Abstract

The invention relates to a distribution network flexible load cooperative dispatching method based on a particle swarm algorithm, belonging to the technical field of grid operation and control. The method comprises the following steps of: (1) considering stabilizing new energy access, peak clipping and valley filling and safe and economical operation of distribution network, establishing an optimization objective of flexible load cooperative dispatching model of distribution network; 2, synthetically considering the system balance constraint, the network constraint, the distribution power source and the adjustable load constraint, wherein each constraint condition can flexibly carry out parameter configuration and effective setting, and establishing the constraint of the optimization objective in the step 1; and 3, finally, solving the optimization objective of the load cooperative dispatch model satisfying the constraint condition by using the particle swarm optimization algorithm. This kind of cooperative control method provides space for alleviating the peak load regulation and realizing the large-scale consumption of new energy, and its economic benefits are enormous.

Description

technical field [0001] The invention relates to a method for coordinated dispatching of a distribution network, a method for coordinated dispatching of flexible loads in a distribution network based on a particle swarm algorithm, and belongs to the technical field of power grid operation and control. Background technique [0002] The power system generation plan model is the basis for power grid dispatching and generation planning. Whether the model can faithfully reflect the characteristics of the power system and the accuracy of the model will directly affect the safety, reliability and economy of the final plan. With the large-scale grid-connection of wind power, the power generation planning model should consider the impact of wind power characteristics, realize joint optimization considering large-scale wind power grid-connection, and improve the system’s ability to accommodate wind power, system operation safety, reliability, and economy. sex. For the transmission gri...
