Artificial Intelligence Versus Conventional Mathematical Techniques: A Review for Optimal Placement of Phasor Measurement Units
2016
Technology and Economics of Smart Grids and Sustainable Energy
Preserved Fulltext
It is necessary to determine the minimum number of PMUs for entire observability of the power network. The optimal placement of PMUs (OPP) problem can be solved by various techniques. ...
This implies that a system can be made observable with a lesser number of PMUs than the number of busses. ...
In recent years rapidly increases use of PMUs to improve monitoring, needed to place these PMUs on all of the buses for full observability of the network. ...

This paper presents a new procedure for finding the optimal placement of the phasor measurement units (PMUs) in modern power grids to achieve full network observability under normal operating conditions ...
The results show that full network observability can be met under normal conditions using 20% PMUs penetration; however, under contingencies, approximately 50% PMUs penetration is required. ...
PMU placement at all buses would permit direct measurement of the network state. ...
