Solar Power System Modeling and Performance Analysis Jiaqi Wang Faculty of Engineering and Computer Science University of Denver

Solar Power System Modeling and Performance Analysis Jiaqi Wang Faculty of Engineering and Computer Science University of Denver Author: Jiaqi Wang Title: Solar Power System Modeling and Performance Analysis Advisors: WenZhong Gao Degree Date: August 2011 Abstract At present the main source of our power and energy needs are from fossil fuel; almost all transportation tools and nearly 70% of electrical power are produced by fossil fuel. But unfortunately these materials are limited in our planet, with obvious drawback such as pollution. So looking for new kinds of energy supply is an urgent matter. Solar-powered photovoltaic system provides a clean energy solution to this problem. It is developing fast all over the world in terms of both research work and actual applications. It is estimated that the power supplied by solar energy can provide 10 percent of United States power needs. This thesis mainly discusses photovoltaic system modeling from the beginning of site selection to system sizing. Some tools are used during the project. A GIS application is used to help developers in the preliminary studies. Photovoltaic system simulation software PVsyst involves the system components setting and sizing process. Two types of systems are built in this study: stand-alone system and grid connected system; the location is set at Denver, Colorado. For each system the array mounting, analysis of loads and modules selection are studied. The simulation is performed after the system model is completed, the results includes loss diagrams, system energy yields and system efficiencies. At last the economic analysis and comparison between the two types of PV systems is analyzed.

Performance of a Single-Stage UPS System for Single-Phase Trapezoidal-Shaped AC-Voltage Supplies Praveen K. Jain, Senior Member, IEEE, Jos´e R. Espinoza, Student Member, IEEE, and Hua Jin, Member, IEEE

Performance of a Single-Stage UPS System for Single-Phase Trapezoidal-Shaped AC-Voltage Supplies Praveen K. Jain, Senior Member, IEEE, Jos´e R. Espinoza, Student Member, IEEE, and Hua Jin, Member, IEEE

 Abstract— A high-performance single-stage UPS system for single-phase ac power supply systems is presented. The topology generates a trapezoidal-shaped load voltage that is synchronized with the ac supply, therefore, a small dc-link capacitor is required. This feature leads to a high-input power factor (0.94 at nominal voltage), and due to the single-stage structure, high efficiency (93% at nominal voltage) is also achieved. Moreover, in both cases the supply current spectrum presents low-order harmonics, all of which satisfy IEC 555. The high performance is validated using both resistive (linear) and diode RC (nonlinear) loads. The dynamic performance of the UPS system is also analyzed under different transient conditions. Specifically, the supply to battery, battery to supply transition, load transient, and supply/battery-voltage transients are performed. They show a transfer time of 500 s (from ac supply to battery) and overvoltages of at most 15%. The dynamic and static evaluations are performed on a 1-kVA UPS system. The design guidelines for the key components and control parameters are also included.
Index Terms— AC mains synchronization, PWM inverter, single-phase single-stage conversion topology, trapezoidal-shaped ac output voltage, UPS.

ABSTRACT
This venture "Simulation and Implementation of Γ-Z-Source Inverters" is made out of Voltage-sort Γ-Z source inverters are proposed in this letter. They utilize a remarkable Γ-molded impedance arrange for boosting their yield voltage notwithstanding their standard voltage buck conduct. Contrasting them and different topologies, the proposed inverters utilize lesser parts and a coupled transformer for delivering the high-pick up and regulation proportion all the while. The got pick up can be tuned by changing the turns proportion γΓZ of the transformer inside the limited scope of 1 < γΓZ ≤ 2. This prompts to lesser twisting turns at high pick up, as compared to other related topologies.

 Keywords - Embedded-Z-source, quasi-Z-source, T-source, Trans-Z-source, Z-source, Γ-Z-source inverters.

 Abstract: This paper presents line-interactive transformerless Uninterruptible Power Supply (UPS) with a fuel cell as the prime energy source. The proposed UPS consists of three major parts (i.e., an output inverter, a unidirectional DC–DC converter, and a battery charger/discharger). Non-isolated topologies of both the unidirectional converter and battery charger/discharger ensure transformerless operation of the UPS system. A new topology of high gain converter is employed for boosting the low voltage of the fuel cell to a higher DC link voltage, with minimum semiconductor count, and high efficiency. A high-gain battery charger/discharger realizes the bidirectional operation between the DC link and the battery bank. Besides, it regulates the DC link voltage during the cold start of fuel cells and keeps the battery bank voltage to only 24 V. A new inverter control scheme is introduced that regulates the output voltage and minimizes the total harmonic distortion for non-linear loading condition. The proposed control scheme integrates proportional-resonant control with slide mode control, which improves the controller’s performance in transient conditions. The proposed UPS system is validated by developing a 1-kVA experimental prototype.
