An extensible PSS/E power flow calculation method based on CIM/E full model is proposed. By using hierarchical network model database as interlayer, CIM/E model is parsed into the interlayer database and the synchronized PSS/E calculation database is generated simultaneously, and full physical model of power grid is built automatically. Interface layer is built based on API secondary development and packaging, and power flow calculation is run automatically and periodically by flow control of PSS/E through external application. By using hierarchical network model database as input and output interface to receive and process device operational order from external appli
