摘要
A new technique for constructing the dynamic equivalents for power systems is developed. The technique utilizes a balanced state-space representation to determine the order, state matrix, and either the input matrix or the output matrix of the reduced-order model. The other matrix is found such that the reduced-order model matches the full-order model at both high and low frequencies. The suitability of the new technique for obtaining reduced-order models for the dynamic control of a power plant is demonstrated on a single-machine infinite-bus system.
