HOMER Quickstart is a quick-and-easy tool to help you better understand the powerful HOMER (Hybrid Optimization of Multiple Energy Resources) model used in HOMER Pro —the global standard in microgrid design. With Quickstart, you can: Better understand what HOMER is and what it does. Become more familiar with hybrid power systems. LIBRARY - HOMER ENERGY The HOMER Library contains all of the components, incentives, and tariffs you can use to model energy systems. The library contains nine categories listed on the left side of the page: Storage, Generator, PV, Wind TurbineEach category consists of various types of library

OF ELECTRICITY

The second term in the numerator is the portion of the annualized cost that results from serving the thermal load. In systems, such as wind or PV, that do not serve a thermal load (H thermal =0), this term is zero.. The COE is a convenient metric with which to compare PV TEMPERATURE COEFFICIENT OF POWER If the brochure does not specify the temperature coefficient of the open-circuit voltage but contains a graph showing the current-voltage (IV) curve at different cell temperatures, as shown below, you can use the graph to calculate the temperature coefficient of the open-circuit

voltage.

IMPORTING A LOAD FROM A TIME-SERIES FILE You can import a load from a time-series file using one of several formats that HOMER Pro recognizes. Tip: You can import data with any time step down to one minute.

GENERATOR LIBRARY

The controller you use in your HOMER model determines how to dispatch the various generation sources to meet the load. HOMER has three built-in dispatch strategies: Cycle Charging, Load Following, and Generator Order.You can also choose to write your own dispatch in MATLAB and link it to HOMER using the MATLAB Link..

GENERATOR LIFETIME

Prime-power, liquid-cooled diesel. 7 - 10,000. 20,000 - 80,000. Natural gas microturbine. 25 - 500. 50,000 - 80,000. Because its lifetime is specified in operating hours, the more frequently the generator operates, the shorter its lifetime is in years. This affects the economics of the system because more frequent replacements leads

to higher

PHOTOVOLTAIC (PV) LIBRARY Converter. The Converter tab contains inputs to specify the dedicated inverter (for AC panels) or maximum power point tracker (for DC panels). The inputs are similar to those for the Inverter/MPPT for the Photovoltaic page under Design, and are described in that help section.. Temperature

GRID LIBRARY

The Grid Library contains saved definitions of custom grid configurations. You can view existing grid definitions, modify advanced grid parameters, and save new grid definitions that you can

then add to

PM EMISSIONS PENALTY Use the particulate matter (PM) emissions penalty to penalize systems for their production of particulates. HOMER uses this input value when calculating the Other O&M cost. GENERATOR PROPORTION OF SULFUR EMITTED AS PARTICULATE MATTER The generator proportion of sulfur emitted as particulate matter is the fraction of the sulfur in the fuel that is emitted as particulate

matter.
