In this work, the performance of a double-stage micro-inverter using the adaptive incremental conductance (AIC) algorithm for grid-connected photovoltaic (PV) modules is evaluated by means of a Simulink model. We observe the response of the micro-inverter under transients of solar irradiance and under static conditions. We show that Maximum Power Point Tracking (MPPT) and conversion efficiencies above...
This paper describes an approach to carry out performance analysis on systems which combine two major characteristics: real-time behaviour and parallel computational structure. It relies on a toolset composed of a monitoring system and a visualization tool. The steps to carry out performance analysis based on the toolset are clearly defined, and they are explained by means of a case study. First,...
A photovoltaic (PV) module simulator was developed based on an equivalent circuit with one-diode, taking into account variations of the solar irradiation and the temperature. The parameter estimation was carried out using the datasheet values provided by manufacturers and by solving a system of equations established from the physics of solar cells that constitute the photovoltaic module. The simulator...
In this work we study a new Improved Adaptive Incremental Conductance (IAIC) algorithm proposed originally by A. Morales-Acevedo for maximum power point tracking (MPPT). The maximum power point is searched by means of an adaptive correction of the DC-DC converter duty cycle which is determined by the sum of the incremental and the instantaneous conductance at a given time. The operating principle...
