XI LIN - PhD., P.Eng.
Director
Power Systems

Dr. Xi Lin is the Director of the Power Systems sector. His main responsibility is to develop and maintain the DSATools software package. DSATools provides a complete toolset for power system planning and operational studies. The key components in the suite, VSAT, TSAT, and SSAT, have also been designed to be used for on-line dynamic security assessment (DSA). In this mode, the software is connected directly to a power system’s energy management system (EMS) and assesses the system security in continuous cycles.
