Design and Implementation of a Control Strategy for Microgrid Containing Renewable Energy Generations and Electric Vehicles

الملخص EN

Large amount of such renewable energy generations as wind/photovoltaic generations directly connected to grid acting as distributed generations will cause control, protection, security, and safety problems.

Microgrid, which has advantages in usage and control of distributed generations, is a promising approach to coordinate the conflict between distributed generations and the grid.

Regarded as mobile power storages, batteries of electric vehicles can depress the fluctuation of power through the point of common coupling of microgrid.

This paper presents a control strategy for microgrid containing renewable energy generations and electric vehicles.

The control strategy uses current control for renewable energy generations under parallel-to-grid mode, and uses master-slave control under islanding mode.

Simulations and laboratory experiments prove that the control strategy works well for microgrid containing renewable energy generations and electric vehicles and provides maximum power output of renewable energy and a stable and sustainable running under islanding mode.
