Intelligent DE algorithm for measurement location and PSO for bus voltage estimation in power distribution system

Accurate monitoring and estimating the state of the distribution system poses an immense challenge to power engineering researchers because of bidirectional distribution system. This paper is executed in two stage methodology. The initial stage is to identify the optimal location for the installation of monitoring instrument with minimal investment cost through DE and PSO. The second stage is to estimate the bus voltage magnitude where real time measurement is measured through identified meter location which is more essential for decision making in DSCADA. The hybrid Intelligent technique is applied to execute the above two algorithms. The algorithms are tested with IEEE and TNEB benchmark systems.

► This study deals with intelligent estimation of bus voltage through optimal meter placement.
► The estimated voltage more accurate for monitoring and control of power distribution system.
► The meter investment cost tents to decrease through optimal number and location of meter.
► The algorithms utilized in this work are PSO, ANN and swarm tuned ANN.
