A load is a portion of the system that consumes energy. You can specify an electric load by choosing one of the three options:
An electric load will be either critical or non-critical. HOMER Grid will attempt to serve either load during normal operation, however they differ during utility outages. If an electric load is specified as critical, it will be served even during a utility outage. A non-critical load will not be served during a utility outage. They are identical if your model does not contain a utility outage.
Clicking on the Electric Load would open the following set up page.
Click the Remove button (red X next to the title) to remove the load from the schematic and model.
Electric load is the load the system must meet. In each time step, HOMER dispatches the power-producing components of the system to serve the total primary load. Click the Electric Load button to open the Electric Load Set Up page. The details of a load in a given system are sometimes not available, so HOMER can build (simulate) a load in several ways. After HOMER creates the load, you can edit it in several ways, including modifying individual time steps.
After you have added a load, you can make changes on the Electric Load page. See the Load Profile section of the help.
