HEURISTIC BASED OPTIMAL PMU ROUTING IN KPTCL POWER GRID

Power system monitoring is an important process in an efficient smart grid. The control centers used in smart grid requires restructuring. State measurements rather than state estimationare pre-requisite for the modern control center. The Phasor Measurement Unit (PMU) measures the synchronized voltage and current parameters. Placement of minimum number of PMUs in a bus system such that the wholes system becomes observable is considered as Optimal PMU Placement (OPP) problem. In this paper, Hybrid Distance Optimization (HDO) algorithm is proposed to reduce the number of PMUs for complete observability along with the minimum length of fiber optic cable required for interconnecting the PMU nodes. Since Fiber optic is invariably used for communication of PMU data, shortest distance for interconnecting PMU nodes will result in minimum cost for creating an efficient communication infrastructure, thereby reducing the cost for establishing Wide Area Monitoring System (WAMS). The HDO algorithm combines the three algorithms.
