Research on Comprehensive Assessment Index System for Transmission Network Planning Alternatives

In view of the lack of comprehensive and quantitative evaluation means for transmission network planning currently, a comprehensive assessment index system adapted to the characteristics of the transmission network planning is proposed, including 6 strategic layer indices (safety and reliability, economic efficiency, flexibility and coordination, smart and green, controllable risk and social benefits), 16 target layer indices and 57 operating layer indices. And the assessment standard for each index is determined to provide objective, comprehensive and systematic evaluation of transmission network planning alternatives as well as prepare for realization of the comprehensive evaluation of transmission network planning.
