Enrique Castillo, Antonio J. Conejo, Rosa Eva Pruneda, Cristina Solares · IEEE Transactions on Power Systems · 2005
This letter describes a new technique for state estimation observability analysis. This technique is computationally efficient and based on calculating the null space of the measurement Jacobian matrix. The technique is illustrated through a clarifying example. Conclusions are duly drawn.
