overview

Electric Power Distribution Modeling and Simulation for Feeder Analytics and Distributed Energy Resource Integration - FirstEnergy (2013 - present). This project builds advanced feeder models from a variety of utility data sources, including geographic information systems (GIS), supervisory control and data acquisition (SCADA) and supplemental sources. Work continues on system design methods for voltage and reactive power control on systems with large amounts of photovoltaic (PV) generation.
Photovoltaic Output Variability Impacts on the Distribution System - Duquesne Light (2013 - present). This project collects high-resolution output data from PV generators dispersed over a geographic area. Modeling and correlation techniques are being developed to assess the realistic impact of PV output fluctuations on the distribution system voltage, without making worst-case assumptions of perfectly correlated output fluctuations.
Photovoltaic Inverter Modeling - National Energy Technology Laboratory/Regional Universities Alliance/Grid Technologies Collaborative (2013 - present). This project is developing PV inverter models that are suitable for islanding, fault detection and temporary overvoltage studies in situations with high penetration of PV on the distribution system, especially with multiple inverter types and sizes. The models and analysis techniques range in complexity from symmetrical components (adapted to PV inverters) to time-domain simulation. Validation by lab testing is being planned.
Medium Voltage Direct Current (MVDC) Technology Development - ABB Corporate Research (2012 - present). This project explores the use of MVDC converters and controllers to integrate renewable energy in situations with weak AC grid ties, or no AC grid ties. Analysis and controller design is being addressed from the lowest level (phase-locked loop stability) to the highest (dispersed micro-grids).
High-Speed Induction Motors Using Nanocomposite Magnetic Materials - ARPA-E/SolarADEPT (2012 - present). This project developed a high-speed induction motor design with reduced weight and cost. It was developed as a potential application for a new nanocomposite magnetic material developed at another institution. Finite element models of the material were developed for design applications, and benchmarked against laboratory test results. PV interconnection requirements were also analyzed for their economic impacts on PV inverter applications of the new magnetic material.
A Heuristic Nonlinear Constructive Method for Electric Power Distribution System Reconfiguration (doctoral research, completed April 1998). Distribution feeders in North America usually operate in a radial configuration. A reconfiguration algorithm arranges tie switches to minimize losses (or some other objective), while meeting the radial condition and other constraints. This reconfiguration algorithm starts with all operable switches open, and at each step, closes the switch that results in the least increase in the objective function. The objective function is defined as incremental losses divided by incremental load served. A simplified loss formula is used to screen candidate switches, but a full load flow after each actual switch closing maintains accurate loss and constraint information. A backtracking option mitigates the algorithm's greedy search. This algorithm takes more computer time than other methods, but it models constraints and control action more accurately. A network load flow is used to provide a lower bound on the losses and a quality measure of the final solution. The algorithm was tested on several sample systems published by other authors, and solved a problem with line voltage regulators that other published algorithms cannot handle. The algorithm was implemented in the Electric Power Research Institute (EPRI) DEWorkstation software product currently used by several utilities.
