Optimal operation of active distribution network is the key technology of its economic and reliable operation. The optimal economic operation model of active distribution network is established to dispatch in order to minimize overall operation cost during the schedule period. Firstly

a variety of adjustable resources in the active distribution network are generally considered in the established model

such as distributed generators

energy storage devices

voltage regulators

switchable capacitor bank and interruptible loads. Then

a hybrid solving algorithm is proposed according to the established model based on Kriging surrogate model and a modified fuzzy particle swarm optimization algorithm

which realizes the solution to the complex problems mentioned above. Finally

the simulation results demonstrate the validity of the established optimal economic operation model and solving algorithm.
