Market Coupling as the Universal Algorithm to Assess Zonal Divisions
Adopting a zonal structure of electricity market requires specification of
zones' borders. In this paper we use social welfare as the measure to assess
quality of various zonal divisions. The social welfare is calculated by Market
Coupling algorithm. The analyzed divisions are found by the usage of extended
Locational Marginal Prices (LMP) methodology presented in paper [1], which
takes into account variable weather conditions. The offered method of
assessment of a proposed division of market into zones is however not limited
to LMP approach but can evaluate the social welfare of divisions obtained by
any methodology.Comment: 5 page
The Scheme of a Novel Methodology for Zonal Division Based on Power Transfer Distribution Factors
One of the methodologies that carry out the division of the electrical grid
into zones is based on the aggregation of nodes characterized by similar Power
Transfer Distribution Factors (PTDFs). Here, we point out that satisfactory
clustering algorithm should take into account two aspects. First, nodes of
similar impact on cross-border lines should be grouped together. Second,
cross-border power flows should be relatively insensitive to differences
between real and assumed Generation Shift Key matrices. We introduce a
theoretical basis of a novel clustering algorithm (BubbleClust) that fulfills
these requirements and we perform a case study to illustrate social welfare
consequences of the division.Comment: 7 page
