Application of dynamic zoning scheme in Guangdong power grid

In this paper, power system area division scheme is discussed for system operation and control. By using system sensitivity analysis and N-1 contingency analysis, a dynamic system zoning scheme is proposed. Applying this area division scheme can reduce the risk of system mis-operation due to the complexity of power system and simplify the computing process. The proposed dynamic zoning scheme has been verified and tested using the network of actual power system of Guangdong province, China. And this scheme will be eventually applied as a build-in module in the next generation EMS system design for Guangdong power grid.
