Book: Power Generation, Operation and Control 2nd Edition

You are given in the following network with meters at locations as shown in Figure 9.25. Four-bus system with measurements for Problem 9.3. Is this network observable? Set up the least-squares equations and try to invert [H^T R^-1 H]. Suppose we had a measurement of generation output at bus 3 and included it in our measurement set. Let this measurement be the following: M_3gen = 92 MW with sigma = 0.015 Repeat including this measurement.

Solution

a) this network is observable

inversion of above matrix gives 3

b) generation at bus 3

output will be 45
