Conventional power systems are based upon ac voltages and currents. Connecting these systems is a simple matter and is done using transformers. Modern power systems wherein renewable energy sources are increasingly deployed often include dc voltages and currents. Connecting these systems is more challenging as conventional transformers will not be applicable. The proposed research is aimed at investigating and evaluating options for linking and interconnecting dc power systems. Power electronics is the enabling technology for achieving dc system interconnections.
The widespread use of phasor measurement units (PMUs) in power-grids can greatly enhance state-estimation (SE) by making use of accurate, GPS time-stamped synchronous phasor measurements. Unlike conventional SCADA measurements which are reported every 4 seconds, synchro-phasor measurements are typically available as frequently as 30-60 measurements per second. While the availability of more measurements can provide accurate state estimates in real-time, the sheer amount of data can overwhelm the computational capabilities of most data processing systems.
Bulk storage of energy is a relatively new concept in many power systems. Among various energy storage media, batteries have shown great promise as a suitable option for use in power systems. Integrating a battery energy storage system in a power grid is not a trivial task and requires extensive studies to ensure that the system is able to respond satisfactorily to its surroundings variable conditions and deliver what is expected of it.
The TransX Group of Companies is Canadas largest privately owned transportation company. Its mission is to provide integrated transportation solutions to businesses throughout North America. In the fall of 2017, the Winnipeg office of TransX discovered that diesel fuel tanks for their long-haul refrigeration units contained a sludge-like, microbial biofilm and that the fuel filters from these tanks to the generators running the refrigeration compressors were becoming clogged.

The research project aims to develop new computer models for accurate representation of battery energy storage systems that are used in modern power systems. In particular state-of-the-art modular multi-level converters with integrated dc-dc converters will be considered. The models to be developed will provide high levels of accuracy and feature low computational intensity so that study of battery systems that are integrated into the grid using advanced converter systems becomes feasible on present-day computing systems.
Bacterial infections spread from one person to another person by means of a simple touch of contaminated surfaces in healthcare units. These infections have become untreatable to most existing antibiotics, thereby accounts for significant mortality rate. Polyamyna Nanotech is developing new antimicrobial coatings that prevent spreading dangerous bacterial infections in hospitals and health care units. Mitacs sponsored intern will evaluate our products by testing them against pathogenic bacteria. This would eventually boost the product development.
Production of rutin, a high value of nutraceutical, from buckwheat hay in Manitoba has the potential to be much less labour-intensive and inexpensive compared to that produced offshore from other crops. However, the optimum drying condition of buckwheat hay and the relationship among drying conditions, harvest times and the amount of rutin in the dried hay is not known. An inexpensive and faster method to determine the amount of rutin should also be developed for the factory production of rutin.
Beef cattle play an important role in food production worldwide by making use of resources from which humans can derive little nutritional value to provide a nutrient-rich foodstuff containing protein, minerals and vitamins. However, greenhouse gases and ammonia that are produced by the cattle industry are associated with climate change. Producing nutritious beef that meets consumer demands with minimal environmental impacts requires a concerted effort from all stakeholders in the beef industry.
Battery energy storage systems are used in electric utilities for a variety of applications including back up power for critical equipment. Manitoba Hydro is evaluating two battery chemistries for use in its substations, namely Li-ion and sodium-nickel chemistries. Along with assessment of technical merits of each battery type to determine which chemistry best suits the intended application, Manitoba Hydro needs to develop schemes for maintenance and condition monitoring of these new batteries so that it can maximize their lifespan when in service and prevent any unforeseen outage.
The world has many ageing bridge structures which are being used well beyond their design service life time. It is of essential interest for the governments and public to insure safety and sustainability of bridges. One of the most advanced techniques used to investigate the conditions of bridges is the Structural Health Monitoring (SHM). The targeted bridges will be instrumented with several sensors and the data collection is performed using appropriate Data Acquisition System (DAQ).
