The DICE project has developed and demonstrated smart control capabilities for electric water heating systems, one of the most commonly used white goods in Europe. An open technology was created which fosters the notion of reusable software and hardware components in embedded systems. Key technology includes smart control capabilities using fuzzy logic components and communicating capabilities based on the European Home Systems (EHS) power-line emerging technology. DICE has focused on several electronic profiles: stand-alone profiles; profiles with EHS communication capability; profiles with hardware fuzzy logic support for smart control support. Two controllers have been developed and tested. The first used in UK is based on four temperature sensors. The second used in France is based on one temperature sensor and one flow meter sensor. They demonstrated: the use of European Home Systems (EHS) communications technologies to provide control of domestic water heating; that the use of electric immersion heaters is optimized with respect to cost reflective messages (CRM) in order to provide Demand Side Management (DSM) services for the utility and minimizes costs for the customer. Development focused on reusable software and hardware components suitable for water heating control: at the application level. A specific control algorithm was developed for the French heater (handling 1 temperature sensor and France-specific CRM messages). Two variants were developed, one using the WARP fuzzy logic technology (rule programming), and one using the 8051 controller: at the EHS communication level; a medium access control (MAC) layer component was developed. A software level for the development of advanced components technology. Its effect is to drastically reduce the central processing unit (CPU constraints for the handling of bit processing in the software library. The EHS library (EHSLib) was adapted to a real-time kernel. The kernel runs on the 8051 micro-controller.
A water heating controller has been developed which optimizes the heating of water to take account of British specific half hourly electricity prices. It uses 48 half hour slots, each of which can have a different price, set by the electricity company via a communications gateway (power line, telephone or radio telemeter). There are also significant cost and comfort benefits for the user. The DICE UK water heating controller makes use of a backwards charging algorithm and user set-points. Taken together, these factors reduce the peak load compared to a normal radio telemeter control as both the distribution of user set-points and the distribution of charging requirements will have a 'smearing effect' on the load profile. Two types of controller have been developed and trialed within the UK. There is a communicating version which receives time and cost messages from a central controller via the power-line, thus reducing the problems of wiring during system installation, and there is a stand-alone version which is pre-programmed with an electricity company's preferred tariff.
