The goal of the proposed research project is to develop a robust and useful analysis of the effects of climate change on the hydrology of the Churchill River watershed in Labrador. The partner organization, Nalcor Energy, is planning a multi-billion dollar hydroelectric development on the Churchill River and has a strong interest on the impact climate change may have on initial project engineering and operations throughout its lifespan.
The ability of observing the dynamics of an interconnected power system spread over a large geographical area in real time using synchrophasor technology enables the design of power system controllers against system wide disturbances which could lead to catastrophic failures. Currently, the synchrophasor technology is primarily used for monitoring applications and its potential for using in protection and stability control is not fully utilized.
When a company has excess power generation at its disposal, a natural course of action will be to seek to market that power. However, power markets are notoriously volatile, and this makes the cash flows that result from selling the power unpredictable and hard to plan for. The aim of this project is to help develop models for power forward prices that can be used to help manage this risk.
The use of fossil fuels for energy and chemical production is not sustainable, and it leads to increased emissions of air pollutants (SO2 and NOx) and greenhouse gases. It is thus of strategic significance to explore alternatives to fossil resources for both energy and chemicals production. Among all the potential alternatives to fossil resources, biomass is promising because it is renewable and immense. Canada is blessed with 401.9 million hectares of forest, approximately 10% of the world’s total forest cover.
Driven by economic, technical and environmental reasons, the energy sector is moving into an era where Distributed Generation (DG) will meet a large segment of increasing electrical energy demand. Local distribution companies are required to accept a given percentage of customer-owned renewable DG units in their system. Generally, DG introduces new possibilities such as shaving of peak loads and reliability enhancement.
A feasibility study will be conducted for a proposed tri-generation (generation of heat, electricity and cooling) using a Stirling engine and a ClimateWell heat activated chiller. The Stirling engine will provide simultaneous heat and electricity from burning natural gas. The heat from the engine will be transferred to either space heating, domestic hot water heating, or to the heat activated chiller. The chiller will then be able to provide space cooling.
A hi-directional converter is proposed to implement the integration of electric vehicle to the grid and household electric system. The proposed converter has two stages: a grid-connected convener. and a dc/de converter. The grid-connected converter can operate in three modes. The first of which is a battery charger. The grid-connected wi II control the power factor to unity and regulate the de bus voltage and control the input current harmonics to be low.
This research project investigates how to improve the security of operation of a power system using measurements taken at several locations of the power system. In the past, there was no technology available to synchronize these measured data, and thus the applications were limited. Now, the technology has advanced and the measured data can be synchronized using Global Positioning Satelittes (GPS). We investigate two different approaches for enhancing system stability and thus security.
The goal of this project is to research and develop a model that is suitable for BC Hydro’s application to predict the sag of a power transmission line from its induced frequency response. Transmission lines always elongate over time due to the temperature of the conductor. The ability to monitor and obtain the shape of transmission lines is one of the most important tools in evaluating power transmission line’s effectiveness in operation, maintenance and the most important, safety.
