REAL TIME MONITORING OF RADIAL DISTRIBUTION SYSTEM THROUGH OPTIMAL PSO METER LOCATION

摘要

Proper meter placement is necessary to accuratelyrnmeasure the values of electrical parameters which isrnimportant for automatic management and control ofrncomplex power distribution networks. This paper presentsrna new algorithm of optimal meter placement for powerrnsystem state estimation, (SE) which would minimize therntotal investment cost subject to a constraint of staternestimation accuracy. The problem solution is based onrnParticle Swarm Optimization (PSO) algorithm andrnreflects the cost of individual meter installation and itsrncontribution to the state estimation accuracy in thernprobabilistic sense. The next stage of the work isrnmonitoring the distribution system by proper placement ofrnmeter at specified location. The algorithm is tested withrnIEEE 37 node system and Tamil Nadu Electricity Boardrn(TNEB) 12 node distribution system.
