Comparison of P&O and INC Methods in Maximum Power Point Tracker for PV Systems
In the context of renewable energy,the maximum power point tracker(MPPT)is often used to increase the solar power efficiency,taking into account the randomness and volatility of solar energy due to changes in temperature and photovoltaic.In all MPPT techniques,perturb & observe and incremental conductance are widely used in MPPT controllers,because of their simplicity and ease of operation.According to the internal structure of the photovoltaic cell and the output volt-ampere characteristic,this paper established the circuit model and establishes the dynamic simulation model in Matlab/Simulink with the preparation of the s function.The perturb & observe MPPT method and the incremental conductance MPPT method were analyzed and compared by the theoretical analysis and digital simulation.The simulation results have shown that the system with INC MPPT method has better dynamic performance and improves the output power of photovoltaic power generation.
