Abstract |
This paper proposes a maximum power tracking control algorithm based on the incremental conductance method with a variable step size coefficient that is not affected by the insolation of 50kW PV system. A PV module for consisting 50kW PV system is modeled as a single module considering the real-time calculation of RTBOX, and a control module is modeled to control MPPT and load balance of three-phase interleaved converter. HILS system consists of RTBOX, TMS320F28379D, and interface board. Through PLECS simulation and HILS, under the conditions of changes in insolation, performance of MPPT efficiency, tracking time to the maximum power point, and load balance of interleaved converter are verified. |
