Storage time of reserve power station

How many mw can a power station produce?

The power station can produce 1,200 MW (=4 units * 300 MW/unit) of hydropower and regulate storage capacities of about 8.5 million m 3 and 8.7 million m 3 in upstream and downstream reservoirs, respectively. The upstream reservoir possesses an emergency reserve storage of 0.5 million m 3 to tackle emergency incidents.

What is the difference between rated power capacity and storage duration?

Rated power capacity is the total possible instantaneous discharge capability of a battery energy storage system (BESS), or the maximum rate of discharge it can achieve starting from a fully charged state. Storage duration, on the other hand, is the amount of time the BESS can discharge at its power capacity before depleting its energy capacity.

What is storage duration?

Storage duration is the amount of time storage can discharge at its power capacity before depleting its energy capacity. For instance, a battery with 1 MW of power capacity and 4 MWh of usable energy capacity will have a storage duration of four hours.

What is the storage capacity of Gangnan hydropower station?

This PSPS uses Gangnan reservoir as the upper reservoir with the total storage capacity of 1.571×10 9 m 3, and uses the daily regulation pond in eastern Gangnan as the lower reservoir with the total storage capacity of 3.5×10 6 m 3. For the application of the pumped storage unit, Gangnan hydropower station owns the ability of load regulation.

What is cold reserve in a power system?

Cold reserve in a power system is that reserve capacity which is available for service but normally not ready for immediate loading. A Cold reserve is ensured by special reserve units with small start-up and spin-up time. Period of the cold reserve start-up is varies from 2 to 24 hours and more.

How to optimize pumped-storage power station operation?

Propose a novel optimization framework of pumped-storage power station operation. Optimize pumped-storage power station operation considering renewable energy inputs. GOA optimizes peak-shaving and valley-filling operation of pumped-storage power station. Promote synergies of hydropower output, power benefit, and CO 2 emission reduction.
