Generalized distance-based protection design for DG integrated MV radial distribution networks — Part I: Guidelines

•Guidelines for distance protection design in MV radial feeders with DG are proposed.•DG infeed, fault resistance and other influencing factors are addressed.•Coordination of distance protection with lateral protection is addressed.•Economic feasibility of the designed protection scheme is taken into account.•Existing distance relay technology is used to enhance the scheme’s applicability.
