Abstract

The invention relates to an interaction simulation and optimization method for power distribution and utilization in an industrial park comprising multiple participants. Each participant takes the minimum operating cost as an objective, and an expected exchange power is obtained through decision making; an operational platform collects the expected exchange power of each participant; by taking minimum system power loss as an objective, adjusted expected exchange power is obtained through decision making and broadcasted to each participant; interaction and optimization of the expected exchange power is carried out circularly in sequence until stopping criterion is satisfied; namely, in the interaction and optimization process, only the expected exchange power of each participant needs to be interacted; when the stopping criterion is satisfied, whether the power loss is converged to an optimal value or not is detected; and when the power loss is converged to the optimal value, the operating cost of each participant and the total system power loss achieve the optimized state, so that the minimum total operating cost is realized.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to an interactive simulation optimization method for power distribution and consumption in an industrial park with multiple participants. Background technique [0002] An industrial park is a country or region's government, according to the internal requirements of its own economic development, demarcates an area through administrative means, gathers various production factors, conducts scientific integration within a certain space, improves the intensive intensity of industrialization, and highlights industrial characteristics. Optimize the functional layout to make it a modern industrial division of labor and collaborative production area that adapts to market competition and industrial upgrading. [0003] In order to improve the economy of end-use energy, the comprehensive energy distribution and utilization system in industrial parks has received extensive attention. Carr...
