Due to long-term reliability and very-high current in a short-time, they can be used as short term power backup and grid stabilisation device. In this work a photovoltaic system working with a supercapacitor device demonstrates its large potential in self-consumption improvement and in grid stabilisation.
In this research study, the photovoltaic system equipped with supercapacitor was investigated in order to increase renewable energy utilisation (self-consumption) and decrease grid fluctuation.
Already the PV system with two supercapacitors (2x100F) fully supplies the load demand during the day and the impact on the grid stability is smoothing of the energy feeding the grid profile. A larger number of supercapacitors does not influence renewable energy utilisation (directly) by the load.
On-Grid photovoltaic household-prosumers systems without energy storage typically undergo many fast and short-term energy flows to and from the grid due to the solar irradiation fluctuation and rapid local fluctuations of load. This negatively affects grid system stability and decreases renewable energy system self-consumption and efficiency.
Esmaili et al. have analysed energy storage with supercapacitors in order to prevent grid system frequency and voltage fluctuations caused by hardly predictable renewable energy systems. Their results show excellent fluctuation reduction in system output power.
