Differentiated Planning Model of Smart gird Considering Black-Start Power Sources

Improving the resilience of smart grid in disaster can reduce the loss and increase the speed of power restoration. In this paper, considering the function of black-start power source during system restoration and power supply for important loads, the differentiated planning model has been proposed to improve the resilience in smart grid. The proposed model aims to optimize both the cost of load-shed and enhancing generator investment, and the power operation constraints are involved. Taken the IEEE 14-bus and 118-bus system as examples for simulation, the simulation results demonstrate the feasibility of the model. The proposed model can ensure the power supply for important nodes and black-start power nodes, which can improve the resilience of power grid in disaster.
