Quantitative modeling to design a best value Micro-Grid

It seems like everyone’s talking about microgrids, and the correct energy mix for their off-grid power needs.

What really is the best energy mix for your project,

and how can people say so with confidence? 

At Out of the Box Energy Solutions, we use HOMER (Hybrid Optimization of Multiple Energy Resources) software. At its core, HOMER is a simulation model that we use to develop quantitive models of thousands of systems composed of, all possible combinations of the equipment that we consider suitable for your project, including capital costs, operational costs and operational lifespan of the equipment.

 

The outcome is a design process that identifies the least-cost options for your microgrid or other distributed generation electrical power system. This allows us to design with confidence solutions that ensure our client’s investment in a Smart Hybrid Power System gives them the highest possible return on their investment. 

Out of the Box Energy Solutions simulates the operation

of a hybrid microgrid for an entire year,

to design the best value option

Engineering and Economics

working side by side.

 

By using quantitive modeling our goal is to find the least cost combination of equipment while ensuring a robust design to fulfil the electric loads of a project.  As with all quantitive models, the number of combination of components and commercial variables run into the thousands.

HOMER software chronologically simulates an electrical system for an entire year for every viable combination of the selected components.  We provide the software with: the location of the project, the technologies to consider (solar, wind, battery and others) an understanding of the electrical load that needs to be served, and some estimates of costs for different possible components (for example, Rands per kW for solar photovoltaic panels, Rands per liter of petrol, nominal discount rate).

  • the location of the project,
  • the technologies to consider (solar, wind, battery and others)
  • an understanding of the electrical load that needs to be served, and
  • some estimates of costs
    • for different possible components costs (for example, Rands per kW for solar photovoltaic panels)
    • for different operational costs (for example, Rands per litre of fuel)
    • for economic variables (for example the nominal discount rate)

Originally developed at the US Department of Energy’s National Renewable Energy Laboratory, HOMER has been downloaded by over 140,000 people in literally every country in the world.
