The advent of power quality sensitive equipment has made the provision of good power quality a real challenge across the globe. With the increasing usage of sophisticated sensitive electronic equipment in industrial, residential and commercial sectors, it is important to protect them from any power quality disturbance in order to avoid equipment damage and malfunction leading to financial loss for the customer. Voltage quality disturbances such as voltage dips pose a serious concern as a power quality problem, since due to their stochastic nature they cannot readily be eliminated from regular utility systems. However, they can be mitigated. High degree of penetration of distributed generation in power networks is useful in delivering different benefits to the utility in the form of ancillary services one of which is voltage dip mitigation in case of system contingencies. This paper presents a comprehensive review and comparison of various distributed generation schemes used by utilities for mitigation of voltage dips in power networks.
