This invention discloses an off-grid multi-energy complementary spatial
layout optimization method based on island
topography, belonging to the field of spatial
layout optimization technology. It includes: constructing a
spatial database by acquiring island topographic, meteorological, and planning data; building a multi-
source data consistency evaluation model based on spatial resolution, timeliness, and coordinate consistency; eliminating prohibited construction zones and identifying
energy development spatially compatible units; establishing a spatial
adaptation, techno-economic, and
operational reliability constraint
system with the dual objectives of minimizing the levelized cost over the
entire life cycle and maximizing energy self-sufficiency; and using a multi-objective iterative optimization
algorithm to solve for the
Pareto optimal solution set, ultimately delineating the preferred areas and coordinates for
wind power, photovoltaic, tidal / wave, and
energy storage facilities and outputting the spatial
layout plan. This invention effectively solves problems such as complex island
topography, heterogeneous data, poor off-grid power supply stability, and unreasonable layout.
