APPROXIMATE CONTINGENCY ANALYSIS Contingency ranking • contingencies are ranked in an approximate order of a scalar performance index, PI. • contingencies are tested beginning with the most severe one and proceeding down to the less severe ones up to a threshold value. • Masking effect causes false orderings and misclassifications. Contingency screening • Explicit contingency screening is performed for all contingencies, following an approximate solution (DC load flow, one iteration load flow, linear distribution or sensitivity factors etc.) • Contingency screening is performed in the near vicinity of the outages (local solutions) Hybrid methods utilizing both the ranking and the screening
Security in Restructured Power Systems •In deregulated environment, System Operator (SO) is responsible for secure operation of the power system. •Available Transfer Capability is a term defined to reflect additional secure power transfer in the electricity market environment. •Congestion management is one of the major task performed by SO to ensure system security.
