摘要：
With the stochastic power fluctuation occurring on the ultra-high voltage (UHV) AC tie-line of North China power grid and Central China power grid, a control performance index, namely the multi-zone tie-line index (MT index) is proposed. The index is a combination of the basic ideas of both NERC's control performance standard (CPS) and standard T. This index focuses on the automatic generation control (AGC) of UHV tie-lines of interconnected power grids. It can be used to evaluate the subarea's contribution (e.g. provincial power grids) to the control of power fluctuation on the main tie-line in a large power grid. Based on this, an AGC controller for suppressing the power fluctuation on main tie-lines is designed. Simulation results show that controllers designed under MT index can be used to suppress the power fluctuation on main tie-lines efficiently. ©2013 State Grid Electric Power Research Institute Press.
