Making the power system intelligent

Abstract

The increasing power demand requires better exploitation of the existing system. A possible method is the decrease of the peak/valley ratio of the daily load curve. The intelligent applications help the control on the power system level. We dig in depth, how the intelligence of lower levels could be raised. The traditional ripple control can not be extended on a lot of programmable household appliances, as the washing machine, refrigerator, tumble drier, etc. We investigated typical households and found a great voluntary control potential. The paper presents the measurement results and gives a structure to take these loads into a “smooth” DSM.
