Explanation of the noun of a branch road, what is the definition of a branch road?

Branch road is a professional term, one is the term of urban road, which refers to the branch road; the second is the term of the electricity industry, which refers to the power supply branch; The third is the term of network communication, which refers to network branches. According to the relationship between the change of generator output and the change of system energy margin and the relationship between it and the change of branch power flow.

On the basis of obtaining the influencing factors of generator output change on branch current change, the idea of nonlinear optimization is adopted, and the output change of all generators in the system is combined and optimized by the **-correction inner point method, and the upper and lower limits of the branch current change corresponding to different system states are calculated, and the branch vulnerability assessment index is constructed according to the upper and lower limits of constraints.

Implementation method analysis:

The issue of power grid security has always been a hot issue for many power workers. With the continuous expansion of the scale of the power grid, the power grid structure is more complex, and the initial investment or improper design will lead to the vulnerability of some parts of the power grid.

However, the superposition of the influence or uncertainty of some operating states in a specific environment often makes the fragile characteristics of these parts more distinct, and the state change of the place will affect the links associated with it, so that the impact of fragility spreads and expands within a certain range, and eventually leads to large-scale system catastrophe.

Therefore, the vulnerability of the power grid structure plays an important role in causing large-scale system catastrophe, and it is of great significance to identify the vulnerability points of the existing grid structure to maintain the security of the power grid.

The definition of a branch road is: a branch road is a professional term, one isCity roadsA term that refers to a road slip. the second is the term of the electricity industry, which refers to the power supply branch;

The third is the term of network communication, which refers to network branches.

The branch road is the connecting line between the secondary trunk road and the neighborhood road, which solves the local traffic problem and focuses on service functions. Some of the main branch roads can supplement the lack of the main road network, and public transportation lines can be set up, or they can be used as:Non-motorized vehiclesDedicated lanes. Cross-border vehicles are not allowed to pass on the branch roads, and only vehicles serving local services are allowed.

A part of a power supply system in which a branch of a circuit is each branch of the circuit that can pass the same current. , which is divided into active branches (the branches contain a power source) and passive branches. In the circuit, the branch is a single circuit element or a series of several circuit elements, forming a branch, a branch is flowing through the same current, and each branch in the circuit is called a branch.

Tributary constraints

According to the relationship between the change of generator output and the change of system energy margin and the relationship between it and the change of branch power flow, the influencing factors of generator output change on branch current change are obtained.

On the basis of nonlinear optimization, the idea of nonlinear optimization is adopted, and the output change of all generators in the system is combined and optimized by the **-correction inner point method.

The upper and lower limits of the constraints of the branch current variation corresponding to different system states were calculated, and the branch vulnerability assessment index was constructed according to the upper and lower limits of the constraints.

Finally, in the IEEE-30 bus system, the vulnerability assessment under the proposed method and the traditional optimal power flow method is compared, and the results show that it is a major advantage of this study to update the upper and lower limits of the branch current change constraint in real time according to the changes of system operating conditions.

In addition, since the combined effect of the output change of multiple generators may cause the vulnerability of the branch to not change according to the usual trend, in view of this, when the energy margin is used to obtain the branch constraint, the branch power flow change is allowed to be caused by unspecified generators, which is helpful to further explore the branch vulnerability of the power grid.

It is connected between two nodes, and each series (no bifurcation in between) circuit is a branch.

Each different color in the picture is a branch road, a total of 6.

Node: Any point in a stalking circuit that exceeds the connection of two circuits.

Tributary: A circuit between any two nodes.

The parallel Kai section circuit consists of a trunk circuit and several branch circuits, with branch points. Each branch road forms a loop with the trunk road, and if there are several branches, there are several circuits.
