Evaluation Method of Distribution Network Carrying Capacity Based on Bayesian Network

Abstract The high-permeability distributed new energy is connected to the distribution network, which aggravates fluctuation and uncertainty of network. In order gradually improve scientificity accuracy energy-carrying capacity evaluation, it has become an essential means solve problem wind light abandonment by high-voltage DC channels realize power transmission from energy-rich areas promote interconnection carrying multiple areas. This paper proposes a calculation model maximum multi-distributed sources accessing Bayesian network limits voltage offset, fluctuation, short circuit current, subsequent current related electrical protection. Based on dynamic sensitivity constraint index capacity, segment solution method proposed deal with various constraints. Through experimental analysis, proved that speed promoting in this faster. It optimization effect for more can reasonably evaluate existing energy, provide support further research improvement strategy fluctuating energy.
