Techno-economic criteria to evaluate power flow allocation schemes

TL;DR

This paper introduces new quantitative criteria for evaluating power flow allocation schemes in electricity networks, focusing on fairness, plausibility, uniqueness, and stability, and applies them to four prominent schemes in a German case study.

Contribution

It develops a comprehensive set of evaluation criteria for power flow allocation schemes and demonstrates their application to real-world scenarios.

Findings

Different schemes vary significantly in fairness and plausibility.

The criteria help identify schemes with desirable stability and uniqueness properties.

Application to a German case study illustrates practical implications.

Abstract

We develop novel quantitative techno-economic evaluation criteria for power flow allocation schemes. Such schemes assign which nodes are responsible for which proportion of power flows on a line in a meshed electricity transmission network. As this allocation is, as such, indeterminate, the literature has proposed a number of dedicated schemes. To better understand the implications of applying different schemes, our criteria comprise their (i) fairness, (ii) plausibility, (iii) uniqueness, and (iv) stability. We apply, illustrate, and discuss these criteria for four prominent schemes based on results of a detailed electricity sector model with linear power flow for a German mid-term future case.
