Implementation mode of tie-line power control performance assessment standard

This paper firstly analyzes the problems of the implementation modes of standard T. On this basis, the serial implementation mode of control performance standard (CPS) and standard T is put forward according to the thought of solving the main contradiction. The power system switches the CPS and standard T to solve the main contradiction in different operating states of ultra-high voltage (UHV) power grid. At the same time, four control modes are designed in consideration of UHV tie-line power deviation and system frequency deviation. Analyses and simulations have been made to prove that there will be no control contradiction between control areas with consideration of UHV tie-line power deviation and system frequency deviation in the serial implementation mode of CPS and standard T. ©, 2015 State Grid Electric Power Research Institute Press.
