Technical FAQs 4

Why is seasonal energy storage important?

Energy storage at all timescales, including the seasonal scale, plays a pivotal role in enabling increased penetration levels of wind and solar photovoltaic energy sources in power systems.

How does seasonal distribution affect renewables in a power system?

These events demonstrate seasonal distribution characteristics and can result in renewable inadequacy over different timescales, presenting challenges for power system planners and operators. Currently, lots of studies have focused on analyzing and modeling the seasonal variation of renewables in the power system.

Are seasonal variation characteristics related to inter-day renewable variation?

In contrast, the seasonal variation characteristics are commonly described by selected representative days in different seasons. Nevertheless, the inter-day renewable variation, such as low-renewable-output events and their seasonal distribution characteristics, might need to be fully considered.

How much difference does solar power collect between seasons?

Thus in principle a factor of 6 to 1.5 difference per solar power collecting footprint between seasons occurs, next to the diurnal day and night fluctuations, and varying cloud covers. These seasonal and diurnal influences multiply with each other to obtain the total solar power.
