 The paper discusses two methods of managing water distribution networks, hydraulic regulation, HR, and electrical regulation, ER. HR uses a series parallel hydraulic circuit with a pump as a turbine, PAT, to generate electricity while ER uses an inverter to convert mechanical energy into electricity. 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.
