Description

technical field [0001] The present invention relates to the optimal allocation technology of active distribution network resources, in particular to the optimal allocation of active distribution network resources using the beetle whisker algorithm considering the output and load timing characteristics of distributed power sources such as wind power and photovoltaics. Background technique [0002] With the access of a large number of distributed power sources, the traditional distribution network is facing new challenges. First of all, it will have a great impact on the structure and operation of the distribution network, resulting in a bidirectional power flow between the transmission and distribution network. The load and power supply will have double uncertainties, and customers will have dual identities as consumers and producers. Secondly, the traditional distribution network is dominated by unilateral power supply and radial power supply mode. The connection of high-pen...
