Impact of Energy Storage on Hybrid Ac-Dc Micro-grid During Pulse Load
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 generator 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 within 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 thereby improving the system reliability and stability.
