Abstract
This paper posits on a reasonable quantification of the intrinsic reliability offered by an existing transmission network structure for a given set of power transactions. We rely on the concept of transmission reliability margins in the lines, which act as safety nets to protect system security in the face of aleatory uncertainties in the availability of transmission lines and epistemic uncertainty in accounting for the load demand patterns. This is proposed to be used as an equitable basis to charge the users of transmission network, generation and load consumption entities alike, over and above the usage charges levied according to the ‘extent-of-use’ normative. Using the tandem combination of deterministic and probabilistic load flow studies in conjunction with power flow tracing procedures, we propose a step-by-step procedure to arrive at a novel transmission pricing methodology. A six-bus Roy Billinton Test System (RBTS) is employed to illustrate the conceptual feasibility and the computational procedure.
