Embodiment Construction

[0091] The present invention will be further described below with reference to the accompanying drawings.

[0092] The site selection and capacity configuration method for UPFC of the present invention establishes a transient stability constraint UPFC site selection and capacity configuration model, takes the differential evolution algorithm as the framework, optimizes the installation position and capacity of the UPFC, and adopts the center calibration method. The point method optimizes continuous variables and evaluates the fitness of each differential evolution individual. Due to the simple operation of the differential evolution algorithm, strong search ability, and few adjustment parameters, it is suitable for hybrid optimization and the interior point method has the advantages of good convergence and strong robustness. , the proposed hybrid algorithm can better solve the problem of UPFC location selection and capacity configuration, and is efficient and convenient, such a...

Abstract

The invention discloses an addressing and capacity configuration method used for a UPFC. A UPFC addressing and capacity configuration model with transient stability constraints is established, a difference evolution algorithm serves as a framework, and the installation position and the capacity of the UPFC are optimized; in addition, a centrality correction interior point method is adopted for carrying out optimization and fitness assessment on continuous variables of each difference evolution unit. The difference evolution algorithm is simple in operation, high in searching capability, fewer in adjusting parameters and suitable for mixed optimization, and the interior point method is good in convergence and strong in robustness, so that the provided mixed algorithm can well solve the problems of UPFC addressing and capacity configuration, the method is highly efficient and convenient, and the application prospect is good.

Description

technical field [0001] The present invention is in the technical field of power system operation and control, in particular to a method for site selection and capacity allocation for UPFC. Background technique [0002] With the development of power grid construction, the connection between regional power grids is getting closer and closer. Under the current power grid network structure, it is difficult to safely conduct electricity transactions between regional power grids. Flexible AC transmission systems (FACTS) is a new technology that has emerged in recent years. It applies the latest development achievements of power electronics technology and modern control technology to achieve flexible and fast control of AC transmission system parameters and network structure. Reasonable distribution, reduce power loss and power generation cost, and greatly improve system stability and reliability. [0003] The unified power flow controller (UPFC) is the most complex and attractive...
