the talk addresses several key problems for reliable and efficient modeling and monitoring of smart grids. in term of model calibration, a new framework for identification and correction of model parameter errors is presented. the largest normalized lagrange multiplier (lnlm) test is introduced, and approaches for enhancing the reliability and computational efficiency of model error identification are presented. in terms of system monitoring, a unified robust state estimation approach against measurement and parameter errors is introduced. a fast and parallel implementation of bad data processing methods is also presented. finally, the cyber-security issues in the modeling of smart grids are discussed. a security vulnerability regarding model databases which may affect the operation of electricity markets is identified, and possible countermeasures are discussed.
