Problems solved by technology

At present, the high-voltage transmission network mainly relies on offline manual adjustment for optimization, which is not only very inefficient, but also difficult to consider various boundary constraints (for example, the power change of the 220kV substation in the high-voltage transmission system before and after network topology optimization should not exceed the given fixed range, etc.), so it cannot be applied to real-time optimization and calculation of complex transmission network topology

Abstract

The invention discloses a power transmission network topology optimization method, which comprises the following steps of constructing a power transmission network topology optimization model by taking minimum load balance and switching action times before and after power transmission network topology optimization as optimization targets and comprehensively considering eight boundary constraint conditions of topology optimization, acquiring operation data of the power transmission network in real time, and inputting the acquired operation data of the power transmission network into the power transmission network topology optimization model, and calculating and outputting the optimized network topology and switch state by the model. According to the power transmission network topology optimization model constructed by the invention, the network topology structure output according to the power transmission network operation data obtained in real time is more reasonable, and the power transmission network fault range and power failure time are reduced, and the network loss of the power transmission network in a normal state is reduced; and therefore, the reasonability of power flow distribution of the power transmission network is improved, and the operation safety of the power transmission system has high application value.

Description

technical field [0001] The invention relates to the technical field of transmission network topology optimization, in particular to a transmission network topology optimization method. Background technique [0002] The high-voltage transmission network is an important part of the energy transmission of the power system. Whether its topology structure and power flow distribution are reasonable is directly related to the power supply security of the entire region. At present, the high-voltage transmission network mainly relies on offline manual adjustment for optimization, which is not only very inefficient, but also difficult to consider various boundary constraints (for example, the power change of the 220kV substation in the high-voltage transmission system before and after network topology optimization should not exceed the given fixed range, etc.), so it cannot be applied to real-time optimization and calculation of complex transmission network topology.
