Isolation and restoration procedures of distribution system based on partial restricted substation capacity / Muhammad Sofar Yahya

The management of electricity distribution has to cope with rapid changes in the business environment, due to the liberalization in the electrical energy market. This will cause difficult for modelling the power system during the restoration process following the major outage. The modeling power system has three stages: 1) Generation 2) Transmission 3) Distribution. This paper is discussed the impact of distribution system capacity on load point reliability and the cost of load point interruptions. They also talk about why we use the isolator compared the circuit breaker. The main goals is maximizes the amount of load that can be restored after a grid blackout, substation outage, and distribution feeder line section outages. The outage in the system can give impact to the cost of the maintenance. The case study in this paper discusses about the when the fault occurs in the system, some of the load is transferred to another substation.
