Creating Active and Reactive Power Reserve Zones for Large-Scale Electric Grids

This paper proposes a strategy to partition large electrical grids into active power and reactive power reserve zones by applying a clustering algorithm to the Laplacian of the power system Jacobian matrix. This strategy is applied to two large synthetic cases with around 7k and 24k buses, and the results are provided. This partitioning further facilitates determining each zone’s required real power and reactive power reserve types.
