Autonomous Solar Photovoltaic/Battery System for the Electrification of Wastewater Pumping Stations

The wastewater treatment procedure generally requires pumping stations to allow the supply pipe to pass the topographical constraints of the site. Since these pumping stations are characterized by high energy consumption, and in parallel with the energy transition of our country, and national strategies for the integration of renewable energy systems, this paper presents an optimal sizing of an autonomous solar photovoltaic/battery system for supplying electricity to a wastewater pumping station. The Electric Systems Cascade Extended Analysis methodology, the LPSP as system reliability parameter, Life Cycle Cost, and Levelized Cost of Electricity are implemented together to obtain the optimal sizing of the proposed system. The hourly wastewater flow of the wastewater pumping station, the hourly solar irradiation of the site chosen for the case study, and the technical and economic data of the various components of the PV/Battery system are taken as inputs to the ESCEA method.
