Abstract: One application that is gaining attention in today’s deregulated market is the improvements that PMUs offer for real-time congestion management. Installing PMUs for full system observability is a large investment. The strategy used should be practical, adaptable, and cover the entire process from preparation to installation schedule. The three issues addressed in this paper placement model, placement algorithm, and simulation and result cover the entire process. The objective of optimal PMU placement problem is to install minimum PMU to ensure full observability of the power system. This paper deals with the decision tree algorithm for optimal placement of PMU for voltage security assessment.
