Estimation of photovoltaic module model’s parameters using an improved electromagnetic-like algorithm

This paper offers an electromagnetism-like (IEM) algorithm to estimate the five parameters of a single-diode PV module’s model. IEM uses local search and improves movement step to increase the convergence to optimal solutions. The key of improvement is performed by adding a nonlinear equation to adjust the length of the particle in each iteration. Moreover, the total force formula is simplified to speed up the exploration for an optimal...
