Why is excess electricity a problem in off-grid hybrid systems?
The presence of excess electricity constitutes a significant limitation to the wider implementation of renewable capacity in off-grid hybrid systems. Surplus power leads to reductions in energy efficiency, power supply reliability, total system stability, and affordability of renewable-based systems.
How does an off-grid system work?
Unlike grid-tied systems that connect to the electricity network, off-grid systems operate independently. They rely heavily on solar panels as the primary power source. These panels generate electricity during the day, and excess energy is stored in batteries for use during the night or on cloudy days.
What happens if a HREs is integrated with a utility grid?
When the HRES is integrated with the utility grid, the generated surplus power after charging the storage units can be injected into the grid, which leads to near-zero excess electricity . In these systems, purchasing electricity from the grid can lead to peak-shaving, which causes less surplus electricity generation from the HRES.
Is energy surplus a problem?
Based on literature, exceeding 10% of the energy surplus level indicates suboptimal energy efficiency in the renewable system. Surplus electricity is not a problem in some parts of the world, such as Europe, where most regions have access to the synchronous electrical grid.
