Originally, OptiCE model included solar photovoltaic (PV), wind turbine, diesel generator, and battery bank for off-grid applications, in particular water pumping for irrigation. The model has been continuously developed and new power sources, power-to-heat conversion technologies, and storage systems have been developed and integrated.

OptiCE is an essential tools for researchers, consultants and decision makers working in the fields of renewable energies, hybrid power systems, distributed energy generation, and mini/microgrids.

The model has been already implemented for research and consultant activities regarding:

  • Optimization of PV and hybrid water pumping systems for irrigation in China;
  • Optimization of PV/wind hybrid power systems for shrimp farm in Thailand;
  • Wind driven heat pump for detached houses in Sweden;
  • Optimization of residential district in Gothenburg;
  • Optimization of PV and wind systems equipped with different storage technologies to increase photovoltaic self-         sufficiency in residential building of Sweden;
  • Optimization of hybrid PV/wind/battery system for a farm in Sweden;
  • Optimization of solar home system in Namibia and Colombia;

The GIS version of OptiCE has been used to study the water-food-energy nexus of irrigation during drought conditions  in Nebraska and in Sweden.

OptiCE is an open source code for simulation, optimization, and design of hybrid power systems for off-grid and on-grid applications. OptiCE models clean energy technologies integrated in microgrids or as distributed generation in larger grids. The model is written in Matlab® language and uses genetic algorithms to find the best power sources, storage system, and back-up source combination to minimize life cycle cost and maximize renewable power system reliability. It covers the whole chain of energy systems including mainly 6 areas, i.e., renewable energy, conversion technologies, mitigation technologies, intelligent energy uses, energy storage and sustainability.
