N2 - In power distribution systems, overcurrent relays (OC) are widely used for protection of the systems. The problem of overcurrent relay coordination in protection systems consists of selecting appropriate settings, satisfying the requirements of sensitivity, selectivity, reliability, and speed [1]. Existing optimum coordination methods usually assume conditions of fixed DG output and constant load in the distribution system, which is the static condition for the distribution system. When there is a variation of load or distributed generations in the distribution system, the above optimum coordination methods will fail to find the most desirable coordination of overcurrent relays under prevailing operating conditions. This paper proposes a novel solution for online adaptive coordination of overcurrent relays considering significant load variation and renewable generation variation for systems with increasing integration of renewable energy sources.
