Title: Distributed Grid Control – The Next Frontier for Power Electronics
Summary: The power infrastructure is poised for dramatic change. Drivers include growth in non-schedulable distributed generation, improved economic, operational and energy efficiency, and higher grid resiliency under cyber-attacks and natural disasters. The utilities have adopted smart grid initiatives and Internet of Things methods to augment the available centralized command & HV side control with sensors (AMI, V/I), back-office data management & demand/system optimization to squeeze more performance out of the grid. However, it is becoming clear from field data that utilities today do not have the tools to manage the future grid with the precision needed. This presentation will show a new approach for distributed grid-edge control that allows the existing infrastructure to operate more efficiently in terms of energy, assets and economics, and enables new objectives such as high levels of PV hosting on distribution feeders, and the realization of grid-side demand management. Distributed control also offers a possible leap-frog opportunity for utilities in emerging markets to realize significantly higher performance at potentially lower cost. The presentation will present field data to validate the concepts being presented.

Title: Hybrid Renewable Energy Standalone Systems
Summary: Several isolated areas in the world currently use only diesel generators (DGs) to serve their requirements of electrical energy. However, the use of DGs has many drawbacks: 1) high cost of electricity, 2) air and noise pollution, 3) Loss in fuel efficiency and maintenance cost. To remedy those problems it is better to generate power from a cost-effective, environmental friendly renewable energy sources (RESs) such as wind, solar, hydro, biomass, etc. RESs are clean and almost available all over the planet but are intermittent in nature, especially wind and solar power generations. This makes their integration to micro-grid with DG difficult, especially if the local grid is not connected to the main grid. Hybrid standalone system consists of many elements such as photovoltaic panels, wind turbines, DG, energy storage system, AC and DC loads, dump load etc. Most of these elements are connected to the AC or DC bus via power electronic devices. In this presentation many possible hybrid renewable energy standalone systems will be discussed. Control of some of the systems will be discussed in detail.

Title : Power Electronics Intelligence at the Network Edge (PINE)
Summary: This presentation puts forth a vision for scalable distribution grid integration of energy resources such as rooftop photovoltaics (PV) and electric vehicles (EVs). The outputs of these resources vary temporally in an unpredicted manner. Therefore, they bring substantial challenges to utilities via-a-vis massive deployment of such resources. By leveraging the fact that most of the distributed energy resources are interfaced with power electronics converters, we propose a fully decentralized architecture for achieving the main objectives of utility companies, namely, (1) end user voltage regulation; and (2) delivery system loss minimization. The proposed framework provides a bottom-up approach to integrating many such distributed resources without substantial capital investment. This framework, termed as Power Electronics Intelligence at the Network Edge (PINE), provides a possible pathway towards supporting a very high level of PV and EV penetration in future distribution systems. The operational benefits to end users as well as the utilities are elaborated with the IEEE 123-bus test system.

Title:Google Little Box Challenge One-Million US Dollar Inverter Design Competition
Summary: With fast development of wide bandgap (WBG) semiconductor devices and their promise on superior conducting and switching features that allow ultrahigh-efficiency power electronics design. In July 2014, Google announced to hold a Little Box Challenge a one-million US dollar inverter design competition. The initial entry exceeded more than 2000 teams, but only about 100 final report submissions, and only 18 teams were selected for the hardware testing, which was conducted at the US National Renewable Energy Laboratory (NREL). In the end only three teams passed the overall testing, and the winner was the one with highest power density. Virginia Tech is the only university team that went through all the tests successfully and was placed top three finalist. Major challenges of the design include how to deal with the low-frequency second harmonic ripples, output filter size minimization, electromagnetic interference (EMI), and thermal management. This presentation will discuss briefly on the figure of merit of WBG devices silicon carbide (SiC) and gallium nitride (GaN) and their selections. A summary review goes to how the teams select inverter circuit topologies, pulse width modulation techniques, double line frequency suppression, design of harmonic and EMI filters, and packaging techniques.

Title: Sensorless Drive of IPMSM absolute position sensing
Summary: The position sensorless control of Interior Permanent Magnet Synchronous Motor(IPMSM) has been evolved for last 20 years. And the performance of sensorless drive with high frequency signal injection can be reached that of sensored drive with 10 bit encorder. However, mostly, the electric angle of the rotor position of IPMSM has been identified and used for the torque control of IPMSM with sensorless control. Recently, with some modifications of design of IPMSM and the signal injection method, the absolute position of the rotor in mechanical angle could be identified and used not only for torque control but also for the rotor position control. In this talk, the sensorless control techniques for absolute position identification of IPMSM will be introduced and the performance of the control be discussed. And, the problems and future possible developments would be suggested.
