Parallel and distributed state estimation [PDF]
IEEE Transactions on Power Systems, 1995 The need for higher frequency in state estimation execution covering larger supervised networks has led to the investigation of faster and numerically more stable state estimation algorithms. However, technical developments in distributed Energy Management Systems, based on fast data communication networks, open up the possibility of parallel or ...
