Strategy of energy control in PVP/battery water pumping system

Pumped storage is generally viewed as the most promising technology to increase renewable energy source penetration levels in power systems and particularly in small autonomous systems. Combined battery and pump constitute a realistic and feasible option to achieve high penetrations. This paper focuses on dynamic modeling, simulation, control and energy management in an isolated integrated power generation system consisting of a 2 kW PV and 100 Ah lead acid battery storage. A supervisory controller is designed for energy management between the maximum energy captured from the PV and consumed energies of the load. Dynamic modeling and simulation are fulfilled using MATLAB Simulink™7.2.
