Pumped storage scheduling with minimum abandoned solar power

Can pumped storage power stations be used at abandoned mines?

However, there have been few studies on the establishment of pumped storage power stations at abandoned mines, and studies on the configuration of WP and PV capacity using pumped storage have focused only on the economy, reliability or environmental protection. Several major research gaps exist in previous studies:

What is a pumped storage system?

Pumped storage (PS) systems are energy storage systems that are characterized by fast start-up and strong peak load capacity. Pumped storage hydropower is also the most mature and widely used large-scale energy storage technology .

Do pumped storage/wind/photovoltaic integrated systems benefit from integration?

However, the capacity configuration of pumped storage/wind/photovoltaic integrated systems (PSWPISs) is still an important factor that affects the benefits of integration. Much research has been performed on the optimal configuration of energy storage systems containing pumped storage.

Can combined pumped storage/wind/photovoltaic/ hydrogen production solve grid-connected instability and light abandonment problems?

Ren et al. established a combined pumped storage/wind/photovoltaic/ hydrogen production system to solve the grid-connected instability and wind and light abandonment problems of traditional power generation systems.

How many PS power stations can be installed in abandoned mines?

By combining the abandoned mine data, eight PS power stations with different parameters were selected for the optimal configuration study. The installed capacity of PS4 and PS5 is consistent with the standard PS mentioned above, but the rated head and adjustable storage capacity are inconsistent.

Why is pumped storage important?

Constructing a new power system with renewable energy as the main component is an important measure for coping with extreme weather and maintaining the stability and efficiency of the power system; in particular, pumped storage is an effective means of smoothing fluctuations in the wind and photovoltaic power output.
