“…In the case of Brochet, the peak load was almost twice the average load, however, in some communities it can be as high as five to ten times the average load (Lipman, 1994). And, like in the case of Brochet, the peak values usually occur for a small fractions of the total year (Pelland et al, 2012).…”

“…For example, instead of treating all community electricity demand as base load, the load can be divided into critical and non-critical categories. This information would further allow sizing diesel generators to closely match the load (Pelland, Turcotte, Colgate, & Swingler, 2012). For in-depth analysis, the HOMER model can be coupled with other electricity models such as MATLAB and SIMULINK to investigate how voltage and frequency variations affects power quality supplied by electricity system with increased penetration of renewable energy (especially wind) (Islam, 2012).…”

As the existing diesel generators are nearing the end of their operational lifespan, this study uses the HOMER model to determine an optimum electricity system design at Brochet that has high electrical reliability, least cost, and low emissions. Three potential power generation options were considered and evaluated, namely: 1) only diesel, 2) only wind, 3) a mix of both. The wind-diesel hybrid system performed best for all the evaluation criteria. While maintaining high reliability, this hybrid system design resulted in 19 % reduction in electricity cost, and 30 % reduction of CO 2 when compared to the existing electricity system at Brochet. Thus, this study concludes that the wind-diesel hybrid system is the optimum electricity system design for Brochet and proposes this system replace the existing system.ii Acknowledgement

This paper presents a concept to improve the dynamic response, efficiency, productivity, and fuel consumption of Hydraulic Mining Shovels (HMS) using a high power energy storage system to supplement the existing diesel-powered generators. A 2.25 MW ultracapacitor system is applied to improve the sluggish dynamic response of the diesel engine during sudden load changes and to limit the engine power requirements by maintaining an optimal engine speed. When the load rate of change increases above a specified rate limit, the ultracapacitor system supplement power to support loads in order to limit the power ramp rate for the generator. In addition to engine dynamic improvement, the ultracapacitor system supports the engine during peak power demand allowing for a smaller engine size for the machine, which results in higher fuel savings and less exhaust emissions. An interleaved bi-directional DC/DC converter is designed to interface between the ultracapcitor bank and main DC bus. Sophisticated multilayer control strategies are designed, implemented, and applied to the system to perform complete machine power management while keeping the DC bus voltage stable. Modeling and experimental results for an 8000 HP HMS with the novel electrification architecture have also been presented.Index Terms − Electrification, energy storage, mining shovel, peak shaving, power leveling, power management, power ramp rate.

“…On a PV-diesel hybrid mini-grid in rural Canada, Pelland et al, (2012) found that reducing the non-5 essential commercial loads that had been acting essentially as "dump loads" for an over-sized 95 kW diesel generator allowed for the installation of a second 30 kW diesel generator. 7 After installation of the smaller generator, non-essential loads were turned off on nights and weekends and the larger generator was only run during commercial hours, reducing fuel use of the mini-grid by over 20,000 L/year, or by approximately 20%.…”

“…It should also be noted that on some mini-grids, electricity rates may be highly subsidized so that they no longer provide the necessary price signals to encourage conservation. Pelland et al (2012) found that mini-grid customers in Canada were using inefficient electric baseboard heaters and suggested that adding an inverted block rate would encourage conservation behavior on the diesel mini-grid.…”
