Wind energy is by far the fastest growing renewable energy due to its free availability and environmental benefits. Maximum power extraction is a way to realize high power efficiency for Wind Energy Conversion System (WECS). This thesis focuses on studying the feasibility of implementing the Incremental Conductance (INC) method that has been used till now for Maximum Power Point Tracking in photovoltaic (PV) systems. Direct Driven Permanent Magnet Synchronous Generator (PMSG) which has no gearbox is utilized in the proposed system to reduce the cost and increase the reliability of the wind turbine. A certain power conditioning topology which includes an Intermediate Boost Converter (IBC) is employed to facilitate the use of this control method. INC method is compared with the traditional Hill Climbing Search (HCS) method and the advantages of using the INC method in some operation conditions, is validated. A Matlab Simulink model is built to verify this approach.

Solar photovoltaic (PV) energy is becoming an increasingly important part of the world's renewable energy. In order for effective energy extraction from a solar PV system, this research investigates solar PV energy generation and conversion from devices to grid integration. First of all, this dissertation focuses on I-V and P-V characteristics of PV modules and arrays, especially under uneven shading conditions, and considers both the physics and electrical characteristics of a solar PV system in the model development. The dissertation examines how different bypass diode arrangements could affect maximum power extraction characteristics of a solar PV module or array. Secondly, in order to develop competent technology for efficient energy extraction from a solar PV system, this research investigates typical maximum power point tracking (MPPT) control strategies used in solar PV industry, and proposes an adaptive and close-loop MPPT strategy for fast and reliable extraction of solar PV power. The research focuses especially on how conventional and proposed MPPT methods behave under highly variable weather conditions in a digital control environment. A computational experiment system is developed by using MatLab SimPowerSystems and Opal-RT (real-time) simulation technology for fast and accurate investigations of the maximum power extraction under high frequency switching conditions of power converters. A hardware experiment system is built to compare and validate the conventional and the proposed MPPT methods in a more practical condition. Advantages, disadvantages and properties of different MPPT techniques are studied, evaluated, and compared. Thirdly, in order to develop efficient and reliable energy conversion technologies, this dissertation compares the energy extraction characteristics of a PV system for different converter configurations. A detailed comparison study is conducted to investigate what enhancements and impacts can be made by using different bypass diode schemes. It is found that compared to micro-converter based PV systems, the central converter scheme with effective bypass diode connections could be a simple and economic solution to significantly enhance PV system efficiency, reliability and performance. Lastly, the development of coordinated control tools for next-generation PV installations, along with energy storage units (ESU), provides flexibility to distribution system operators. The objective of the control of this hybrid PV and energy storage system is to supply the desired active and reactive power to the grid and at the same time to maintain the stability of the dc-link voltage of the PV and energy storage system through coordinated control of power electronic converters. This research investigates three different coordinated control structures and approaches for grid integration of PV array, battery storage, and supercapacitor (SC). In addition, other applications including single-phase Direct- Quadrature (DQ) control and ramp rate limit control are presented in this dissertation. Index Terms - solar photovoltaic, semiconductor physics, I-V characteristics, P-V characteristics, bypassing diodes, uneven shading, power electronic converters, maximum power point tracking, digital control, computational and hardware-based experiments, battery and supercapacitor, control coordination, single-phase DQ control, and ramp rate control.

Abstract: This dissertation discusses application of advanced power electronics in small size wind energy and hybrid systems. A new control method for maximum power tracking by employing a boost converter at a wind turbine system, using permanent magnet machine is introduced. Output voltage of the generator is connected to a fixed dc-link voltage through a rectifier and the boost converter. A maximum power-tracking algorithm calculates the reference speed as the control signal for the converter. The converter uses this signal to control the output power of the generator, by controlling the output voltage of the rectifier and input current of the converter. A current regulated voltage source inverter maintains the output voltage of the converter at a fixed value by balancing the dc-link input and output power. Moreover, a new speed estimator for maximum power tracking and a novel vector control approach are introduced. The speed estimator only needs two measurements to estimate the generator speed for maximum power-tracking. Furthermore, since the system maintenance is important and in wind energy systems the generator is not easily assessable, a robust technique for on-line condition monitoring of stator windings is introduced. In this technique the generator terminal voltage and current are utilized to monitor the stator winding condition to prevent catastrophic failure. Also a hybrid system consisting of a wind turbine, a photovoltaic, and a fuel cell is introduced. A simple control with dc-dc converter is used for maximum power extraction from the wind and sun. Due to the intermittent nature of both the wind and photovoltaic sources, the fuel cell unit is added to ensure continuous power flow. The fuel cell is controlled to provide the deficit power when the combined wind and photovoltaic sources cannot meet the net power demand. The proposed system is attractive owing to its simplicity, ease of control and low cost. Chapter 5 focuses on the design of a novel Power Conversion System to convert the energy from the hybrid system into useful electricity and provide requirements for power grid interconnections. The motivation behind developing this system is to reduce the overall cost of hybrid systems.

The first systematic, quantitative appraisal of power density, offering detailed reviews of power densities of renewable energy flows, fossil fuels, and all common energy uses. "There's no author whose books I look forward to more than Vaclav Smil." --Bill Gates In this book, Vaclav Smil argues that power density is a key determinant of the nature and dynamics of energy systems. Any understanding of complex energy systems must rely on quantitative measures of many fundamental variables. Power density--the rate of energy flux per unit of area--is an important but largely overlooked measure. Smil provides the first systematic, quantitative appraisal of power density, offering detailed reviews of the power densities of renewable energy flows, fossil fuels, thermal electricity generation, and all common energy uses. Smil shows that careful quantification, critical appraisals, and revealing comparisons of power densities make possible a deeper understanding of the ways we harness, convert, and use energies. Conscientious assessment of power densities, he argues, proves particularly revealing when contrasting the fossil fuel-based energy system with renewable energy conversions. Smil explains that modern civilization has evolved as a direct expression of the high power densities of fossil fuel extraction. He argues that our inevitable (and desirable) move to new energy arrangements involving conversions of lower-density renewable energy sources will require our society--currently dominated by megacities and concentrated industrial production--to undergo a profound spatial restructuring of its energy system.
