Numerical analysis of incremental conductance with cyclic measurement of the MPPT algorithm for PV power generation

摘要

This paper proposes the maximum power point tracking for the photovoltaic energy system using the novel incremental conductance (INC COND) with cyclic measurement of the tracking reference technique. Since the PV energy conversion system has low efficiency, and the power output of PV panel depends on the environment temperature, solar irradiation and climatic conditions. The proposed system infers the maximum charging power can be increased to a battery bank load through dc to dc buck-boost zeta converter. In the photovoltaic energy conversion system the absorbed solar light energy and cell temperature is directly transferred to the semiconductor but electricity conduction has irregular dissemination phenomenon in inhomogeneous physical. In the INC COND with cyclic measurement of the tracking reference can provide a dynamic numerical model to describe nonlinear characteristics. The proposed system change as dynamic variable is used to regulate the PV modules voltage toward the MPP. For low scale PV energy conversion system, the proposed method is validated by simulation with different operating environment conditions. Compared with the traditional methods, the results demonstrate the quick tracking time and practically in the MPPT of PV array.
