Research and application of secondary development using API of PSS/E

PSS/E is a power system simulation and analysis software commonly used by operational department, which is mostly applied to analyze single case based on artificial operation mode model. PSS/E application mode that API secondary development is used to simulate and control full physical model is proposed in this paper. Full model of power grid is automatically created based on CIM/E model file that exported from D5000, and the secondary development interface is used to calculate PSS/E flow and to achieve continuous process simulation for power grid. Data exchange to D5000 is obtained base on standard communication protocol. Key modules such as API secondary development, simulation model generation and simulation base on API interface in application process are described. Finally, actual simulation environment is set up using D5000 system of East China Power Grid, and the simulation results were verified.
