Sustainability from the Occurrence of Critical Dynamic Power System Blackout Determined by Using the Stochastic Event Tree Technique

Abstract

Abstract:With the advent of advanced technology in smart grid, the implementation of renewable energy in a stressed and complicated power system operation, aggravated by a competitive electricity market and critical system contingencies, this will inflict higher probabilities of the occurrence of a severe dynamic power system blackout. This paper presents the proposed stochastic event tree technique used to assess the sustainability against the occurrence of dynamic power system blackout emanating from implication of critical system contingencies such as the rapid increase in total loading condition and sensitive initial transmission line tripping. An extensive analysis of dynamic power system blackout has been carried out in a case study of the following power systems: IEEE RTS-79 and IEEE RTS-96. The findings have shown that the total loading conditions and sensitive transmission lines need to be given full attention by the utility to prevent the occurrence of dynamic power system blackout.

A Case Study on National Electricity Blackout of Turkey

“…Despite this regulation, many power plants disabled themselves or switched to the island mode. As a result, electricity service was interrupted from the east to west parts of Turkey and the NEN of Turkey had lost its synchronization with the ENTSO-E system [53][54][55][56][57]. After a second, the interconnection of Turkey with Bulgaria and Greece was lost.…”
