In one embodiment, an energy manager determines respective energy profiles of one or more local end-devices for which the energy manager is responsible. Through communication between a power grid controller and the energy manager, one or more aspects of power grid operations may be controlled based on the communicating and the respective energy profiles. For example, in one embodiment, upon receiving a global demand response (DR) request, the energy manager determines respective specific DR control for the one or more local end-devices based on the received DR request and the respective energy profiles, and transmits the respective specific DR control to the one or more local end-devices, accordingly. In another embodiment, power grid operations may be stabilized based on the respective energy profiles.
