Abstract
Renewable energy based distributed generation plays an important role in electricity production. Electricity is consumed at the same time as it is generated. In this paper ,a hybrid AC-DC micro-grid is considered in islanding mode with solar energy; energy storage is proposed for integration of a pulse load. A synchronous generated is used to connect to the AC side. The AC and DC sides are linked through a bidirectional AC-DC inverter in order to control the power flow between AC and DC sides of the system. When a pulsed load is connected or disconnected on the AC side , the AC side voltage and frequency are maintained with in limits by the support of energy storage on DC . Simulation results show that the proposed micro-grid with control algorithms has maintained a balanced current and voltage profile there by improving the system reliability and stability.
