A quick and practicable power flow tracing method on electric energy market. II. A new practicable method

For pt.I see ibid., vol.2, p.1244-9 (2001). Based on the theoretical proof in part I, a proportional sharing principle is incorporated with the load-flow tracing method for solving practical problems, such as the allocation of network loss, etc. Part II first analyzes the theoretical background of load-flow tracing, then advances sequences of load-flow tracings (downstream and upstream tracings), and calculates the contributing factor (of generators) and deriving factor (of loads). By applying the method to an IEEE 14-bus sample network computation, not only can this method be used to analyze the relations of load flow in the actual system, it can also well and truly reflect the nonlinearity of this problem since it is based on alternating current circuit theory.
