Abstract
The liberalization of the electricity market induces a large variety of scenarios that may lead power systems close to their operation limits. This supports the need for on–line dynamic security assessment (DSA) of the grids, in order to provide operators with a clear insight of the current network state. The on–line application of DSA to a realistic network needs adequate methods to screen the large amount of contingencies to be examined by DSA tools. This paper proposes some practical heuristic indices for Transient Stability contingency pre–filtering and ranking in an on–line DSA session.File in questo prodotto:
