BTNRAS, A tool for Transmission Network Risk Assessment

With deregulation of power system market, the uncertainties in modern power system increase, risk assessment has become an effective tool for power system analysis considering the uncertainties. A software named as BTNRAS (Bulk Transmission Network Risk Assessment System) is presented in this paper. Besides quantitative risk evaluation indices, BTNRAS provides some auxiliary functions, such as risk results visualization, sensitivity analysis, weak point identification and comparison of planning schemes, which can provide some beneficial references to power system planners and operators. Based on object oriented design, the calculation program of BTNRAS is developed by visual c++, while a graphical user interface is developed by QT software package. Finally correctness and effectiveness of BTNRAS are validated by some actual power systems.
