Abstract

The invention discloses an optical storage flexible system operation control method and device. The method comprises the following steps: calculating the generation power of a distributed photovoltaic system on a prediction day and the power utilization power of a non-flexible load on the prediction day; according to the energy consumption attribute information of each type of flexible load, constructing a response model of each type of flexible load, and constructing a storage battery model; and according to the power generation power, the power utilization power, the response model of the various flexible loads and the storage battery model of the prediction day, an optimization model is constructed by taking the minimum user operation and maintenance cost, the minimum carbon dioxide emission and the maximum power self-satisfaction rate as targets, the optimization model is solved, and the operation plan of the various flexible loads and the storage battery in the prediction day is obtained. And correspondingly controlling the operation of the various flexible loads and the storage battery on the prediction day. According to the technical scheme, the power utilization load curve of the building is adjusted by changing the power utilization mode of the flexible load, distributed photovoltaic power generation is consumed as much as possible, and therefore the installation capacity of the storage battery is reduced, and the consumption cost is reduced.

Description

technical field [0001] The present application relates to the field of new energy technology, and more specifically, to a method and device for controlling the operation of an optical-storage-flexible system. Background technique [0002] Driven by the "double carbon" goal, renewable energy power generation technologies will be widely used in the future, among which distributed photovoltaic power generation technology has broad development prospects. However, distributed photovoltaic power generation is affected by solar radiation, which is intermittent, volatile, and uncontrollable. Frequent power acquisition or transmission from the grid has a large impact on the grid, which poses a huge challenge to the stable operation of the grid. [0003] At present, distributed photovoltaic power generation is usually accommodated in the form of supporting batteries. However, to realize the complete consumption of distributed photovoltaic power generation, a large-capacity battery is ...
