Evaluating the sensitivity of grid integration level for a multi energy hubs

Renewable energy integration into multi energy grids (MEG) is gradually getting popular due to the rapid depletion of fossil fuel resources and the global concern on GHG emissions through fossil fuel based energy conversion technologies. However, seasonal changes in solar and wind energy potentials make it challenging to increase the renewable energy capacity especially for urban applications where demand for energy services show a complex variation. According to recent literature, connecting multi energy hubs (MEHs) to a MEG can be a promising method to address the aforementioned challenge. However, a quantitative analysis of the improvement of system autonomy and renewable energy integration through multi energy hubs is missing. In this work, Homer microgrid design tool is used to analyze the sensitivity of the grid integration level to the renewable energy integration process of a multi energy hub. Heating and electricity demand of the MEH and the energy flow through Solar PV panels, wind turbines, boiler and battery bank are evaluated on hourly basis. Homer, microgrid simulation tool is used to evaluate the sensitivity of electricity cost to renewable energy capacity and energy storage.
