Embodiment Construction

[0020] Such as figure 1 As shown, a substation dynamic reactive power optimization method based on the improved bat algorithm, including steps:

[0021] S100: Construct a dynamic reactive power optimization mathematical model of the substation.

[0022] Reactive power optimization mainly includes two aspects, one is the optimal planning of reactive power compensation devices, and the other is optimal control of voltage and reactive power. A mathematical model is an abstract, simplified structure about part of the real world and made for a special purpose. Specifically, a mathematical model is an equation or inequality established with letters, numbers, and other mathematical symbols for a certain purpose, as well as a mathematical structural expression that describes the characteristics of objective things and their internal connections such as diagrams, images, and block diagrams.

Abstract

The invention provides a substation dynamic reactive power optimization method and a system based on an improved bat algorithm. A substation dynamic reactive power optimization mathematical model is built, the substation dynamic reactive power optimization mathematical model is solved by employing the improved bat algorithm, and the optical action strategy of a substation tap and a capacitor set is obtained. In the whole process, the bat algorithm is applied to the field of dynamic reactive power optimization, the bat algorithm is improved by employing a heuristic strategy aiming to security constraint and control equipment action constraint, the condition of local optimum of the algorithm is effectively avoided, optimal control of reactive power of the substation voltage can be realized, and normal and high-efficiency operation of the substation is guaranteed.

Description

technical field [0001] The invention relates to the technical field of substations, in particular to a dynamic reactive power optimization method and system for substations based on an improved bat algorithm. Background technique [0002] The substation in the power system is an intermediate link between the power plant and the power user. It is a power device in the power system that transforms voltage, receives and distributes power, controls the flow of power, and adjusts voltage. The power network of different levels is connected to each other through the substation. The main task of the substation is to economically provide power to users while ensuring power quality and safety. [0003] Through the effective control of the voltage and reactive power of the substation, not only can the voltage quality of the power user and the power grid be guaranteed, but also the transmission of reactive power on the transmission line can be reduced, and the active power loss of the t...
