Identification of wheeling paths by an extended sensitivity analysis

Abstract

-This paper proposes a practical method for identifying wheeling paths in deregulated electricity markets based on an extended sensitivity analysis. Using this method, it becomes possible to fix the proper and fair wheeling rate according to the degree of responsibility of each power flow transaction. Moreover, a wheeling rate based on the real power flow responsibility is also an important signal to new power suppliers in the markets. In order to show the validity of the proposed method, a series of simulations on the IEEE 30 bus test system were conducted.

Wheeling Charge Reflecting the Transmission Conditions based on the Embedded Cost Method

“…Therefore, in the previous paper [6], we have reported an efficient method for identifying wheeling paths based on an extended sensitivity analysis to relieve the above problem. Moreover, we have reported the method of setting the wheeling charge reflecting the transmission uses better than (3) by extending the conventional MW-mile method [2].…”

“…In this section, we will identify the wheeling paths for the example described in Section 3.1 by using the extended sensitivity method that we have reported [6]. Here, the wheeling between node 14 and node 18 is dealt as an example.…”

“…In this section the wheeling charge is calculated for four wheelings assumed in Section 3.1 by the postage stamp method which is performed in the Japanese electricity market and the proposed methods expressed in (4)- (6). By the way, parameter like transmission capacity is set based on [7], [8].…”

Sensitivity Analysis of Stability Problems of Steel Structures using Shell Finite Elements and Nonlinear Computation Methods

“…Within the scope of modelling, the notion "sensitivity analysis" has different meaning to different people, see, e.g., [27][28][29][30][31][32][33][34][35][36][37][38][39][40]. Other examples as to why we carry out the sensitivity analysis are listed in [26].…”
