In this paper, we challenge this premise by proposing a much more active role for intelligent loads specifically related to frequency control and dynamic stability. In modern systems the load is typically only controlled under severe stability conditions via load shedding. Recent research has demonstrated that many loads could cost-effectively become intelligent, allowing for the potential of the loads to more actively participate in system operation and control. The potential benefits of active load control are investigated. Also, reliability and implementation issues are explored.

Fast rising transients that reach the transformer can cause large turn-to-turn voltages at the line end of the windings and resonances, which result in large voltages to ground elsewhere in the windings, many of which may exceed the winding insulation strength. Field experience indicates that resistor-capacitor devices are effective in preventing switching induced insulation failures by introducing significant damping into the circuit. Since shielded underground cable has the ability to absorb high frequency energy, it may be able to provide similar protection to transformers. During this investigation, impulse and switching tests were performed on representative EPR and TR-XLPE insulated cables connected to distribution transformers. This analysis was directed toward quantifying the attenuation characteristics of different types of cables vis-a-vis fast fronted lightning impulse and switching induced breaker re-ignition transients. The conclusions of this report point to an economical way for protecting transformers from fast fronted voltage transients","PeriodicalId":123024,"journal":{"name":"2005/2006 IEEE/PES Transmission and Distribution Conference and Exhibition","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121648559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
