Abstract
The object of this project is to optimize a PV power system for a domestic application by using the software HOMER. First, we have analyzed the different types of PV systems in reference to the relationship with the grid. Then, we have chosen the most suitable option for our application. In our case, the choice has been an off-grid system. The off-grid PV system has been developed with the software HOMER. This software requires you to add the loads, components and resources which take part in the system you want to design. For the loads you can introduce your consumption measured data or model it with HOMER. The software can also model the loads by using its database and give the typical values of consumption for each month or type of building and also simulate the typical variations of consumption in a day. For the components, HOMER has a big list of components, since generators of all kinds, to storage systems and some types of electronic components. For the components you have to introduce the cost of each one and after you can fix the quantity or select the option of HOMER optimization which gives you the best option. Then you have to introduce the resources. It allows you to introduce your own data or use its database. HOMER has a tool which lets you to get the data of temperature, wind and sun of your installation only by introducing your location. Once we have designed our system, HOMER allows you to simulate the installation and with its database and its algorithms gives you the optimized solution. This solution is the cheapest possible configuration of components which allows you to accomplish the required necessities of the system. In our simulation we have analyzed also the influence of the capacity shortage in our system. The capacity shortage is measured in a percentage respect the whole year and it represents the moments when the installation does not satisfy the energy requirements of the loads. We have seen that as high is the value of the capacity shortage less is the cost of the installation. So for designing the installation we have to choose or accomplish the requirements of the load in all instants of the year or not satisfy the energy necessities of in a few moments and save a big quantity of money. Key words: PV off-grid system, HOMER, simulation software, optimized solution, capacity shortage.
