This paper studies on establishing the mathematical optimization formulation to coordinate the operating times of directional overcurrent relays in transmission networks. The objective function of this optimization formulation is to minimize the total operation time of all directional overcurrent relays, and it must satisfy the highly nonlinear constraints such as the time multiplier setting range, the plug setting range, and the coordination time interval between the primary and backup relay pair.

This paper uses the discrete element method to simulate a soft grain that can deformed without rupturing. This soft grain is composed of rigid primary particles with a cohesive contact law between them. The results showed that rigid primary particles within the deformable grain can move and rearrange in response to vertical compression.
