Kiribati dengzhanwo pumped storage power station

What is pumped-storage power station?

The pumped- storage power station can achieve long-term storage of large-capacity power by itself. The multiple-energy- combined pumped-storage station can also improve the quantity of new energy connecting to the power grid on the premise of guaranteeing the stability and safety of the Global Energy Interconnection 240 power grid.

Can pumped-storage power station 239 improve the response speed?

The joint operation of the optical storage system Vol. 2 No. 3 Jun. 2019 Jingyan Li et al. Prospect of new pumped-storage power station 239 with sufficient capacity and the pumped-storage power station can improve the response speed of peak modulation, frequency modulation, and phase modulation of the power grid.

How can pumped-storage systems improve power-compensation response speed?

The new-generation pumped-storage station can automatically track power-grid frequency change and quickly regulate active power. Electrochemical energy storage can improve power-compensation response speed. Variable-speed pumped-storage units can achieve real-time automatic frequency tracking.

What is Kiribati's energy consumption?

Primary energy demand. Kiribati’s energy consumption, which is dominated by imported fossil fuels (52%) and coconut oil (42%), has been steadily increasing over the last few years. The residential sector is the largest consumer of energy, followed by land transport.

How much power does Kiribati have?

The PUB serves more than 57,000 people in South Tarawa, which has the highest demand at 24.7 gigawatt-hours (GWh) in 2019. Kiribati’s outer islands are served largely with solar home systems, and Kiritimati island, the second largest load center (1.65 GWh in 2016), has a separate power system not managed by the PUB. 6.

Can variable-speed pumped-storage technology improve the operational flexibility of traditional power stations?

The operational flexible of the traditional pumped-storage power station can be improved with variable-speed pumped-storage technology. Combined with chemical energy storage, the failure to achieve second-order response speed and the insufficient safety and reliability of pumped-storage power units could be solved.
