(b) Capacity of the pumped hydro storage station was 2400 MW. From Fig. B, Fig. 7, the power stability of the transmission lines must be ensured by abandoning wind or solar power when the WFs or PVs independently operate, owing to the power fluctuation characteristics, leading to a relatively low utilisation efficiency of renewable energy.
Capacity mechanisms should account for the capacity value of electricity storage. In electricity markets around the world, the substantial increase of intermittent renewable electricity generation has intensified concerns about generation adequacy, ultimately driving the implementation of capacity remuneration mechanisms.
Barriers exist for electricity storage to participate in some capacity mechanisms. Specification of a capacity mechanism affects technology mix and generation adequacy. Call options with a strike price increase the competitiveness of electricity storage. Low storage capacity credits create a strong bias towards conventional power plants.
In this setting, the conventional power plant has constant difference costs since it is not affected by the required storage duration. Contrary, the capacity of the small storage unit is already derated under relatively low storage duration requirements due to its limited storage volume.
