Problems solved by technology

At present, some scholars have extended NILM technology to the decomposition of house water consumption, building cooling load, photovoltaic power generation, etc., but there are relatively few studies on non-intrusive load decomposition of integrated energy systems. Some researchers use generative confrontation network (GAN) Non-intrusive modeling of integrated energy systems, but the research object is still energy equipment

Embodiment 1

[0054] On the basis of analyzing the existing research results, the invention expands the non-intrusive load decomposition of the power system to the comprehensive energy system, and changes the research object from residential appliances to multi-energy users. Considering that most of the users in the park IES are multi-energy users, the traditional single energy load decomposition method cannot make good use of the multi-energy coupling relationship. Therefore, this embodiment proposes a non-intrusive load of the park IES based on multi-task deep learning. The decomposition method handles the multi-energy coupling relationship in the form of parameter sharing, realizes real-time and accurate acquisition of multi-energy load information within the system, and helps park operators better manage the integrated energy system.

[0055] First of all, due to the large number of users in the IES in the park, modeling one by one requires high cost. First, users are divided according t...

The method comprises the following steps: acquiring total load data of the park integrated energy system and energy consumption data of each user; dividing user clusters according to the energy consumption data to obtain user clusters of different energy consumption types; performing correlation analysis on the plurality of loads of each user cluster and the influence factors to obtain the influence factors corresponding to each user cluster, wherein the correlation of the influence factors is greater than a preset amount; for a certain user cluster, obtaining a multi-energy load decomposition result corresponding to the user cluster according to the total load data, the influence factor data and the load decomposition model corresponding to the user cluster; performing multi-energy load decomposition of each user cluster in sequence to obtain a final multi-energy load decomposition result; and the precision of non-intrusive load decomposition of the park integrated energy system is improved.

Description

technical field [0001] The invention relates to the technical field of load decomposition, in particular to a non-intrusive load decomposition method and system for a park comprehensive energy system. Background technique [0002] The statements in this section merely provide background art related to the present invention and do not necessarily constitute prior art. [0003] At present, the integrated energy system (Integrated Energy System, IES) has gradually developed into an important energy utilization method, among which the park integrated energy system is a typical form of multi-energy coupling and utilization on the user side. Different from traditional energy systems, there are multiple energy conversions and storages inside the park IES, which puts forward new requirements for the planning and operation of the system. Therefore, it is of great significance to obtain the multi-energy load information in the park in real time. [0004] Due to the information barri...
