The invention relates to an energy conversion system for the energy Internet and its optimization control method, which belongs to the technical field of energy optimization. It is mainly used to solve the problems of incomplete energy conversion and utilization in the existing technology. The system includes an electric energy supply unit and a thermal energy supply unit. The control method of the unit, energy conversion center and energy output unit is to calculate the minimum value of operating cost and pollution control cost under a single target, randomly set the initial position and initial speed of particles, and limit the speed of each particle. The position and velocity of the particles are updated, the maximum membership value of the intersection membership function is obtained, the group extreme value of the particles is updated, the neighborhood solution of the current solution is generated through certain criteria, and selected from the generated neighborhood solutions Several solutions are used as candidate solutions. It is judged whether the generated candidate solutions satisfy the contempt criterion, the number of iterations of the particles is updated, and whether the latest generated optimal solution and the number of iterations satisfy the iteration termination conditions are judged.
Description
technical field [0001] The invention belongs to the technical field of energy optimization, and in particular relates to an energy conversion system oriented to the energy internet and an optimization control method thereof. Background technique [0002] Energy is the basis for human survival. In recent years, due to the excessive use of resources, the storage of non-renewable energy has been extremely reduced. In order to cope with the energy crisis, experts from various countries have devoted themselves to the research of new energy technologies. Wind energy, solar energy, tidal energy and other renewable energy have the advantages of being renewable, clean and environmentally friendly, so they are the main research objects. However, the randomness and intermittent nature of renewable energy power generation are relatively large, and the decentralized access of distributed energy will cause grid failure. The power flow distribution is complex and changeable, which not only...
