Intelligent building power utilization strategy acquiring method based on self-adaptive particle swarm algorithm

The invention relates to an intelligent building power utilization strategy acquiring method based on a self-adaptive particle swarm algorithm. As for a building provided with at least two power supplies, firstly, a preset number of power utilization schemes of the building at each time period of preset future application and implementation time are acquired on the premise that characteristic requirements of each power supply are met, then, iteration is performed according to each power utilization scheme, the lowest power utilization cost in each iteration process is acquired, and finally, the lowest power utilization cost is acquired from the corresponding lowest power utilization costs in all the iteration processes. The power utilization scheme corresponding to the power utilization cost is the optimal power utilization strategy at each time period of preset future application and implementation time, so that the best power utilization strategy capable of realizing the target of the minimum electric cost expenditure is provided.
