    Abstract

    Maximum Power Point Tracking or MPPT is a tool for the dynamical optimization of the power produced by a photovoltaic or PV array. But MPPT is useful not only in PV applications, but also whenever the power produced by the power source must be maximized regardless from some exogenous, or uncontrollable, parameter. Algorithms used for MPPT operation can also be useful for the dynamical optimization of other functions describing the operation of any system or power plant.

    In this tutorial Drs. Petrone and Spagnuolo discuss the possible applications of MPPT-like algorithms in different contexts related to renewable energies. They also consider the optimization of the performances of one of the most frequently used MPPT algorithms, the Perturb and Observe method.

    The tutorial will also provide an overview of other MPPT approaches, implemented by means of analog circuitry and by adopting a digital control.Finally, the authors examine some differences concerning the application of the photovoltaic MPPT concept at field level, string level and module level, thus introducing one of the most significant challenges of present day solar systems, Building Integrated Photovoltaics or BIPV.

    Abstract

    The tutorial presents an overview of the fundamentals of automatic control of fuel cells, focusing on the application of Model Predictive Control (MPC) as an advanced control technique suited to this kind of systems. The tutorial presents some advantages of using Model Predictive Control (MPC) to regulate the air flow and stack temperature as well as to minimize fuel consumption, addressing some real-time issues and showing experimental results. The tutorial also deals with energy management when electric energy storage (battery or ultracapacitors) is integrated in the fuel-cell system. After completing this course you should have an understanding of:
    • The dynamic behavior of a fuel cell
    • The main control issues in fuel-cell systems
    • The automatic control of air supply and stack temperature
    • The optimization of fuel consumption with or without storage
    • The advantages of using MPC for these systems

    Abstract
    This course will provide a presentation of the electrical subsystem for important distributed generation technologies. The main focus will be on wind turbines and photovoltaics. The analysis of grid interconnection issues, assessment procedures and methodologies will also be discussed. This will cover typical interconnection schemes, power quality and fault level considerations and protection requirements. The course will also provide a presentation of the latest grid-code requirements for the connection of large wind farms. This will address basic requirements regarding fault ride-through, active and reactive power regulation, as well as their fulfillment by the technologies available today. Finally, the course will present the latest developments in microgrids and discussion of grid integration issues in autonomous island power systems.

    Abstract

    In the field of renewable energy designing power processing systems characterized by high efficiency (>98%) and reliability (MTBF>20-25 years) remains a challenge. Only when systems exhibit these key features will renewable sources really be competitive with traditional ones.

    Even though a number of new topologies and electronic devices have been proposed for improving the converter characteristics, these efforts have fallen short. This is because there has not been a similar evolution in control strategies, where the classical linear approach continues to be applied intensively.

    The objective of this tutorial-which is part of the IEEE eLearning Library Industrial Electronics Series- is to introduce the basic concept of nonlinear control by focusing on an emergent control technique which can be used for improving the performances of photovoltaic and fuel cell power processing systems.
