摘要：The current power system is working under sustaining energy shortages. The distributed generation (DG)can be a solution for the energy shortage. Distributed generation refers to generation of power using a set of small sizedgenerators that produces power at low voltage levels. The distributed generators are mainly designed to be connecteddirectly to the distribution network near load centres. The distributed generation have some negative impacts in thepower grid. Many of the DG sources like wind, solar etc are intermittent in nature. The source impedance is varying innature due to these intermittencies. The fault current characteristics are changing in the presence of distributedgeneration. Existing relay settings will not sense these change, which leads to malperation of relays. The adaptiverelaying can be a solution for the malfunction of relays. Adaptive relaying means the relay has to adapt to the changingenvironment. The decision making capability is to be incorporated with existing relays. The impact of increment of DGpenetration in Kerala power grid is studied and adaptive relaying is suggested as the solution strategy.
