Abstract
Described embodiments include a system and a method. A system includes an energy storage device configured to store and release energy. The system includes a waveform sensor configured to detect a second harmonic or higher frequency component deviation in a waveform of electric power supplied to the system by an electrical power grid. The system includes a bi-directional switched-mode converter coupled between the energy storage device and the electrical power grid. The switched-mode converter is configured to receive and convert electric power from the electrical power grid into energy stored in the energy storage device and to convert energy released from the energy storage device into electric power and discharge the converted electric power into the electrical power grid. The system includes a waveform correction manager configured to control the bi-directional switched-mode converter in a manner implementing a waveform deviation reduction strategy responsive to the detected deviation in the waveform.
