FAQS about Frequency regulation of thermal power plant pumped storage

Do thermal units contribute to secondary LFR in pumped-storage power plants?

In both cases, the pumped-storage power plant is initially operating in hydraulic short circuit mode and the change in wind power is compensated by the turbine. In neither of these papers, the AGC system and, therefore, the contribution of thermal units to the secondary LFR were considered.

Does peak and frequency regulation affect power systems with PSHP plants?

When the more number of units in in the generation state, the more capability of frequency regulation can be provided by the PSHP. This paper proposes an optimal dispatch strategy for minimizing the operation cost for power systems with PSHP plants and battery storage considering peak and frequency regulation.

Can a PSHP plant participate in frequency regulation?

In addition, the capability of participating in frequency regulation for PSHP plants is strongly impacted by the operation state of units. When the fixed-speed unit is shutdown or in a pumping state, the unit cannot provide frequency regulation capability.

Can a fixed-speed unit provide frequency regulation capability?

When the fixed-speed unit is shutdown or in a pumping state, the unit cannot provide frequency regulation capability. When the more number of units in in the generation state, the more capability of frequency regulation can be provided by the PSHP.

What is pumped storage hydropower power (PSHP)?

Pumped storage is one of the most mature energy storage technologies. It can generate/pump for long time and has large capacity. Pumped storage hydropower power (PSHP) plants have the functions of peak regulation, valley filling, frequency regulation, and accident backup .

How much power does a synchronized thermal unit supply?

A load demand of 390 MW has been assumed to be supplied by the synchronized thermal units in all simulations; this value is an average between typical peak (530 MW) and off-peak (250 MW) power demands. Maximum power of all synchronized thermal units has been assumed to be 500 MW.

China southern power grid has invested in several pumped storage power stations

Two million-kilowatt pumped storage power stations in South China's Guangdong province were placed into full operation on May 28, which has significantly increased the consumption capacity of clean energy in the Guangdong-Hong Kong-Macao Greater Bay Area, and made the region a world-class bay area power grid with the highest proportion of clean energy.

FAQS about China southern power grid has invested in several pumped storage power stations

How many pumped storage power stations did China approve?

The country approved 110 pumped storage power stations with a total installed capacity of 148.901 gigawatts, which is 2.8 times the capacity approved during the “13th Five-Year Plan” period. China has completed 70.90 % of the total capacity target of 210 gigawatts for key implementation projects during the “14th Five-Year Plan”.

How pumped storage and new energy storage are developing in central China?

The development of pumped storage and new energy storage in Central China shows a trend of coexistence and complementarity, which is mainly due to the great importance of energy structure optimization and power system regulation capacity in the region.

Who developed pumped storage power stations in China?

Hubei Energy Group Co., Ltd., Three Gorges Construction Group Before the 14th Five-Year Plan, the development of pumped storage power stations in China was mainly carried out by power grid enterprises, namely State Grid Corporation and China Southern Power Grid Corporation.

How many kilowatts is pumped storage power station in Guangdong-Hong Kong-Macao?

The new Meizhou Pumped Storage Power Station and Yangjiang Pumped Storage Power Station have a total installed capacity of 2.4 million kilowatts, bringing the total installed capacity of pumped storage power grid in the Guangdong-Hong Kong-Macao Greater Bay Area to reach nearly 10 million kilowatts.

Which power station has the largest capacity in China?

The Yangjiang Pumped Storage Power Station, which has three 400,000-kilowatt generating units, is currently the one with the largest single unit capacity in China. In addition, the height difference between the upper and lower reservoirs of the station reaches 700 meters.

Will China's power stations reach peak carrying capacity in 2024?

Combined with the approved power stations in Central China from January 2021 to April 2024, the traditional pumping and storage design units have strong technical reserves and undertake the same number of design tasks, and may reach the peak carrying capacity in the future.
