Abstract
Traditional electric distribution systems are radial in nature. These networks are protected by very simple protection devices such as over-current relays, fuses, and reclosers. Recent trends in distributed generation (DG) and its useful advantages perfectly can be achieved while the relevant concerns are deliberately taken into account. For example, penetration of DG disturbs the radial nature of traditional distribution networks. Therefore, protection coordination will be changed in some cases, and in some other cases it will be lost which is very costly in that two cases. In developed countries it could be cost effective if adding DGs 
network keeping the traditional protection system unchanged. To tackle that point of research, authors proposed technique to maintain the old protective devices coordination unchanged up to a specific DG penetration level. 
In this paper, a framework is presented for determining the maximum capacity of DG penetration level to keep traditional protection scheme for distribution network unchanged. Applying that framework in the developing countries could save money and time during the integration of DGs to the network on a large scale based on country regulation. The proposed framework is implemented on a simple distribution network using MATLAB SIMULINK and finally the numerical results are presented in order to validate the suggested framework.
