A Direct Solution to Biobjective Partitioning Problem in Electric Power Networks

This letter presents a novel Laplacian spectrum-based approach to directly solve biobjective network partitioning problems. The proposed approach is applied to a typical power system partitioning problem in context of smart grids, where the resultant Pareto front considering two incompatible objectives can adaptively provide useful clustering information for a flexible and distributed system control. This approach has proven to be effective and computationally efficient through a case study of the IEEE 118-bus system.
