DEVICE ENERGY USE DETERMINATION
A device that runs on solar and battery power determines a current cycle energy budget by looking at a previous cycle or cycles energy accumulation and previous cycle or cycles unexpected expenses. The energy budget will then be the energy accumulation minus the unexpected expenses, normalized for cycle length. Based on the energy budget, an operating mode is chosen. The operating mode determines how often certain actions are taken. The device then runs for a cycle length based of the operating mode.
Power distribution control with asset assimilation and optimization
In a power control system a server maintains asset models that represent asset behaviour, each asset model being in real-time communication with its asset to dynamically inform the model of the status of the asset. A test is performed at the server by issuing a command to an asset requesting the asset to perform a function. Sensors at the asset measure physical parameters at the asset and report these to the server. The server determines whether the asset responded to the command and, if the asset responded, how it responded over time. The server establishes a model for the asset in terms of an energy capacitance and a time constant based on the measured response. An optimizer determines which assets are to participate in which service models. The server sends instructions to the selected assets to attempt to fulfill the services.
