Tam Sayılı Doğrusal Programlama Kullanarak Bir Mikro Şebeke Sisteminin Optimum Planlanması

Abstract

Integer linear programming can be used in many areas as well as a method used for optimum planning of a microgrid system consisting of renewable energy sources. Wind energy, photovoltaic, fuel cell and battery sources are used to meet the load of a residence. Situations such as not being able to benefit from photovoltaic throughout the day, obtaining variable values from wind energy during the day, and the capacity of the battery show that the energy sources to be used for the electricity need of the house should work within a planning. The battery is charged when the energy produced from energy sources is more than the need of the house. In cases where the energy sources are insufficient for the load requirement of the house, energy is used from the battery or fuel cell. In the study, the state of charge of the battery is also monitored. The GAMS program was used as the optimization application. The program finds out which energy source will be used in which time period and the resulting cost. In the application, which was carried out with different scenarios, which energy source should be used more and the costs were reached. According to the results of the application, it has been seen that the integer linear programming method is effective in the optimum planning of the working times of the energy resources, as it will be the most cost-effective.
