Proper meter placement is necessary to accurately measure the values of electrical parameters which is important for automatic management and control of complex power distribution networks. This paper presents a new algorithm of optimal meter placement for power system state estimation, (SE) which would minimize the total investment cost subject to a constraint of state estimation accuracy. The problem solution is based on Particle Swarm Optimization (PSO) algorithm and reflects the cost of individual meter installation and its contribution to the state estimation accuracy in the probabilistic sense. The next stage of the work is monitoring the distribution system by proper placement of meter at specified location. The algorithm is tested with IEEE 37 node system and Tamil Nadu Electricity Board (TNEB) 12 node distribution system.
