Abstract
A fast-response photovoltaic (PV) simulator based on an improved deadbeat predictive current control (DPCC). Compared to actual PV modules, there is a response time at the output of the PV simulation. Currently widely used PV simulation have a long response time, which cannot meet the performance testing requirements of high-performance grid-connected PV inverters. Based on the energy balance of the inductor during the absorption and dissipation phases, the current control law of the output inductor in the PV simulation was studied in a single switching period, thereby establishing the required DPCC model. An integral compensation eliminates the steady-state error in current tracking caused by nonlinear factors such as time delay and mismatched parameters, enabling its wide application in engineering. For the proposed PV simulator, the transient response time can be reduced to 1.1 ms and significantly shorter than widely used PV simulation.
