| Market Impacts of Geographic Dispersion of Wind Energy in AlbertaThis thesis presents a methodology to simulate the energy production from hypothetical wind farms in Alberta in order to examine potential future market impacts of a geographically dispersed wind fleet in Alberta. The wind farms’ output are simulated using the Canadian Wind Atlas (CWA) Modelled Historical data (HMD), a publicly available hourly Numerical Weather Prediction (NWP) model and calibrated to historic output from existing wind farms in the province to determine if the data available from the CWA (hourly wind speeds, temperature, and air density), were sufficient to simulate new wind farms in Alberta. A generic loss coefficient was empirically calculated to estimate power output from a wind farm compared to the manufacturer’s power curve at simulated wind speeds from the CWA. By comparing modelled wind farm performance to historical market data from wind farms operating in Alberta, it was found that the CWA tends to underestimate wind speeds from 7:00 am until noon for the spring months, as well as misrepresenting wind speeds for the southwest region of the province (near communities with existing wind farms in Pincher Creek and Fort Macleod). Outside of the southwest of the province, the simulated wind farm’s annual energy production, using the data from the CWA HMD, were within a percentage error between 1% to 10% for wind farms that operated over the same timeframe. By applying this methodology to regions of the province without existing wind farms, the output of new hypothetical wind farms was created in different locations in Alberta. The output of hypothetical wind farms was allows for market impacts simulations of new wind farms in Alberta using the Aurora market model from Energy Exemplar. Preliminary results from Aurora’s model simulation shows that increases in wind energy development will lower market prices during periods of high wind as would be expected. This work enables future analysis examining the potential market changes of a more geographically diverse wind fleet in the province. | Publication | 2020-09-29 | Natalia Vergara Bonilla |

| Framework for design and optimization of a retrofitted light industrial space with a renewable energy-assisted hydroponics facility in a rural northern canadian communityThe purpose of this study is to develop a design framework for retrofitting a light industrial building with a hybrid renewable energy-assisted hydroponics farming system for production of fresh food in rural north Canadian communities. This design protocol is targeted at facilities in rural areas of northern Canada, which could benefit from better access to fresh food, especially given the harsh climate as well as the long and limited transport routes. The process includes 1) a review of the existing building; 2) estimation of design loads for system sizing, such as temperature and humidity control, adequate lighting, airborne carbon, and water; 3) multi-objective genetic algorithm optimization of the hybrid renewable energy system for minimal operating cost and emissions; and 4) comparison of costs and greenhouse (GHG) emissions of the proposed farming operation with the traditional food supply chain. To demonstrate the proposed methodology, a case study building in a rural community in Alberta, Canada was evaluated for retrofit. The results showed that the GHG emissions generated from local hydroponic lettuce production, aided by a hybrid renewable energy system (HRES), are three times greater than those emitted by transporting an equivalent quantity of food from southern California, USA. On the other hand, the life cycle cost showed that the cost to produce lettuce from the case study facility is comparable to the price of lettuce available from traditional import, which shows a promising potential to provide fresh and cost-competitive food in the community, among other qualitative benefits gained from this empowering opportunity.
