Power-functional network

Area of Science:

• Complex networks
• Power systems engineering
• Network science

Background:

• Power grids are extensively studied complex networks.
• Existing research often focuses on structural properties like shortest path length.
• A functional perspective based on power flow distribution is less explored.

Purpose of the Study:

• To introduce and define the concept of a power-flow-based power grid.
• To compare power-flow-based networks with structural and effective electrical distance networks.
• To investigate the relationships and differences among these network representations.

Main Methods:

• Calculating power flow distribution to define power-functional networks.
• Analyzing shortest path lengths for structural networks.
• Determining effective electrical distance for effective networks.
• Comparing network properties across these three models.

Main Results:

• A general positive correlation exists between structural, effective, and power-functional networks.
• Identified counter-examples where physically close nodes have functional separation.
• Observed heterogeneity in structural networks versus homogeneity in effective and power-functional networks.

Conclusions:

• Power-flow-based networks offer a novel functional perspective on power grids.
• The findings highlight the distinction between physical connectivity and functional relationships.
• The study's insights are applicable to power grids and other complex systems.
