Utilization of DSM and smart grids, to control load rather than generations, is explored. Usually, system security is attained through preventive measures, the system is maintained and prepared in advance to survive credible outages through ＂reserve management＂, for which requirements are specified as security standards in grid codes. However, with the utilization of DSM techniques on transmission level such as ＂direct control load＂, ＂responsive load＂, and interruptible load control, system operations can be shifted towards ＂corrective＂ mode keeping intact the system security.展开更多
