Can a Regional Grid Corporation own a power plant?
3. The regional grid corporations can possess the PSPS or a minority of power plants for emergency use and load regulation. This document affirms the existence legitimacy of the PSPS in China, laying a system foundation for its development.
What is the availability of grid-based power?
Though the grid is connected all the time, however, the power availability in the grid is very poor. Here, we have considered the availability of grid-based power, means the number of hours power is available in the grid. In this study, the different availability of grid-based power (6 h, 8 h and 12 h) are considered for the analysis.
What voltage does a power plant produce?
Power plants generally produce electricity at low voltages (5– 34.5 kilovolts (kV)). “Step up” substations are used to increase the voltage of generated power to allow for transmission over long distances. Typical transmission voltages include 115 kV, 138 kV, 230 kV, 345 kV, 500 kV, and 765 kV.
Can a large-capacity power supply meet the demand of the grid?
As to the CFU, the large-capacity one can also meet the demand of the power grid for load regulation in theory. But, when the unit operates for load regulation, especially when it is bearing the peak load, the equipment failure will increase, affecting the safe operation of the unit and the reliability of power supply.
Is 6H grid-based power a realistic approach to rural electrification?
It is important to mention that in the conventional rural electrification programme through grid extension the quality and availability of power are very poor. So, for the present rural electrification programme, 6 h of availability of grid-based power can be considered a realistic approach.
How does China's Economic Development affect the power grid?
With the rapid economic development in China, the energy demand and the peak-valley load difference of the power grid are continuing to increase. Moreover, wind power, nuclear power, and other new energy sources also develop very fast.
