Can hybrid energy storage improve power quality in grid-connected photovoltaic systems?

This paper introduces an innovative approach to improving power quality in grid-connected photovoltaic (PV) systems through the integration of a hybrid energy storage, combining batteries and supercapacitors and a novel three-phase ten-switch (H10) inverter.

Are photovoltaic power generation systems sustainable?

Photovoltaic (PV) power generation systems are emerging as a key solution for addressing environmental challenges while satisfying the growing global demand for energy [1, 2]. These systems are highly regarded among renewable energy technologies for their versatility and sustainability.

How does PV energy storage work?

In most traditional PV systems, energy storage typically uses batteries/supercapacitors with a two-level or a three-level inverter. Existing approaches primarily focus on energy management, leakage current mitigation, or grid current harmonics.

How can a solar inverter help you save money?

This reduces the amount of electricity that homeowners are charged by the energy provider. Surplus solar energy can either be fed into the public grid, which is often being remunerated, or temporarily stored with the help of our hybrid inverter – to charge electric cars after sundown, for example.

How can PV energy improve grid stability?

Despite the benefits of PV energy, its variability and unpredictability pose challenges to grid stability . These issues can be mitigated by integrating electrical energy storage systems (ESSs) or employing hybrid energy systems, both of which enhance energy reliability .

Does battery/supercapacitor storage improve power quality for grid-connected PV systems?

Conclusion This paper has optimized the power quality for grid-connected PV systems by incorporating battery/supercapacitor storage and a novel ten-switch inverter.
