A power conversion and control system includes a power battery group and an energy battery group. The energy battery group is connected to a DC converter, the DC converter output being connected to a bus, and the power battery group is connected directly to the bus, so that operatively the voltage of the bus is variable. The bus may be connected to an inverter for output to a load, via a transformer. A difference in response time is provided between the inverter and the DC converter. The bus may be connected to the grid via a grid rectifier, and to the load via a load inverter. In an alternative, a power conversion and control system, includes a battery group, connected to the input of a load inverter, and to the input of a grid rectifier, wherein the system is adapted to provide frequency regulation power to the grid, to supply load power to a load via the load rectifier, and to provide charging power to maintain the state of charge of the battery, wherein signals indicative of the load power, frequency regulation power and charging power are summed by an adder in order to provide a control signal for the grid rectifier. |
