Within this work a simulation based tool for design optimization of PV battery systems is developed. The component models of the power electronic converters, the PV generator and the household electric load are implemented. Special attention has been paid to the model implementation of the lithium ion battery, which is based on intensive laboratory measurements. The single component models have been assembled to form an overall system model. This allows for a detailed analysis of the system states as well as of characteristic values like self-consumption and self-sufficiency. Finally the simulation model has been integrated into an optimization framework, using a genetic algorithm. Based on exemplary scenarios it is demonstrated how the tool can be used to support the design process of PV battery systems.
