Abstract

The micro-grid that is composed of wind and solar power has wide prospects. Micro-grid has two kinds of operation mode that is grid-connected operation and independent operation. Unreasonable switching control will produce assault current that impact micro-grid operation. The smooth switching between two modes is needed to ensure the continuity of the load power supply. The control strategy of the grid-connected operation and the independent operation are studied in this thesis, and a control method base on fuzzy PID is proposed. Simulation research is done under the MATLAB/Simulink. The result shows suggested control method can make micro-grid seamless switching between independent operation and grid-connected operation.
