HOMER Optimization Model HOMER Getting Started Guide 3/30 Welcome to homer What is homer? HOMER, the micropower optimization model, simplifies the task of evaluating designs of both off-grid and grid-connected power systems for a variety of applications. When you design a power system, you must make many decisions about the configuration of the ystem What components does it make sense to include in the system design How many and what size of each component should you use? the large number of technology options and the variation in technology costs and availability of energy resources make these decisions difficult. HOMER's optimization and sensitivity analysis algorithms make it easier to evaluate the many possible system configurations How do l use homer? To use HOMER, you provide the model with inputs which describe technology options component costs, and resource availability. HOMER uses these inputs to simulate different system configurations or combinations of components and generates results that you can view as a list of feasible configurations sorted by net present cost. Homer also displays simulation results in a wide variety of tables and graphs that help you compare configurations and evaluate them on their economic and technical merits. You can export the tables and graphs for use in reports and presentations When you want to explore the effect that changes in factors such as resource availability and economic conditions might have on the cost-effectiveness of different system configurations you can use the model to perform sensitivity analyses. To perform a sensitivity analysis, you provide Homer with sensitivity values that describe a range of resource availability and component costs. HOMER simulates each system configuration over the range of values. You can use the results of a sensitivity analysis to identify the factors that have the greatest impact on the design and operation of a power system. you can also use HoMER sensitivity analysis results to answer general questions about technology options to inform planning and policy decisions. how does homer work? Simulation HOMER simulates the operation of a system by making energy balance calculations for each of the 8, 760 hours in a year. For each hour, HOMER compares the electric and thermal demand in the hour to the energy that the system can supply in that hour and calculates the flows of energy to and from each component of the system. For systems that include batteries or fuel-powered generators, HOMER also decides for each hour how to operate the generators and whether to charge or discharge the batteries lOMER performs these energy balance calculations for each system configuration that you want to consider. It then determines whether a configuration is feasible i e. whether it can meet the electric demand under the conditions that you specify and estimates the cost of installing and operating the system over the lifetime of the project. the system cost calculations account for costs such as capital, replacement operation and maintenance fuel, and interest HOMER V2. 1(April 2005 HOMER Optimization Model HOMER Getting Started Guide 4/30 Optimization After simulating all of the possible system configurations, HOMer displays a list of configurations, sorted by net present cost(sometimes called lifecycle cost), that you can use to compare system design options Sensitivity Analysis When you define sensitivity variables as inputs, HOMER repeats the optimization process for each sensitivity variable that you specify. For example, if you define wind speed as a sensitivity variable, homer will simulate system configurations for the range of wind speeds that you specify HOMER on the internet TheHomerWebsite,www.nrel.gov/homer,containsthelatestinformationonthemodel as well as sample files, resource data, and contact information HOMER V2. 1(April 2005 HOMER Optimization Model HOMER Getting Started Guide 5/30 Step one: Formulate a question that HOMER can help answer HOMER can answer a wide range of questions about the design of small power systems. It is useful to have a clear idea of a question that you want Homer to help answer before you begin working with HOMER. Examples of the kinds of questions that homer can answer are Is it cost-effective to add a wind turbine to the diesel generator in my system? How much will the cost of diesel fuel need to increase to make photovoltaics cost effective? Will my design meet a growing electric demand? Is it cost-effective to install a microturbine to produce electricity and heat for my grid-connected facility? For this exercise let us assume that diesel generators typically serve small loads in a remote area and that we want to use homer to find out whether it makes sense to add wind turbines to such systems. The question we will use HoMer to help answer is: How do changes in average wind speed and fuel price affect the feasibility of adding wind turbines to a diese/-only system design? HOMER V2. 1(April 2005 HOMER Optimization Model HOMER Getting Started Guide 6/30 Step two: Create a new HoMER file A HOMER file contains all of the information about the technology options, component costs and resource availability required to analyze power system designs.

HOMER file names end in. hmr, for example ation and contains the results of any calculations HOmER makes as part of the optim WindVsDiesel, hmr When you start HOMER, it looks for the most recently saved file and opens it.

The schematic may include components that are not in the optimal design In this exercise, HOmER will simulate systems that include wind turbine and diesel combinations to answer the question How do changes in average wind speed and fuel price affect the feasibility of adding wind turbines to a diese/-only system design?
