Abstract
Aiming at two-stage photovoltaic power generation system,a new strategy of active power dispatch control was presented.The strategy could achieve quickly scheduling of two-stage photovoltaic inverter active power:when normal running,the boost chopper achieveed maximum power point tracking (MPPT)and the inverter had to be responsible for bus voltage control;when the active power dispatch instructions issued,inverter gave up bus voltage control and turned to control the output power decreased to the control value,at this time,the bus voltage would be rising,so the boost chopper circuit would turn to control bus voltage instead of MPPT control Two stages'control strategies did not interfere with each other.The control strategy was described in detail,then the simulation model and test platform were set up to verify the feasibility of this control strategy.关键词
