Power system stability standardization under present-day conditions

Russian and foreign conceptions of power system stability standardization are considered. A necessity to revise the actual power system stability regulations fundamentals under current economic and network conditions of the Unified Power System of Russia (the UPS of Russia) is founded. Special attention is given to evaluation of required steady-state stability margins under normal and post-fault conditions of power system operation. The results of computer simulations intended for comparison of required transient and steady-state stability margins in the Russian Far East Interconnected Power System model are presented. Conclusions regarding the possible ways of power system stability regulations improvement based on the typological transmission systems structures are made.
