In this research, the optimal battery size for stand-alone PV system is determined using ANN model. Thus, calculation of optimum battery storage for a stand-alone PV system can be automated without needing extensive mathematical calculations or graphical analysis techniques. | Journal of Automation and Control Engineering Vol. 4, No. 1, February 2016 ANN-Based Sizing of Battery Storage in a StandAlone PV System Ahmet Afşin Kulaksız, Bayram Akdemir, and Hale Bakır Selcuk University, Engineering Faculty, Electrical & Electronics Engineering Department, Konya, Turkey Email: afsink@, bayakdemir@, haletorun5@ temperature. An application for sizing of stand-alone PV system has been presented. Ref [3] studied possibility of using an adaptive ANN to find a suitable model for sizing stand-alone PV systems, based on a minimum of input data. In this paper, ANN-based sizing of storage batteries in a stand-alone PV system is analyzed by simulations. In the next section, sizing of battery storage in a stand-alone PV system is described. Afterwards, in Section 3, employed ANN models for battery sizing is explained. Furthermore, in Section 4, the results and discussion is presented and finally, the conclusions are given in Section 5. Abstract—Sizing of electric energy storage for effective operation of photovoltaic (PV) systems is very important particularly in remote areas. Because of the intermittent nature of sun and varying inclinations of PV modules, there is no single definite rule for sizing batteries. The period of time in which the weather is cloudy and little or no sunlight is available must be considered and the number of days batteries supply the load must be computed. In this research, the optimal battery size for stand-alone PV system is determined using ANN model. Thus, calculation of optimum battery storage for a stand-alone PV system can be automated without needing extensive mathematical calculations or graphical analysis techniques. Index Terms—battery storage, PV system sizing, artificial neural networks, system availability, peak sun hour, inclination angle I. II. A stand-alone PV system shown in Fig. 1 consists of a photovoltaic array, storage batteries and power management components. The PV .
