A method for controlling an electrical consumer is provided. The electrical consumer is coupled to an electricity supply grid using a frequency converter. The electricity supply grid has a line voltage and is characterized by a nominal line voltage. The electricity supply grid is monitored for a grid fault in which the line voltage deviates from the nominal line voltage by at least a first differential voltage. When the grid fault occurs, the electrical consumer remains coupled to the electricity supply grid, and a power consumption of the electrical consumer is changed on the basis of the deviation of the line voltage from the nominal line voltage.

A system is provided herein. The system includes modules of an electric vehicle and a power receiver of the electric vehicle. The power receiver includes receiving coils and a controller. Each of the receiving coils directly and separately connects to a separate one of the modules. The controller monitors currents to and from each of the modules and modifies operation points of each of the modules by changing frequency or duty cycle to achieve a target current.

Systems and methods are provided for coordinating and providing bidirectional energy transfer events between electrified vehicles and households or other structures, such as for supporting household loads associated with the structures during power outage conditions. In some implementations, available energy may be rationed from the vehicle to the structure based on a power outage restoration estimate. Rather than supporting household loads with constant energy during power outage conditions, the disclosed systems/methods may provide strategic rationing of bidirectional energy transfer in order to extend appliance operation for the duration of power outage conditions.

A direct current (DC) power secondary distribution system is provided. The system comprises at least one first conversion unit and a one or more second conversion units. The first conversion unit receives alternating current (AC) electrical voltage from a distribution transformer of an AC power distribution system and converts the AC electrical voltage to DC electrical voltage output. The one or more second conversion units are connected downstream of the first conversion unit, and each second conversion unit converts the DC electrical voltage output from the first conversion unit to a respective AC electrical voltage output for a respective one or more loads. The one or more loads may be associated with a household.

An electric power management system is a system that performs an exchange of electric power with an electric power system of an electric power company that is a counterparty of the exchange of the electric power, and includes a plurality of the vehicles, each including a battery, and a server that manages an exchange of the electric power between the battery of each of the vehicles and the electric power system. The server manages the exchange of the electric power for each vehicle group in which the vehicles are bundled, and configures the vehicle group in advance by bundling the vehicles having the same or similar electric power supply and demand characteristics of the battery.
