The invention relates to a flexible load coordinated dispatching method of a distribution network based on a particle swarm algorithm, and belongs to the technical field of power grid operation and control. Including the following steps: Step 1, comprehensively considering the smoothing of new energy access, peak shaving and valley filling, and safe and economic operation of the distribution network, and establishing the optimization objective of the distribution network flexible load collaborative dispatching model; Step 2, comprehensively considering the system balance constraints, network Constraints and constraints of each distribution power supply and adjustable load, each constraint condition can be flexibly configured and effective, and establish the constraint of the optimization goal in step 1; step 3, finally use the particle swarm optimization algorithm to coordinate the load that meets the constraint condition The optimization objective of the scheduling model is solved. The collaborative control method it adopts provides space for alleviating the peak load regulation of the power grid and realizing the large-scale consumption of new energy, and its economic benefits are huge.
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...
