Improved Immune Clonal Selection Algorithm for Photovoltaic Maximum Power Point Tracking Control
Abstract:
Maximum power point (MPPT) real-time tracking for photovoltaic
system is a kind of typical problem. This study is forward an Improved Clonal
Selection Algorithm (ICSA) through introducing cloning operator to solve real-time
MPPT. The algorithm which introducing reasonable clonal selection rate, clonal
proliferation rate, mutation rate can effectively improve the convergence speed
and avoid prematurity. The simulation model is established by using the equivalent
circuit of photovoltaic cell in MATLAB/SIMULINK. The ICSA is implemented using
m file under the MATLAB environment. Experimental results show that the proposed
algorithm has a remarkable quality of the global convergence reliability and
convergence velocity. This algorithm can effectively track the maximum power
point in real-time in case of variable temperature and light intensity.
