Title: Yeqin Wang: Innovator in Photovoltaic Systems
Introduction
Yeqin Wang is a prominent inventor based in Lubbock, TX (US), known for his contributions to the field of photovoltaic systems. He has been awarded 2 patents that showcase his innovative approaches to energy management and control systems.
Latest Patents
One of his latest patents is titled "Seamless mode change between grid-connected mode and islanded mode for PV systems." This invention presents a unified control scheme that enables a seamless transition between grid-connected and islanded modes for photovoltaic systems. The system comprises two decoupled control units: a DC-DC converter control unit and a DC-AC converter control unit. The DC-bus voltage is managed through the DC-DC converter, which provides a stable DC source to the DC-AC converter. The seamless mode change is facilitated in the DC-AC converter control module using three digital switches, ensuring continuity of control signals across all units.
Another significant patent is "UDE-based robust droop control for parallel inverter operation." This invention introduces a control system that incorporates a UDE (Uncertainty and Disturbance Estimator)-based controller to achieve proportional load sharing among parallel-operated inverters. The UDE-based controller effectively regulates reactive power based on load voltage, while the conventional droop method manages real power to generate the phase of the control voltage. This innovative approach allows for the estimation and compensation of model uncertainties and system disturbances, ensuring accurate load sharing.
