Simultaneity of consumption and solar energy production of a Hungarian household Attila Sándor Kazsoki, Bálint Hartmann   2017/04/25

Abstrac

Nowadays, the electricity production with renewable energy plays an increasingly important role in which photovoltaic (PV) systems play significant role as well. This kind of technology is predominant on the household level for. The reason, that a wide output range can be created, and each of the individual consum-ers can be customized, furthermore its aesthetic, manageability and financial characteristics are also positive. In this publication the simultaneity of the production of a household size small power plant and the quarter-hourly consumption of a household was analyzed, and the sizing of an energy store system (ESS) in the event of power supply interruption was shown. Analysis of the data shows the impact of production and consumption in individual seasons, and illustrates the extent of it. In addition the simultaneity of production and consumption was shown on diagrams in each month and season. The simultaneity has been very low, but it could be improved by using ESS. In this study the sizing methodology and the financial aspect of an ESS has been displayed.
