Real‐time experimental implementation of an LMS‐adaline‐based ANFIS controller to drive PV interfacing power system

Abstract

This paper presents the experimental implementation of a LMS-Adaline-based ANFIS controller of an improved power-quality photovoltaic (PV) generating system connected to the grid. The proposed system applies an adaptive neuro-fuzzy inference system (ANFIS) to control the DC-DC boost converter integrated with PV to achieve the maximum power point tracking (MPPT) operating condition. For power-quality improvement at the point of common coupling (PCC), Adaline (adaptive linear element)-based control algorithm is used to estimate the reference grid currents. To achieve high performance with fast dynamic response during transition and to regulate constant the DC and the AC voltages without saturation phenomena, ANFIS controller is employed. The real-time benchmark realised in the laboratory, to implement the setup, uses a dSPACE controller. To demonstrate the performance of the proposed configuration, the system is first simulated offline under numerous critical scenarios. The experimental results are then presented to validate the concept.

High-Performance Pure Sine Wave Inverter with Robust Intelligent Sliding Mode Maximum Power Point Tracking for Photovoltaic Applications

“…intrusion compensation. Equations (7) and (8) can be allowed to converge to the equilibrium for a limited time. Then, the system dynamics (5) will also be converged to the equilibrium for a limited time while the sliding regime is approached.…”

“…From the mathematical derivation and proof of robust SMC described in Equations (9) and (11), they represent the equivalent control term with non-singularity, and the sliding control term with intrusion compensation. Equations (7) and (8) can be allowed to converge to the equilibrium for a limited time. Then, the system dynamics (5) will also be converged to the equilibrium for a limited time while the sliding regime is approached.…”

“…Many MPPT control methods have been put forward to fulfill these requirements, including disturbance observation method, linear iteration method, fuzzy control method, etc. [5][6][7][8]. However, the changes in the maximum power output of PV panels are virtually related to solar illumination and ambient temperature.…”

Design and performance analysis of improved Adaline technique for synchronization and load compensation of grid‐tied photovoltaic system

“…High harmonic content, poor power factor, voltage regulation problems become dominant, thereby requiring mitigation techniques. Distribution static compensator (DSTATCOM), Dynamic voltage restorer and Unified power quality compensator are some popular custom power devices used as solutions by power engineers. These custom power devices use some form of synchronizing technique viz.…”
