A generalized power transfer distribution factor for power injection analysis of power grids

A generalized power flow sensitivity index is proposed based on the traditional power flow distribution sensitivity analysis method. A strategy for power injection and power flow allocation is proposed, concerning the background of integrating the renewable energy resources into the traditional power grids. A coordinated operation mechanism between the injected renewable energy resources and the existing power generators is proposed. The reliability of the power grids can be improved. The power flow on the distribution network can be reduced. Simulation study verifies the claims in this paper.
