Power Generation Planning of Galapagos’ Microgrid Considering Electric Vehicles and Induction Stoves
Islands located far away from the mainland and
remote communities depend on isolated microgrids based on
diesel fuel, which results in significant environmental and cost
issues. This is currently being addressed by integrating renewable
energy sources (RESs). Thus, this paper discusses the generation
planning problem in diesel-based island microgrids with RES,
considering the electrification of transportation and cooking to
reduce their environmental impact, and applied to the communities
of Santa Cruz and Baltra in the Galapagos Islands in
Ecuador. A baseline model is developed in HOMER for the
existing system with diesel generation and RES, while the demand
of electric vehicles and induction stoves is calculated from vehicle
driving data and cooking habits in the islands, respectively.
The integration of these new loads into the island microgrid is
studied to determine its costs and environmental impacts, based
on diesel cost sensitivity studies to account for its uncertainty. The
results demonstrate the economic and environmental benefits of
investing in RES for Galapagos’ microgrid, to electrify the local
transportation and cooking system.
