Active power distribution network optimization control method based on information physical fusion model

Abstract

The invention provides an active power distribution network optimization control method based on an information physical fusion model. The method comprises the following steps: S1, setting a control period T; s2, setting a control signal state vector dimension s, and establishing a control information conversion model; s3, setting a control system node connection relation incidence matrix and establishing a hierarchical distribution control system model; s4, the initialization time is the starting time Time = t, and a primary system hybrid system model is established; s5, establishing an information physical fusion model of the active power distribution network layered distribution control system; s6, constructing a control objective function min J; s7, converting the problem into a mixed integer programming problem with a quadratic term in a target function, and solving a control quantity in a control period; s8, executing s control quantities of the control period; and S9, the time recursion is that the next time Time is equal to t + delta T, if the current time Time is the deadline, the operation is stopped, otherwise, the step S5 is executed, and optimization control is performed on the next period.

Description

technical field [0001] The present invention relates to the comprehensive management and control of complex systems in the field of active distribution networks. The present invention provides an optimal control method for active distribution networks based on a cyber-physical fusion model, which provides support for the management and control of complex systems considering cyber-physical interactions. Realize optimal control under the premise of taking into account the time-consuming process and the processing capacity of the information system. Background technique [0002] As the main development direction of the modern industrial system, informatization has brought a huge impact and impact on traditional production. In the process of combining information and production, it is natural that the production system is the mainstay and the information system is the supplementary. In other words, information systems are generally designed and added to achieve specific physica...
