7. Embedded C Programming: A Practical Course Introducing Programmable Microprocessors

Author

Laverty, David M., Milliken, Jonny, Milford, Matthew, and Cregan, Michael

Abstract

This paper presents a new laboratory-based module for embedded systems teaching, which addresses the current lack of consideration for the link between hardware development, software implementation, course content and student evaluation in a laboratory environment. The course introduces second year undergraduate students to the interface between hardware and software and the programming of embedded devices; in this case, the PIC (originally peripheral interface controller, later rebranded programmable intelligent computer) microcontroller. A hardware development board designed for use in the laboratories of this module is presented. Through hands on laboratory experience, students are encouraged to engage with practical problem-solving exercises and develop programming skills across a broad range of scenarios. (Contains 9 figures and 2 tables.)

18. Electrical Heating Emissions on the Island of Ireland

Author

Kerr, William D., Laverty, David M., and Best, Robert J.

Abstract

This paper shows the effect on household greenhouse gas emissions if standalone or supplementary electric heating was to replace conventional heating methods, based on the present day electrical grid. While having the capability to improve future grid effectiveness and dynamic stability through the potential incorporation of demand side management (DSM). The All-Ireland system has been used in this paper as an example of a network which has been experiencing a significant increase in renewable generation. To show the potential of the electric heating methods the characteristics of existing domestic heating systems will be discussed, in terms of their heat output against their exhaust emissions (gCO2e/kWh). This will then be compared to that of the grid CO2 Intensity, showing the frequency and duration of the possible emission savings involved when using electricity as a main or supplementary heating source.

48. OpenPMU technology platform for Synchrophasor research applications.

Author

Laverty, David M., Vanfretti, Luigi, Best, Robert J., Morrow, D. John, Nordstrom, Lars, and Chenine, Moustafa

Abstract

OpenPMU, the Open Source Phasor Measurement Unit, is a platform for the development of Synchrophasor measurement technology in an open source manner. The OpenPMU design modularizes the key components of a Phasor Measurement Unit (PMU) into three subsystems; measurement, phase estimation and telecoms. The advantage to the researcher is that the interfaces between each subsystem are open and human readable, allowing for rapid integration of new work into an existing framework. This allows for new work to be prototyped rapidly and tested in an online environment. This paper introduces the OpenPMU technology platform. The subsystem modules and the methods of exchanging data are described. Present work on the platform is discussed and an open invitation to join the development process is extended to all.
