This study introduces a mathematical trajectory based ‘Weibull Pareto sine–cosine optimisation (WPSCO)’ algorithm for the maximum power point tracking (MPPT) in the dynamics as well as in steady‐state conditions of a partially shaded (PS) solar photovoltaic (PV) system. This ‘WPSCO’ technique is used for quick and oscillation‐free tracking of the global best peak position in a very less number of steps, which is necessary to work in real‐time atmospheric conditions. The unique advantage of this algorithm for MPPT problem in PS condition is as it is free from common and generalised problem of the other evolutionary techniques such as longer convergence duration, a large number of search particles, steady‐state oscillation, unnecessary computational burden etc., which create power loss and oscillations in output. This hybrid algorithm is tested on different types of PV characteristics of the PS solar PV array by using MATLAB simulator and verified on a developed hardware of the solar PV system. Moreover, the tracking ability is compared with the state‐of‐the‐art methods. The satisfactory steady‐state and dynamic performances of the WPSCO algorithm under variable irradiance and temperature levels show the superiority over the state‐of‐the‐art control methods.
