| Abstract | There exists more than 280 communities in Canada that are not connected to North American electric grid due to geographic limitations. This work studies the efficiency gains from an engineering perspective as well as the potential economic benefits from complementing a Micro Gas Turbine (MGT) based micro grid with Battery Energy Storage System (BESS) to form a hybrid energy system to meet the power need, and potentially the heat need, of these geographically isolated communities. A yearly averaged profile of power demand from a typical Canadian household with 5-min resolution was adopted to represent the end users of the micro grid. The Capstone C30 of a nominal power rating of 30 KWe is the base MGT power unit assumed for this study. Considering only one cold start of the MGT per day, it was found that an operating strategy to start the MGT between 8 and 10 am minimizes the size of the battery system with an imposed restriction of operating the MGT above 90 percent of its base load; the minimum engine load requirement is designed to achieve the best system efficiency. The minimum size of the usable storage capacity of the BESS is estimated for meeting the energy storage needs for the aforementioned operating strategy. Finally, the economy of a MGT-based hybrid system is assessed by estimating the unit energy price. |
