A Differentiation Based Framework to Multi-Objective Transmission Expansion Planning Considering Meteorological Disaster

The frequent occurrences of meteorological disasters (MD) have revealed the deficiencies of the transmission expansion planning (TEP). The traditional TEP methods fail to establish the mathematical relationship between the MD and the transmission component outage rate (TCOR) when calculating the outage cost of customer. As a result, the optimized schemes are unable to determine the minimum backbone grid that should be guaranteed in the event of MDs, which is against the basic principles of economy and reliability. In this paper, the research status of multiobjective TEP is reviewed and the mathematical relationship between MD and TCOR is investigated preliminarily. On this basis, a differentiation based framework to multi-objective TEP is proposed and discussed, which is of significant reference value to the TEP under the meteorological disaster-prone environment.
