Electrical power systems are undergoing a major change globally. Ever increasing penetration of volatile renewable energy is making the balancing of electricity generation and consumption challenging, forcing transmission system operators to spend increasing amounts of money for ancillary services. This creates interesting opportunities for demand side assets, that would be able to adjust their power...
Deregulated electricity markets with time varying electricity prices and opportunities for consumer cost mitigation makes energy storage such as a battery an attractive proposition; users can charge the battery when prices are low and discharge the battery for activities when prices are high. An electricity storage system with enough capacity to support hours of home use can be expensive for an individual...
Demand response systems in the electricity grid, which rely on two way communication between the consumers and utility, require the transmission of instantaneous energy consumption to utilities. Perfect knowledge of a user’s power consumption profile by a utility is a violation of privacy and can be detrimental to the successful implementation of demand response systems. It has been shown that an...
Dynamic pricing constitutes a promising approach for realizing the significant potential of flexible demand. However, naïve application of dynamic pricing leads to demand response concentration at the lowest-priced periods, yielding significant new demand peaks and inefficient system operation. A previously proposed measure imposing a flexibility restriction on flexible loads may not be acceptable...
Widespread renewable energy resources cause short-term supply-demand imbalance. It is desirable to use Demand Response (DR) for solving balancing problem. Controlling consumers' energy storages (ES) is promising in this regard. However, consumer's ES based DR for short-term supply-demand imbalance suffers from reliability problems caused by both, unexpected state of charge (SoC) saturation/depletion...
