The necessity for grid codes of the dispersed wind power connected to power grid is described briefly and the definition of the dispersed wind power is discussed compared with the distributed wind power in China. Aimed at the dispersed wind power, the main technology indicators of wind power grid codes between Denmark (below 100kV), Germany (below 60kV) and China in aspects of access principle, connection mode, active power / frequency control, reactive power / voltage control, fault ride through and power quality are compared to provide reference for the modification and completion of the dispersed wind power grid code in China.

Stability Control System

There is a need to build power grid on RTDS in order to testing performance of security and stability equipment (SASE). The paper divide a large-scale province power grid into four region grid with present RTDS hardware capacity in a view to include all stations installing SASE in a single region grid and disconnect lines as few as possible between adjacent region grids. The paper gives method of manually calculating and modeling node’s power balance, keys of building region grid and matters needing attention transforming parameter format from BPA to RTDS, and then simulating results show that steady state error of some variables are less than one percent, all less than 10 percent and transient characteristics help SASE to start-up to some extent.
