 The paper discusses two methods of reducing energy consumption in water distribution networks, hydraulic regulation, HR, and electrical regulation, ER. HR involves using a pump as a turbine to generate electricity while ER uses an inverter to convert mechanical energy into electrical energy. The paper compares the two methods and finds that HR is more efficient and flexible than ER. Additionally, it shows that HR is more economically viable than ER. This article was authored by Helena M.
