Title: Innovations of Lars Johnson in Photovoltaic Technology
Introduction
Lars Johnson is a prominent inventor based in Concord, CA (US), known for his contributions to photovoltaic technology. With a total of 7 patents, he has made significant advancements in the field, particularly in maintaining the reactive power capability of photovoltaic power plants.
Latest Patents
One of Lars Johnson's latest patents is titled "Methods and systems for maintaining photovoltaic power plant reactive power capability." This invention discloses methods, systems, and computer-readable media for ensuring that photovoltaic power plants can maintain their reactive power capability through the manipulation of direct current (DC) voltage. The control system he developed includes a monitor input for receiving a signal indicative of the inverter system's input voltage and a control output for managing a voltage-clipping device in a solar panel system. This innovation allows for the reduction of solar output voltage by shorting out one or more photovoltaic solar cells when the input voltage exceeds a certain threshold.
Another significant patent is "Automatic voltage regulation for photovoltaic systems." This invention involves a photovoltaic system that includes solar cells and inverters designed to convert the direct current generated by the solar cells into alternating current. The system measures grid voltage at the point of interconnection with the power grid and generates a control signal based on this measurement. This control signal is crucial for adjusting the photovoltaic inverters to either generate or absorb reactive power in response to transient grid voltage changes.
