Category Photovoltaic Sources

Prerequisites

Readers should be familiar with basic semiconductor physics, circuit analysis, and with the fundamentals of DC/DC converters circuits and control. The book has been conceived as an advanced textbook, designed primarily to meet the demands of a course taught at postgraduate (M. Sc., Ph. D. etc.) level. However, the authors have made an effort to present each subject to be understandable by MSc students. For this reason, the book can be also used as supporting test in some Engineering or Physics courses.

Acknowledgments

The authors are very grateful to Mr. Antonio Sauro and Mr. Giuseppe Scordato, technicians at CNR-ISSIA, for their irreplaceable contribution in building the emulator prototype.

How to Use the Book

First of all, this book represents a tool to obtain a PV source model and to reproduce it by a power converter.

Chapter 1 gives an overview of the Energy conversion from the Sun to the Earth.

The readers interested on modeling issues can read the first part, in particular Chap. 2 and 3; furthermore, they can utilize Chap. 4 to identify the related parameters.

The readers interested on emulation of the source can read the Chap. 6 if they want to have the scenario on existing solutions, or directly Chaps. 7 and 8 to design the DC/DC converter for emulation of the source. It should be noted that the approach used for emulating a PV source can be extended to other sources having their characteristics lying on I-V plane.

To Whom this Book is Addressed

This book is intended primarily to meet the demands of postgraduate level students but it should also prove useful to the professional engineers and researchers dealing with the problem of creating an indoor virtual PV plant for testing MPPT techniques, non-ideal operating conditions, control for the grid or load interfacing, etc. Moreover, the book can be useful to:

• Researchers and Engineers who work in the field of renewable sources;

• Engineers and Physicists who deal with PV sources modeling;

• Mathematicians and Statistics who work with parameters identification techniques.

Originality of the Approach

The book has the specificity to propose a novel method for the analysis of several issues related to PV plants operation, doing without the use of a real installation. This approach, leading to the design and setup of a virtual indoor photovoltaic generator, i. e., the PV emulator, implies the transversal investigation of several disciplines going from solar cell physics to power electronics and control. In this sense, the book gives a new perspective on this subject. As a matter of fact, these disciplines are presented in a synergic way to solve the problem of PV source emulation.

The reader can find, joined in a unique text, all information related to the emulation of a PV source (model choice, parameters identification, software implementation, design and control of the power amplifier)...

Outline of the Book

The book is divided into two parts.

Part I embraces the chapters from 1 to 5; it is dedicated to the PV source modeling.

Part II includes the chapters from 6 to 8; it refers to PV emulation issues, including design and realization.

Part I

Chapter 1. This chapter deals with the energy generated inside the Sun that reaches the Earth. It is a fantastic trip in which the reader is involved with the two main concepts of very big (the scale of the universe and the produced energy) and of very small (inside semiconductor).

Chapter 2. After its trip as electromagnetic wave, energy reaches the Earth. Now, it is transformed into electric energy...

Preface

Photovoltaic (PV) industry is growing exponentially and the availability of specialized equipment for the laboratory tests is becoming crucial especially for manufacturers and laboratories working in the field of power electronics related to PV plants.

All people, concerned with renewable sources’ applications, experience the need of laboratory equipment to carry out measurements and tests. In particular, in the field of PV generators, the difficulties are tied to the use of an actual outdoor plant for performing tests involving the PV source as well as various kinds of loads, such as resistive loads, DC motors, storage batteries, and inverter-connected loads with their maximum power point trackers (MPPT).

A real PV plant needs a wide outer surface and high costs...
