Latest Patents

Greg Speckhart holds a patent for a system titled "Control of energy storage system inverter system in a microgrid application." This invention focuses on managing a supplemental energy source connected to a power grid. It employs a two-stage control strategy to effectively manage power transfers both in and out of the power grid and the energy storage system, such as a battery bank. The first stage utilizes a non-linear transfer function to control the output frequency of a DC-to-AC inverter, which helps limit the undesired effects of power transients occurring on the grid. The second stage implements a control strategy for transferring energy between the energy storage system and an internal DC link, based on the relationship between the voltage on the DC link and a reference voltage. This strategy includes features such as rapid charging, over-charging protection, and grid transient stabilization.
