AB - Significant changes in the power generation mix are posing new challenges for the balancing systems of the grid. Many of thesechallenges are in the secondary electricity grid regulation services and could be met through demand response (DR) services. Weexplore the opportunities for a water distribution system (WDS) to provide balancing services with demand response through pumpscheduling and evaluate the associated benefits. Using a benchmark network and demand response mechanisms available in theUK, these benefits are assessed in terms of reduced green house gas (GHG) emissions from the grid due to the displacement ofmore polluting power sources and additional revenues for water utilities. The optimal pump scheduling problem is formulated as amixed-integer optimization problem and solved using a branch and bound algorithm. This new formulation finds the optimal levelof power capacity to commit to the provision of demand response for a range of reserve energy provision and frequency responseschemes offered in the UK. For the first time we show that DR from WDS can offer financial benefits to WDS operators whileproviding response energy to the grid with less greenhouse gas emissions than competing reserve energy technologies. Using aMonte Carlo simulation based on data from 2014, we demonstrate that the cost of providing the storage energy is less than thefinancial compensation available for the equivalent energy supply. The GHG emissions from the demand response provision froma WDS are also shown to be smaller than those of contemporary competing technologies such as open cycle gas turbines. Thedemand response services considered vary in their response time and duration as well as commitment requirements. The financialviability of a demand response service committed continuously is shown to be strongly dependent on the utilisation of the pumpsand the electricity tariffs used by water utilities.
