摘要

本文针对多功能并网光伏（PV）系统提出了一种模糊逻辑控制（FLC）与预测性直接功率控制相结合的方法，以解决因辐照快速变化而导致的逆变器直流链路电压振荡问题。整个系统由光伏系统和直流-交流逆变器组成，采用了 FLC 最大功率点跟踪 (MPPT) 算法，使直流-直流转换器在 MPP 点运行。在直流-交流逆变器的电压控制回路中采用了带有 FLC 的预测控制策略，以改善电网与光伏系统之间的功率交换。仿真结果已通过 MATLAB/Simulink 软件进行了验证，目的是提供建议控制与现有控制器相比的有效性。

An enhanced control scheme for multifunctional grid connected PV system using fuzzy and predictive direct power control

This paper presents a combination between a fuzzy logic control (FLC) and a predictive direct power control for multifunctional grid connected photovoltaic (PV) system, to solve the oscillation problem in the DC link voltage of the in-verter caused by the fast irradiation changing. The whole system consists of a PV system which interface a DC-AC inverter, a FLC maximum power point tracking (MPPT) algorithm has been adopted to operate the DC-DC converter at the MPP. The predictive control strategy is applied to the DC-AC inverter with FLC in its voltage control loop to improve the power exchange between the grid and the PV system. Simulation results have been verified through MATLAB/Simulink software for the purpose of giving the effectiveness of the suggested control against existed controllers.
