Water supply control system for smarter electricity power usage adopting demand-response scheme

Demand-Response is a scheme in which electricity suppliers and consumers collaborate for smarter usage of electricity aiming to mitigate gap between supply and demand. It makes electricity consumers receive incentives through curtailing or increasing power demand during a certain period subject to the request from the power infrastructure. Water utilities, as heavy electricity consumers, could participate in the scheme through shifting power demand by modifying pumps operation schedule utilizing reservoirs’ buffering stock capability. We developed conveyance/transmission pumps scheduling algorithm to be applied in the scheme that requires quick modification of pumping schedule to respond the request. In addition, we made test bedding through simulation approach utilizing actual data of Osaka Water Supply Authority to show the scheme’s potential for waterworks and effectiveness of the algorithm. doi: 10.2166/ws.2019.143 s://iwaponline.com/ws/article-pdf/doi/10.2166/ws.2019.143/609662/ws2019143.pdf H.
