Transmission section limit power calculation based on improved-inspired bat algorithm

Abstract

The transmission section in the interconnected power grid may expand the blackout accident. It is helpful for the dispatching department to adjust operational mode in time to avoid large area blackout incidents by quickly searching the key transmission section and calculating the limit transmission power of the section. A power flow transfer ratio C is proposed in the paper, which can effectively improve the selection accuracy and speed of the K value. A correction mechanism is proposed to select the K value, which can improve the search efficiency of power transmission section based on the K shortest path algorithm. A calculation model of the ultimate transmission power of transmission sections is constructed. The improved bat-inspired algorithm is proposed to solve the model. The calculation results based on IEEE39 bus test system verify the effectiveness of this method.
