| Research Abstract |
Consumers will change the use of their appliances in order to maximize their benefits obtained from electricity consumption when information about electricity price and power quality is given by electricity suppliers. This consumer's behavior is called demand response. The purpose of my study is to clarify how demand response affects stability of electric power systems. In the study, basic characteristics of the demand response were identified through questionnaire and experiment using a power system simulator. It was also clarified that time delay with direct appliance control for reducing frequency and voltage fluctuations could cause instability of power systems. The results of the study are useful for stable operation of future electric power systems with advanced demand side management systems.
