Smart Distribution Grid

Self-healing is an important feature of smart distribution grid. Self-healing control for smart distribution grid covers risk prevention and operation optimization before accidents, in addition, it covers fault location, fault isolation and power restoration. The research of self-healing control theory, risk assessment, fault diagnosis and safety warning for smart distribution grid provides technical supports to help build a safe, reliable, efficient, high-quality, flexible and compliant smart distribution grid.

Intelligent Planning

The wind-solar-storage and other distributed generation (DG) accessing to the distribution grid and user’s interaction with the grid change the business’s forms of the traditional distribute and utilize system, and while the supplier and demander of electric power also set higher requirements on business’s functions of the smart distribution and utilization system. Based on business requirement of smart distribution and utilization, the major content and function of distribution and utilization link are discussed, including intelligent planning, intelligent dispatching, self-healing control, demand side management, two-way interaction and so on. It makes the architectures of business and the objectives of construction more clear and promotes the construction of the business system in the smart distribution and utilization system.

The Impact

Self-healing is the ability of a distribution system to automatically restore power after permanent faults. This paper investigates the impact of outages in the distribution network elements following the occurrence of a fault. The work aims to restore maximum available power to consumers in the affected areas, after the isolation of faulted parts, by optimal procedure of switching operations. In this work, CYMDIST software was used for the simulation and analyses of a distribution network in Samawa City. MATLAB 2017b/Simulink was used to implement self-healing, through the simulation of smart protection system that is controlled remotely by a central control unit. The results of implementing the proposed self-healing system on Samawa a New 11 kV network show a maximum power restoration with a minimum number of switching operations that have been achieved after fault isolation without violating constraints.
