Research on control strategy of two-stage single-phase photovoltaic grid-connected generation system controlled by MPPT
摘要
Abstract
In order to improve the maximum output power of PV system, the two stage single-phase grid connected PV system is studied. The Boost circuit of the system to put forward a new variable step incremental conductance method to achieve maximum power point tracking based on improved traditional incremental conductance method (MPPT), the inverter adopts P-Q control mode to realize the fast tracking of grid voltage, voltage outer loop electric double loop loop control, the inverter stable output of reactive power and active power. By setting up the MPPT model based on Boost circuit in Simulink, simulation of variable step size in maximum power tracking method and control strategy of grid connected inverter, the system not only can effectively improve the tracking speed and accuracy, fluctuations in the maximum power of the suppression system and can better meet the requirements of photovoltaic power generation, gridconnected inverter.关键词
