This paper show that it is possible to control a distributed generator coupled with storage to maintain grid flow constant at all times. Furthermore, it is possible to achieve a steady state operation with a periodic loading profile while enforcing active power limits and energy storage limits. An energy reserve for the storage is necessary to guarantee power to the loads during an islanding event. The control of the clustered pair, generator plus storage, is identical to microgrid source control, with some added constraints on the active powers. These constraints depend on the configuration that one chooses to adopt, either generator or storage performing the base loading function while the other performs the peak shaving function.
