Abstract

The current critical condition of fossil fuel crisis is rapidly increasing day to day and its harmful impact to the climate and environment is serious matter to take care. Thus, green energy or renewable energy is the only possible solution coming out of this context and solar energy is one of the most effective energy resources of these green energy system. In this manuscript we have discussed about a PV (photovoltaic) generation system with battery and capable of extracting maximum power output by using P&O type MPPT technique and it is working in isolated mode. As per the information given above, we have built a prototype of the system using a PV module capable of generating 1kW energy and the MPPT method has been implemented with the mean of using P&O technique. As the efficiency of the PV generation system is always a matter of concern the MPPT technique has been used to extract maximum power output from the PV array at any environmental condition. Here we used DC-DC converters as MPP trackers. A detailed model of the system first simulated using MATLAB/Simulink and later on the results have been validated to check effectiveness and suitability in the point of view of performance of the prototype has been added to this article. In each step of our designing of the prototype we tried to make it a cost-effective, simple and efficient model than the other existing models found in market.
基于MPPT的太阳能光伏系统DC-DC变换器的成本效益设计与控制
当前化石燃料危机的危急状况日益迅速加剧,其对气候和环境的有害影响是需要重视的严重问题。因此,在这种背景下,绿色能源或可再生能源是唯一可能的解决方案,而太阳能是这些绿色能源系统中最有效的能源之一。在本文中,我们讨论了一种具有电池的光伏发电系统,该系统能够通过P&O型MPPT技术提取最大功率输出,并在隔离模式下工作。根据上述信息,我们已经使用能够产生1kW能量的光伏模块构建了系统的原型,并使用P&O技术实现了MPPT方法。由于光伏发电系统的效率一直是人们关注的问题,因此采用了MPPT技术来提取光伏阵列在任何环境条件下的最大功率输出。这里我们使用DC-DC转换器作为MPP跟踪器。本文首先利用MATLAB/Simulink对系统进行了详细的仿真,并对仿真结果进行了验证,从样机性能的角度验证了系统的有效性和适用性。在我们设计原型的每一步中,我们都试图使它比市场上其他现有的模型更具成本效益,简单和高效。
