energy form into the first energy deliver network. The controlling of the first energy converter and the controlling of the second energy converter can be coordinated. Related apparatus, systems, techniques and articles are also described.
