Optimal Allocation Scheme of “Source-load-storage” Distributed Resources in Distribution Network for Supporting Black Start of Key Nodes in the Main Network

Abstract

To fully exploit the potential and value of “source-load-storage” multi-type distributed resources to support blackouts at key nodes of the main network, we propose an optimization model for the optimal allocation of distributed resources. First, a black-start power configuration model with optimal operational economy and the strongest black-start capability is established as the optimization objectives. Subsequently, a simulation analysis is conducted with the IEEE33 node system and the regional grid of the Shanghai Fengxian combustion turbine plant as examples. The results indicate that the proposed model can realize the solution of the optimal black-start resource allocation scheme, which is applicable to black-start planning under multiple types of outage scenarios. Moreover, it provides a basis for using distributed resources to support the black start of key nodes in the main network.
