Distributed power flow controller configuration optimization method

Abstract

The invention discloses a distributed power flow controller configuration optimization method comprising the following steps: collecting the information of a power system; building a first-layer optimization function according to the constraint of the total number of relax distributed power flow controllers installed, and calculating the maximum amount of new energy consumed; and building a second-layer optimization function with the maximum amount of new energy consumed as an additional constraint, and calculating the maximum number of distributed power flow controllers installed. Based on the operation characteristics of distributed power flow controllers and by considering the installation quantity constraint of distributed power flow controllers on each line, the operation parameter constraint and the traditional power system operation constraint, the maximum amount of new energy consumed and the optimal configuration scheme of distributed power flow controllers under the performance index conditions can be calculated using the idea of double-layer optimization, which can provide guidance for the installation of distributed power flow controllers.

Description

technical field [0001] The invention relates to an optimal configuration method of a distributed power flow controller, which belongs to the technical field of flexible alternating current transmission. Background technique [0002] In recent years, due to the continuous increase in the demand for electric energy and the continuous deepening of electric energy substitution policies, power generation companies have gradually built new energy power plants to meet this growing demand. However, considering the intermittence and volatility of new energy power generation, there should be sufficient available transmission capacity for new energy power transmission in the power system. At present, there are three main methods to improve the consumption of new energy: 1) building new transmission lines in areas with high power demand; 2) improving the utilization rate of existing transmission equipment, usually using flexible alternating current transmission technology (FACTS) The f...

Problems solved by technology

[0004] At present, there is no optimal configuration method for DPFC in China, and only relevant materials describe the optimal configuration problem of traditional centralized FACTS. Traditional methods usually construct an evaluation index, and use this as a standard to determine the optimal installation location of the relevant FACTS. Finally, Solve the operating parameters of FACTS. However, this method often has certain errors in determining the position of FACTS and is difficult to determine the configuration problem of a large number of small-capacity DPFCs in the system.
