Microgrid modeling and power quality enhancements using low-level control methods based on robust RST controller
Résumé
The electric grids are in constant mutation and are heading towards more smartness to ensure different objectives such as: better integration of renewable energy (RnE), balance management for supply and demand, reduction of greenhouse gases (GHG), power quality enhancement, security of energy supply for the consumer. This paper purposes is to illustrate the role of a robust low-level control in term of power quality enhancement of micro-grid based on photovoltaic source and battery storage system. The concept of smart microgrid (MG) is firstly discussed, and then the studied MG elements are modeled. A centralized control scheme is presented and the controller design is detailed. A robust RST controller is proposed where its effectiveness is compared to a classical PI controller through simulations tests.
