Urban Power Grid Structure Considering the N-1-1 Outage Standard
Urban power grid is a major load center of power system.The power supply capacity in N-1-1 outage is the important part of the urban network reliability.This paper compares the grid reliability requirements in N-1-1 outage of some developed urban areas in China and abroad,and analyzes the impact of the intra-and intersubstation contact structure on power supply capacity during N-1-1 outage.In addition,the urban network structure which can meet the N-1-1 standard of British ER P2/6 guideline is discussed,and thereupon a more stringent N-1-1 standard and corresponding network structure is proposed to accommodate the development of urban power grid.
