| Abstract_FL | According to the problem of lower efficiency of PV array in shadow or component fault conditions, based on the adaptive particle swarm optimization algorithm (SA-PSO), this paper proposes a control strategy which combines maximum power point tracking and switch matrix, and gives restart and termination conditions of the algorithm to avoid the frequent use of switch and power swing when the system tends toward stability. First, the restart condition of the algorithm is judged, if it is an unnatural restart, it needs to recognize optimal module array connection scheme under the abnormal situation by using optimization algorithm. And then it uses controllable switch matrix array to real-timely optimize photovoltaic array configuration mode. Finally, simulation results verify that the proposed method can quickly and accurately track the global optimum MPP in the shade or fault conditions, and effectively improve the output power of photovoltaic array. |
