PV MPPT Control System Based On ARM

Today, the traditional fossil energy is about to run out, the development of new energy is represent the general trend. Solar photovoltaic power generation because of cleanliness without pollution, Also can be considered to be inexhaustible energy in the foreseeable future. so, get the favour of people. The development of distributed photovoltaic power generation is a good way to make full use of solar energy, However, in the distributed photovoltaic power generation’ low budget, Use the maximum power point tracking (MPPT) technology to improve the efficiency of electricity generation is an important and difficult task.This paper first analyzes the principle of photovoltaic power generation, the mathematical model of photovoltaic cells, So after, analysis and compares several traditional classical The maximum power point tracking (MPPT) algorithm of PV, Mainly is the constant voltage method, perturbation and observation method and Incremental conductance method. After then, this paper combined with the characteristics of low budget in distributed photovoltaic power generation, Put forward a kind of new photovoltaic battery MPPT algorithm. This algorithm is simple, strong applicability, rarely restricted by the external environmental conditions, and the hardware requirements are not high.The simulation of the new algorithm shows that the new algorithm can effectively track the maximum power point of the photovoltaic cells. At the Last, this paper respectively from the software, hardware perspective on the photovoltaic maximum power point tracking (MPPT) control system design scheme based on ARM.
