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.
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.
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.
Conclusion This paper has optimized the power quality for grid-connected PV systems by incorporating battery/supercapacitor storage and a novel ten-switch inverter.
These features make the H10 inverter ideal for transformerless PV systems, minimizing leakage current and optimizing CMV. Additionally, it integrates with batteries and supercapacitors to address dynamic power demands and enhance system reliability, advancing PV system design for safer, more efficient renewable energy. 2.4. Dwell time calculation
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 .
