The present disclosure provides systems and methods for controlling an electrical system. The electrical system includes a plurality of backup power sources, such as an electric vehicle battery, a photovoltaic system, and an energy storage system. The electrical system includes a service panel electrically coupled to a plurality of electrical loads. The electrical system includes an energy control system electrically coupled to the plurality of backup power sources, the service panel, and a utility grid. The energy control system converts to a plurality of settings based on the number of available backup power sources. The energy control system determines the availability of the backup power sources according to a predetermined protocol such that one or more backup power sources are prioritized over other backup power sources.

The energy management system and method provide for the control of electrical loads within a group. In one embodiment, a plurality of electrical loads are connected to an electrical grid and, upon detection of a predetermined condition, a user-defined sub-set of the electrical loads are disconnected from the electrical grid. The predetermined condition may be, for example, a blackout, thus when an interruption in power from the grid is detected by one or more sensors, the user-defined sub-set of the electrical loads is electrically disconnected from its electrical connection to the grid power. Following this disconnection, at least one of the electrical loads from the user-defined sub-set of the electrical loads is connected to an alternative source of power, such as a backup battery, a solar power system, a generator or the like.

A computer-implemented method for identifying behind-the-meter battery energy storage systems (BESS) in a distribution system includes measuring net power over a number of days via a meters at different locations in the distribution system. Using a time series of the measurement, a behind-the-meter BESS is detected by detecting flat intervals where the measured net power is substantially constant for a minimum continuous period, indicating BESS charge/discharge activity. If a BESS is detected, the time series data is used to detect first, second and third states that respective define net consumption, net generation and flat intervals indicating BESS charge/discharge activity. One or more eligible days are then determined that include a state change from the third state to the first state and a state change from the third state to the second. Intervals of BESS charge/discharge activity in the eligible days are extracted to evaluate a size of the detected BESS.

In order to ensure continued charging of electric vehicles when a charging station is not currently received an input power from an external power source, the systems and methods disclosed herein provide for operation of the charging station in a resilient operating mode in which an operating current is derived from a charge previously stored in a battery of the charging station. The operating current is produced by a resilient power subsystem within the charging station using the stored charge and is provided by the resilient power subsystem to one or more system components within the charging station in order to enable continued operation of the charging station, including enabling continuing vehicle charging during a time interval in which the charging station is not receiving input power from an external power source.
