Title: Yuanzong Song: Innovator in Photovoltaic Simulation Technology
Introduction
Yuanzong Song is a prominent inventor based in Jinan, China. He has made significant contributions to the field of photovoltaic technology, particularly in the development of fast-response photovoltaic simulators. His innovative work addresses critical challenges in performance testing for high-performance grid-connected PV inverters.
Latest Patents
One of Yuanzong Song's notable patents is titled "Fast-response PV simulator based on improved deadbeat predictive current control." This invention focuses on a fast-response photovoltaic simulator that utilizes an improved deadbeat predictive current control (DPCC). The simulator significantly reduces the response time at the output compared to traditional PV modules. Current PV simulations often suffer from long response times, which do not meet the performance testing requirements of advanced grid-connected PV inverters. By studying the energy balance of the inductor during absorption and dissipation phases, Song established a DPCC model that enhances the current control law of the output inductor. An integral compensation mechanism is incorporated to eliminate steady-state errors in current tracking caused by nonlinear factors, such as time delays and mismatched parameters. This innovation allows for a transient response time of just 1.1 ms, which is considerably shorter than that of widely used PV simulations.
