【 摘 要 】

The paper describes proposed techniques used for simple simulation of a hybrid energy system in a building. An interactive software tool is presented that can be downloaded and used for any purpose free of charge. Based on selected household electrical equipment, solar irradiance, PV system design and ESS parameters an annual simulation is made based on hourly time resolution. The outputs presented in charts as well as tables show the distribution of energy sources (grid, PV), the effect of ESS operation, self-sufficiency of PV system and its utilization of PV throughout the year. The simulation is real-time based so the system design can be easily manually optimized to achieve specific goals (e.g. specified self-sufficiency at minimal costs). As the simulation if based on Excel sheets, it can be easily accustomed by users with specific requirements.
