The present invention relates to an energy conversion system facing energy Internet and an optimal control method thereof, belonging to the technical field of energy optimization. The invention aims to solve the problem of the incomprehensive utilization of energy conversion in the prior art. The system comprises an electric energy supply unit, a heat energy supply unit, an energy conversion center, and an energy output unit. The control method comprises the steps of randomly setting the initial positions and initial speeds of particles through calculating the minimum values of the operation cost in a single target and pollution treatment cost, limiting the speed of each particle, updating the positions and speeds of the particles, obtaining the maximum membership value of an intersection membership function, updating the population extreme value of the particles, generating the neighborhood solutions of a current solution through a certain criteria, selecting a plurality of solutions from the generated neighborhood solutions to be candidate solutions, judging whether the generated candidate solutions satisfy a contempt criterion, updating the number of iterations of the particles, and judging whether the latest generated optimal solutions and the number of the iterations satisfy a termination condition.
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...
