A method for multi-objective evaluation of active distribution network power supply capability

A method for multi-objective evaluation of power supply capability of active distribution network includes the following steps: 1) establishing constraint conditions of active distribution network considering source network load control, the output of fan and photovoltaic in active distribution network is generated by Monte Carlo sampling, Distributed-Generation-Based output, Network topology, load response constraints to generate the corresponding active distribution network source network load coordination scheme, according to the fan, photovoltaic output and the corresponding load level andactive distribution network grid structure power flow calculation, power flow calculation results based on chance constraints to determine whether to meet the confidence in the probability constraintconditions; 2) if yes, calculating that power supply capacity of the active distribution network and the cost of source network load control, if not, re-assigning the two objective function values toexecute step 3); 3) utiliz
