Investigation on Hybrid Energy Storage Systems and Their Application in Green Energy Systems

Power systems all over the world have been under development towards microgrids integrated with renewable energy-based distributed generation. Due to the intrinsic nature of output power fluctuations in renewable energy-based power generation, the use of proper energy storage systems and integrated real-time power and energy control schemes is an important basis of sustainable development of renewable energy-based distributed systems and microgrids. The aim of this paper is to investigate the characteristics and application features of an integrated compound energy storage system via simulation and a small-scale hardware system implementation. This paper first discusses the main components, working principles and operating modes of the proposed compound energy storage system. Then, a detailed design example composed of supercapacitors, batteries, and various controllers used in two typical application scenarios, peak demand shaving and power generation smoothing, of a grid-connected microgrid is systematically presented. Finally, an experimental setup with proper power converters and control schemes are implemented for the verification of the proposed control scheme. Both simulation and implementation results prove that the proposed scheme can effectively realize desired control objectives with the proposed coordinated control of the two energy storage devices.

Design of 1Gsps high-speed data acquisition card

In order to digitize the High-Frequency signal, a 12-bit 1Gsps RF Sampling data acquisition system is designed. The digital acquisition system includes an Analog-to-Digital Converter (ADC) daughter card and a data processing mother card equipped with Field Programmable Gate Arrays (FPGA) for communication, which has an external DDR3 memory module and a Gigabit Ethernet Interface. It focuses on the hardware system implementation of the daughter card and the realization of data receiving, transferring, and sending based on the FPGA. The test results show that the Effective Number of Bit (ENOB) of the acquisition card is above 9.1 Bits. Both Integral Non-Linear (INL) and Differential Non-Linearity (DNL) are anticipated. It accomplishes the requirements for engineering applications in many fields excellently.

Design and Analysis of Controller for Vehicle Ignition using FPGA

High death rates are observed after accidents due to non-wearing helmet of driver with two-wheeler. Many studies on statistics data for various parts of world had been carried out which clearly supports this statement. A new approach to address this issue along with the authentication of ownership of vehicle is proposed, which is designed in such way unless an authorized person with RFID tag wears the helmet the vehicle will not be ignited. The paper focuses on the chip design and implementation of hardware system on FPGA for vehicle. The high speed controller is designed Xilinx 14.2 ISE software with the help of VHDL programming language and synthesized on Virtex-5 FPGA. Modelsim 10.1b is used for the function simulation to test the different test cases. The developed system supports the frequency of 781.250 MHz, which is proposed as optimal solution for the intelligent system.

Coordination and Longevity in Multi-Robot Teams Involving Miniature Robots

Marsupial robot teams offer the ability to augment or replace human-based responses to hazardous scenarios such as search-and-rescue missions or monitoring toxic environments. Coordination and longevity of the members of the marsupial robotic team can quickly become burdensome as the scope of the scenario changes. To facilitate large scale operations, robotic teams must be able to function continuously with limited to no human intervention for scenarios which may not have a pre-determined length at onset. An end-to-end design and implementation of a novel marsupial system where a multi-level hierarchy allows larger robots to transport, deploy, coordinate, recover, and resupply large numbers of smaller deployable systems is outlined. The design and implementation of hardware systems for performing these actions is discussed. In addition, the algorithms which coordinate the team members are presented. Simulation illustrating the scalability of the approach is presented including experiments illustrating a light-weight vision-based autonomous docking capability.

Implementation of the 2-D Wavelet Transform into FPGA for Image

This paper presents a hardware system implementation of the of discrete wavelet transform algoritm in two dimensions for FPGA, using the Daubechies filter family of order 2 (db2). The decomposition algorithm of this transform is designed and simulated with the Hardware Description Language VHDL and is implemented in a programmable logic device (FPGA) XC3S1200E reference, Spartan IIIE family, by Xilinx, take advantage the parallels properties of these gives us and speeds processing that can reach them. The architecture is evaluated using images input of different sizes. This implementation is done with the aim of developing a future images encryption hardware system using wavelet transform for security information.
