Abstract

The invention discloses an industrial power load decomposition method based on matrix decomposition. The method comprises the following steps: step S1, collecting load node data through non-invasive monitoring load node, and obtaining load data matrix; step S2, carrying out non-negative matrix decomposition on that load data matrix to obtain a base matrix and a coefficient matrix, wherein the basematrix is used for characterize a load monitoring base, and the coefficient matrix is used for characterizing parameter of the load of each electric equipment in the total load; step S3, establishinga first objective equation for optimizing the base matrix and the coefficient matrix; step S4, decomposing the load according to the optimized coefficient matrix, and the contribution proportion of each electric equipment to the total load is obtained. The invention provides an effective load decomposition method for non-invasive power monitoring, and the method can provide more accurate and morescientific reference for power load decomposition compared with existing conventional experience-based judgment method.

Description

technical field [0001] The invention relates to the technical field of electric power management, in particular to an industrial electric load decomposition method based on matrix decomposition. Background technique [0002] To carry out reasonable power demand side management, the first thing to do is to clarify the actual demand of each load node, and dynamically adjust the power supply strategy according to the actual demand of the load node and the power peak and valley status. In actual industrial applications, if each load node is monitored, it will undoubtedly bring a huge workload. At the same time, when there are too many load nodes, the complexity of implementing the dynamic scheduling algorithm will increase exponentially. Therefore, in actual industrial applications, it is usually a unit or a plant area to perform unified load management, and the monitoring of the load adopts a non-invasive method. In this way, the monitor only knows the total number of electric...
