A Multipurpose Matrices Methodology for Transmission Usage, Loss and Reliability Margin Allocation in Restructured Environment

Abstract

In the era of power system restructuring there is a need of simplified method which provides a complete allocation of usage, transmission losses and transmission reliability margin. In this paper, authors presents a combined multipurpose matrices methodology for Transmission usage, transmission loss and transmission reliability margin allocation. Proposed methodology is simple and easy to implement on large power system. A modified Kirchhoff matrix is used for allocation purpose. A sample 6 bus system is used to demonstrate the feasibility of proposed methodology.

Transmission pricing using power flow tracing methodology with consideration N-1 security criterion

“…In this paper authors adopt the power flow tracing method [12] based on Modified Kirchhoff matrix (K m -1 ). In many literatures, power flow tracing method is referred for the calculation of the usage of the branch in the power system.…”

“…where t P L [12] denotes the active power distribution of generation output at bus i to the load situated at bus j [17].…”

“…The cost depends upon the magnitude, the path and the distance travelled by the transacted power. Various modified MW Mile methodologies have been proposed in the literature [10][11][12]. The first attempt to trace real and reactive power flow was done by Bialek et al when Topological Generation Distribution factors based Power flow tracing were proposed in March 1996 [13] which explained the method for tracing generators' output.…”

“…This paper presents a model of transmission usage allocation based on the concept of the modified matrices methodology [12] and transmission usage cost allocation is done based on rated capacity, and under contingency line outage impact factor (LOIF) [29] and proposed maximum line outage impact factor (MLOIF) is considered. Partial cost recovery is considered here.…”
