"", which is a feat of pumped hydro storage in the Guangdong-Hong Kong-Macao Greater Bay Area. In 2023, facing the whole countryElectricityThe load has reached a new highNew energyWith the increasing proportion of installed capacity, pumped storage is a mature, economically advantageous and large-scale development potentialClean energy, playing an increasingly important role. Six pumped storage power stations in the Guangdong-Hong Kong-Macao Greater Bay Area will be activated more than 30,000 times in 2023 through 31 units, and the power generation capacity will exceed 10 billion kWh for the first time, an increase of 27 over the previous year36%, which is equivalent to the annual electricity consumption of 5.14 million households. This tremendous achievement sets a new milestone for the global pumped storage industry.
In order to improve the response speed and accuracy of power grid dispatching, China Southern Power GridEnergy storageThe company has set up a centralized control center for pumped storage multi-plant stations in Panyu production base. PassedInternet of Things technologyTo realize the rapid identification of equipment information and the convenient operation of error-proof, the centralized control center realizes the remote centralized control and control of all pumped storage units in the Guangdong-Hong Kong-Macao Greater Bay AreaEfficiency2 to 3 times more than the traditional model. This innovation improves the power grid dispatchingEfficiencyand accuracy, providing strong support for the operation of pumped storage power stations.
In order to ensure the normal operation and stable scheduling of pumped storage units, China Southern Power GridEnergy storageThe company has adopted a series of technical management measures. Among them,Black startIt is one of the important functions of the pumped storage power station, which is self-starting through the pumped storage unitTransmission linesCharging, starting other generator sets, etc., pumped storage power plants can be injected quickly under extreme conditionsElectricityto quickly restore the power grid. In 2023, pumped storage power stations in the Guangdong-Hong Kong-Macao Greater Bay Area were successfully completed eight timesBlack startTest, among which Meizhou, Guangzhou, Yangjiang three pumped storage power stations for the first time with 500 kV lineBlack startThe test more realistically simulated the situation that the power grid was completely black.
In addition, the Southern Power GridEnergy storageThe company has also realized a comprehensive emergency duty management, and the operation personnel directly undertake the daily emergency and routine fault handling work, emergency responseEfficiencyDramatically improved. With the strong support of six pumped storage power stations, the daily pumped storage power generation capacity of the five southern provinces exceeded 50 million kWh for the first time.
In order to improve the core technical level and reliability of pumped storage power stations, China Southern Power GridEnergy storageThe company has carried out key technical research. Among them, the switchgear of pumped storage is considered to be the last shortcoming of pumped storage power station. In 2023,China Machinery Industry FederationA product appraisal meeting was organized, China Southern Power GridEnergy storageThe company and its supplier, Xikai Electric, have made a major breakthrough by showcasing a switchgear set of pumped storage units in Meizhou. The equipment has higher reliability in configuration design, longer service life, and more convenient installation and commissioning. This achievement provides a more reliable guarantee for the operation of pumped storage power stations.
Pumped storage asClean energyhas developed into a well-established business technologyEnergyReserve technology. Pumped storage power stations in the Guangdong-Hong Kong-Macao Greater Bay Area have made a major breakthrough in 2023, further boosting the development of the entire industry. In the future, pumped storage power plants will continue to play an important role, especially in the futureNew energyThe proportion of installed capacity continues to increaseElectricityIn the case of increasing loads. At the same time, with the continuous progress of technology and the continuous reduction of costs, pumped storage power stations will receive more and more attention and investment from all over the world.
In the future development, it is necessary to further strengthen the coordinated operation with the power grid, improve the flexibility and responsiveness of dispatching, and further improve the load response capacity and dispatching capacity of pumped storage power stations. Strengthen emergency management and key technology research, and improve the safety, reliability and sustainable development capacity of pumped storage power stations. At the same time, new business models need to be explored to promote the integration of pumped storage power stationsEnergyTransform service providers to provide more value-added services.
In conclusion, pumped hydro is one with great potentialClean energytechnology is gradually being commercially deployed. Pumped storage power stations in the Guangdong-Hong Kong-Macao Greater Bay Area have made a major breakthrough in 2023, setting an example for the development of the industry. In the future, with the continuous innovation of technology and the deepening of application practice, pumped storage power stations will be in the futureEnergyplay an increasingly important role in the transformation and achieve sustainabilityEnergyDevelopment goals to contribute.
