6 FAQs about [UHV Profit Analysis in Energy Storage 9 Blocks]

How do you calculate UHV utilization?

Here, θ represents the annual utilization of UHV lines, which can be expressed as follows: (1) θ = ∑ t = 1 T P t T ∗ P, where P t is the active power of the transmission line at the time t, T is the number of hours in a year, which is generally 8760; and P ̇ is the transmission line’s rated power.

What is the utilization rate of UHV lines in North China?

The utilization rate of UHV lines sent to North China is mostly concentrated at approximately 36%. The role of UHV lines is particularly critical in the uneven distribution of sources and loads in China. Therefore, the utilization rate of UHV lines should be further improved to send clean power from the west to the east.

What is UHV power grid interconnection?

Power grid interconnection through UHV power transmission lines optimizes the resource allocation across a wider spectrum and increases the power supply to the receiving-terminal load centers in the eastern region.

What are the output characteristics of UHVAC power transmission?

The output characteristics of UHVAC power transmission are not specific to a certain type of power generation because of the distribution characteristics of the power flow. The sending-end power supply of UHVAC power transmission is similar to that of UHVDC, which is generally a combination of wind–PV-thermal power.

How does a uhvav power transmission system work?

UHVAC power transmission channel can exhibit multiple nodes in the middle, which can form a network structure. In practice, the power flow regulation of the UHVAV power transmission system is restricted by the power flow distribution, the ramp rate of generation units, and the stability constraint of the transmission line.

Why do we need UHV lines in China?

The role of UHV lines is particularly critical in the uneven distribution of sources and loads in China. Therefore, the utilization rate of UHV lines should be further improved to send clean power from the west to the east.
