Vermont Patent of the Month – April 2024

Dynapower Company LLC has been granted a patent for a new solution which revolutionizes power systems with its innovative approach to managing power generation, storage, and distribution. This breakthrough invention addresses the challenges faced by traditional power systems in efficiently utilizing renewable energy sources and maximizing power output.

At the heart of Dynapower’s invention lies a sophisticated power system designed to seamlessly connect power sources, energy storage units, and the grid. The system comprises a power inverter, an energy storage power converter, and a controller that orchestrates their operations.

One of the key features of this invention is its ability to capture excess power from the power source, such as a photovoltaic (PV) array, that cannot be immediately utilized or output to the grid. The controller autonomously detects if the power inverter is operating in a curtailed manner, meaning it’s unable to fully utilize the available power from the source. In such cases, the controller adjusts the charge command of the energy storage power converter to store the excess power in the energy storage unit, preventing wastage and enhancing overall system efficiency.

Dynapower’s power system prioritizes the utilization of power generated by the source, ensuring that stored energy is discharged only when necessary. By giving priority to power available from the source, the system optimizes power distribution and minimizes reliance on stored energy, thereby maximizing the utilization of renewable energy sources.

The controller is equipped with advanced emulation capabilities, allowing it to mimic the behavior of the power source, particularly in the case of PV arrays. Through sophisticated algorithms and look-up tables programmed with power-voltage characteristics, the controller effectively emulates the PV array’s power output. This emulation enables the system to adjust power commands of the energy storage power converter based on real-time conditions, ensuring optimal power generation and distribution.
