Abstract
A new method for Power System State Estimation (PSSE), the 'Path Method', is developed and studied. In this method the state (voltage magnitude and angle) of one node is calculated at a time, using only the local measurements. This procedure is repeated to calculate the state of all nodes in the system, following a predefined path to determine the next node whose state is to be calculated. In the process, more measurements are used whenever available and possible. Results obtained for this method are comparable and close to those of the Line-Flow Only (LFO) method. An advantage of the Path method over the LFO method is the speed of execution. Also, an algorithm to detect those lines with bad data (z.e. measurements with gross errors) is developed and tested. It is concluded that the algorithm can detect the lines with bad data successfully.
