The advent and wide spread utilisation of power sensitive electronic equipment in the industrial, commercial and residential sectors has brought significant attention to the importance of power quality. Voltage related power quality disturbances such as voltage dip and voltage swell are the most commonly occurrences in a typical power system. Voltage dip and voltage swell can lead to failure or malfunction of critical equipment leading to both operation and financial loss for the customer. Both voltage dip and voltage swell cannot be eliminated from the power system since system faults, weather and disturbances are stochastic in nature. However, they can be mitigated. The existing power system was not designed to accommodate renewable energy sources. With recent environmental concerns and fluctuating oil prices, it results in high degree penetration of renewable energy sources into the power system, which has made power system more complex and vulnerable to power quality disturbances. This report dissertation review voltage dip mitigation method with comparison of various types of energy storages which are suitable to be implemented in order to enhance the reliability of existing power system.
