Abstract

Solar photovoltaic systems are an increasing option for electricity production, since they produce electrical energy from a clean renewable energy resource, and over the years, as a result of the research, their efficiency has been increasing. For the interface between the dc photovoltaic solar array and the ac electrical grid is necessary the use of an inverter (dc-ac converter), which should be optimized to extract the maximum power from the photovoltaic solar array. In this paper is presented a solution based on a current-source inverter (CSI) using continuous control set model predictive control (CCS-MPC). All the power circuits and respective control systems are described in detail along the paper and were tested and validated performing computer simulations. The paper shows the simulation results and are drawn several conclusions.
太阳能光伏并网接口电流源逆变器的预测控制
太阳能光伏系统是越来越多的电力生产选择,因为它们从清洁的可再生能源中产生电能,多年来,作为研究的结果,它们的效率一直在提高。对于直流光伏太阳能阵列与交流电网之间的接口,必须使用逆变器(dc-ac变换器),该变换器应进行优化,以从光伏太阳能阵列中提取最大功率。本文提出了一种基于连续控制集模型预测控制(CCS-MPC)的电流源逆变器(CSI)解决方案。文中详细描述了所有的电源电路和相应的控制系统,并进行了计算机仿真测试和验证。文中给出了仿真结果,并得出了几点结论。
