Abstract

A new analog technique is proposed in order to track the maximum power point (MPP) of PV panels. The proposed technique uses the well-known simple functions of electronic circuits. The proposed technique is validated by applying it to boost based off grid PV system. The simulation of the PV system was done on the circuit oriented simulator Proteus-ISIS. A good efficiency of the analog technique (more than 98%) was registered. The variation of irradiation was introduced in order to study the robustness of the proposed analog MPPT technique.

Highlights

The production of domestic and industrial energy is based, in large part, on a limited resource: oil
The proposed Maximum Power Point Tracking (MPPT) technique, power converter, and PV arrays models are implemented in the Proteus-ISIS circuit oriented simulator
The difference between the generated real power and the optimal panel power contributes to the performance assessment of the proposed analog technique

Summary

Introduction

The production of domestic and industrial energy is based, in large part, on a limited resource: oil. Many scientific researches have been carried out, in the field of nuclear energy production, and in the sector of unlimited energy sources, such as wind power generation and energy transformation In the latter case, the design, optimization, and realization of photovoltaic systems are topical issues since they lead to a better exploitation of solar energy [2]. Many MPPT control methods have been developed and implemented, like Fuzzy Logic Method [4,5,6,7], perturbation and observation (P&O) method [5, 6, 8], and Incremental Conductance (Inc.Con.) method [7, 9,10,11] These techniques are generally complex and expensive to implement [4, 9, 12]. A new analog MPPT technique suitable for PV system applications is presented and validated by simulations
