摘要

本文旨在通过能量重构的方式，对光伏逆变器的新型“无源分数阶比例积分导数(PFoPID)控制器”进行建模，使其在不同大气状态下通过P&O系统实现最大ppt。根据无源性概念，除了q轴电流外，与直流电流和直流电压相关的存储最初是为光伏系统建立的，其中每个变量都将被系统地检查，并仔细保留有利条件，以便利用光伏系统的特点。其中，剩余能量通过FoPID控制模型进行重构，控制约束通过一种新的混合算法进行最优调整，该算法混合了Cat Swarm Optimization (CSO)和Firefly algorithm (FF)的概念，从而获得最佳的控制性能。由于同时包含了FF和CSO的概念，因此所采用的模型被称为FF-CSO组合方案(Combined FF-CSO scheme, CFF-CSO)。

PFoPID CONTROL DESIGN OF GRID-CONNECTED PV INVERTER FOR MPPT USING HYBRID ALGORITHM

This paper aims to model a novel “passive fractional-order proportional-integral-derivative (PFoPID) controller” for photovoltaic (PV) inverter via reshaping energy, in such a way that the MPPT is attained through P&O system under diverse atmospheric states. Depending on passivity concept, storage, related to the DC-link current and DC-link voltage, in addition to q -axis current is initially build-up for a PV system, where every variable will be examined systematically when the advantageous terms are retained carefully so as to exploit the features of PV system. Here, the residual energy is reshaped by the FoPID control model, where the control constraints are optimally tuned by a new hybrid algorithm, which hybrids the concept of Cat Swarm Optimization (CSO) and Fireﬂy Algorithm (FF), so that a ﬁnest controlling performance could be attained. As both the concepts of FF and CSO are in-cluded, the adopted model is known as Combined FF-CSO scheme (CFF-CSO).
