Optimization methods to solve the set covering problems

Phasor Measurement Unit Placement aims to decrease the cost this phasor equipment while maintaining observability of electrical distribution systems. This placement can be modeled as a set covering problem. Synchronized data provides systems’ information with higher quality and frequency than Remote Terminal Units. These enable implementation faster real-time state estimators. Thus, supervisory control acquisition systems replaced by automatically monitored that add reliability, efficiency, resilience smart grid Due flexibility large-scale in systems, heuristic methods have frequently been applied Since use Chemical Reaction Optimization (CRO) algorithm is not recurrent, we decided implement it together topological system analysis. Initial population creation, parameterization, elementary reactions CRO, local search strategies are presented study. Computational results were performed IEEE power test cases. The optimization method proposed has obtained optimal at lower computation time literature. To large-scale, another Set Covering Problems from Beasley library, different parameters. However, satisfactory indicating CRO might suitable some instances library. In case, further studies required.
