“…Transient stability analysis using SIME, where the system is transformed into an OMIB equivalent, is very well covered in the literature [18][19][20][21][22][23][24]. The SIME approach transforms a 80 multi-machine system to an OMIB equivalent, based on the fact that a loss of synchronism originates from the separation of one machine against another machine (or groups of machines).…”

The paper presents a decision support tool for transient stability preventive control contributing to increased situation awareness of control room operators by providing additional information about the state of the power system in terms of transient stability. A timedomain approach is used to assess the transient stability for potentially critical faults. Potential critical fault locations are identified by a critical bus screening through analysis of pre-disturbance steady-state conditions. The identified buses are subject to a fast critical contingency screening determining the actual critical contingencies/buses. These two screenings aim at reducing the computational burden of the assessment, since only contingencies considered as critical are taken into account. The critical clearing times for the critical contingencies are determined. A preventive re-dispatch of generators to ensure a predefined minimum critical clearing time for faults at all buses is proposed, while costs are minimized. The results of the assessment are presented to the control room operator, who decides to accept the suggested dispatch or to repeat the assessment considering additional user-specific constraints. The effectiveness of the proposed method is demonstrated on a standard nine-bus and the New England test system.

“…The latter aimed at developing an on-line platform for dynamic security assessment, training simulation and market simulation. The overall project is presented in [6], whereas transient stability assessment results, as well as VSA tests on another system are reported in [7]. This paper focuses on long-term voltage stability driven by load restoration through tap changers, overexcitation limiters, switched compensation and possibly secondary voltage control [1,8].…”

This paper describes the on-line Voltage Security Assessment methods implemented at the national control center of the Hellenic Interconnected System, within the framework of the OMASES project funded by the European Union. The heart of all computations is a fast time-domain method. Security is analysed with respect to power transfers in critical corridors or power consumption in load areas. Results take on the form of either pre-contingency secure operation limits, or post-contingency loadability limits, together with various diagnosis tips. Contingency filtering is performed to meet the real-time requirement. Typical results obtained during the test phase of the project are reported.

Abstract-This paper describes the on-line Voltage Security Assessment environment developed within the framework of the EU-sponsored OMASES project, as well as its application to the Greek Interconnected Power System. The heart of all computations is a fast time-domain method. Security is analyzed with respect to power transfers in critical corridors or power consumption in load areas. Results take on the form of either precontingency secure operation limits, or post-contingency loadability limits, together with various diagnosis tips. Typical results obtained during the test phase of the project are reported.
