Sizing Photovoltaic-Geothermal-Bio Smart Microgrid with Battery Storage Interface

This work presents a detailed sizing method to find the optimal number of photovoltaic panels and batteries (ONoPPB). The goal is to size a hybrid photovoltaic-geothermal-bio smart microgrid, which works without loss of power supply. A PC interface is established to calculate the optimal number of the components. Through this application, the user can set the meteorological data and the consumption profile and can modify the photovoltaic panels’ and batteries’ characteristics, moreover, he can add or delete various generators. The main used algorithms are the next: Hourly Radiation Prediction Algorithm, Estimation Sizing Method, Loss of Power Supply Probability Method (LPSP), Levelized Cost of Energy Algorithm (LCE). Using the lowest LCE value the optimal photovoltaic panels’ and batteries’ number can be identified. The control of this interface is very easy, entering the data and reading the results are simple. With this program, the data processing becomes practical, interactive and easy.
