Power Point

An accurate method is proposed to track the maximum power point of a photovoltaic module. The method is based on the analytical value of the maximum power point voltage, determined from a mathematical model of the photovoltaic panel. The method has the advantage of accuracy without any oscillations, as with certain conventional methods. The algorithm has also the ability to track accurately the maximum power point under variable atmospheric conditions and load changes. Experimental results are presented to show the effectiveness of the method. The implementation of the method needs an online measurement of irradiance, panel temperature, and panel current and voltage.

Power Point

A relaxation method is proposed to determine the maximum power point tracking of a small to medium powered photovoltaic module, based on the non referenced MIT model, with analytical evaluation of the maximum power of the generated voltage. In implementing this algorithm, there is no need for continuous online measurements of temperature or irradiance, which are the most used variables used in the evaluation of the I-V relationship of PV cells. The method has the advantage of adequate accuracy without any oscillations, compared with certain conventional methods. The method can track accurately the maximum power point under changes in atmospheric conditions and load variations, by referring it with the MIT model.

AbstractBecause of nonlinear I-V curves of photovoltaic panels, a maximum power point tracking (MPPT) technique is necessary to absorb maximum power. In this article state-space averaging method is utilized to express behavior of boost chopper converter. To generate the best operating point (PV panel desired voltage), incremental conductance is used. A Robust feedback linearization controller is proposed to deliver the PV panel to maximum power point. The controller is robust to environment variations, load uncertainties and load voltage disturbances. Stability of proposed controller is proved based on Lyapunov theorem. A boost chopper is used between PV panel and load to realize proposed MPPT technique. Boost chopper parameters are designed properly to operate converter in continues conduction mode (CCM). To evaluate MPPT technique some simulations in irradiance variation, temperature variation, load variation and load voltage disturbance are presented and discussed.

This study investigated the output characteristics of photovoltaic module arrays with partial module shading. Accordingly, we presented a maximum power point tracking (MPPT) method that can effectively track the global optimum of multipeak curves. This method was based on particle swarm optimization (PSO). The concept of linear decreases in weighting was added to improve the tracking performance of the maximum power point tracker. Simulation results were used to verify that this method could successfully track maximum power points in the output characteristic curves of photovoltaic modules with multipeak values. The results also established that the performance of the modified PSO-based MPPT method was superior to that of conventional PSO methods.
