NDLI: Allocation of PMU channels at substations for topology processing and state estimation

Abstract	The new grid operation constraints, allied to the substation automation and intelligence, require the state estimation (SE) to work even more efficiently, with reliability and accuracy. The proposed method for optimally allocating existing phasor measurement unit (PMU) channels and their resources at substations ensures reliability in the SE process even in cases of equipment malfunctioning, and guarantees the quality improvement of the SE. The proposed algorithm has two stages. In the first stage, a genetic algorithm optimally allocates the PMUs. In the second stage, a heuristic method optimises measurement and channel allocation. Equipment failure, missing data, observability issues, methods to reduce critical sets in SE results to preserve the system's observability, are also discussed.
