ADAPTIVE PROTECTION SCHEME FOR ISLANDED MODE OF OPERATION
DESIGN DETAILS The conventional means of electric energy production have been recently considered to be replaced by renewable resources due to the increasing concerns of environmental degradation, depletion of fossil fuels, increasing fossil fuel prices, etc. Accordingly increasing renewable energy penetration and new types of loads, such as electric vehicles, have necessitated the adoption of smart solutions by the electricity industry. To enable the local utilization of the energy produced and to defer the need of new investments in power delivery systems, distributed generation (DG) units are considered a promising solution within the smart grid vision. However, the presence of DG, especially in distribution systems, is likely to be associated with some drawbacks, as well. The integration of DG units increases the complexity in the operation, control, and protection of medium and low voltage power systems. The power flow in the distribution system is unidirectional when DG is not connected. However, the power flow becomes bi-directional in many sections of the distribution system, and as a result, conventional protection schemes considering just one-way power flow become insufficient. In this Matlab design, an protection strategy is applied for a distribution system by creating fault in the bus system and then applying adaptive protection scheme based on adaptive overcurrent to find TMS and Tripping Time.The strategy considers islanded mode of operation, while the adaptive operation of the protection is dynamically realized considering the availability of DG power production (related to faults or meteorological conditions) in each time step. The system detects any changes in the configuration and recalculates the protection settings by using an optimal coordination DOCR by applying micro-genetic algorithm. Besides, the modular structure and fast response of the proposed strategy is validated via simulations conducted on the IEEE 13-node test system using Matlab 2020a version.
