Abstract

In this article, a current control algorithm is conceived for converting solar dc power into ac power of high-quality. This conversion is based only on a dc-ac converter, avoiding the use of two stage converter. The proposed algorithm is founded on tracking the maximum power point which ensures controlling the electrical power exchanged with the grid. To assure a good dynamics and reduce the control errors, a proportional resonant controllers are utilized and a self-tuning founded on particle swarm optimization is utilized. The proposal strategy goodness is verified by means of numerical simulations.

单级并网光伏逆变器的PSO-PR潮流控制
本文提出了一种将太阳能直流电转换为高质量交流电的电流控制算法。这种转换仅基于直流-交流转换器,避免使用两级转换器。该算法以跟踪最大功率点为基础,保证了与电网交换电力的控制。为了保证系统具有良好的动力学特性和减小控制误差,采用了比例谐振控制器和基于粒子群优化的自整定方法。通过数值仿真验证了所提策略的有效性。
