Energy Management System for Small Scale Hybrid Wind Solar Battery Based Microgrid [PDF]

E3S Web of Conferences, 2023
In recent years, the power system has been evolved into micro grids, which are little pockets of self-contained entities. Different distributed, interconnected generation units, loads, and energy storage units make up a typical microgrid system.

Robust estimation based nonlinear higher order sliding mode control strategies for PMSG-WECS [PDF]

Bulletin of the Polish Academy of Sciences: Technical Sciences, 2023
The wind energy conversion systems (WECS) suffer from an intermittent nature of source (wind) and the resulting disparity between power generation and electricity demand. Thus, WECS are required to be operated at maximum power point (MPP).

Investigation on PTO control of a Combined Axisymmetric Buoy-WEC(CAB-WEC) [PDF]

Ocean Engineering, 2019
The Combined Axisymmetric Buoy (CAB), a vertical axisymmetric buoy, has the potential to deliver a high energy absorption power. Considering the CAB-Wave Energy Converters (WEC), in order to achieve higher efficiency, the Power Take Off (PTO) systems, which converts the float motion into energy output, needs to be properly controlled.
