Embodiment

[0049] In this embodiment, an IPFC planning and configuration method considering the adjustment capability of multi-flexible devices is aimed at the fact that the existing interline power flow controller (IPFC) configuration method does not fully support the mutual support of the existing flexible power electronic devices in the system. Taking the minimum IPFC investment and the maximum available transfer capability (ATC) of the power system as the optimization objectives, a multi-objective optimization model for IPFC planning and configuration is constructed. The objective function looks like this:

[0050] When the load P in the receiving area in the power system Li , Q Liand generator output P in the power generation area Gi , Q Gi Synchronous growth, the system available transmission capacity F ATC Can be described as:

[0051]

[0052] In the formula, N PQ is the number of PQ nodes in the system, λ Li is the growth ratio of the i-th load, P 0 is the total activ...

Abstract

The invention discloses an IPFC planning configuration method considering multi-flexible equipment adjustment capability, and the method fully considers the multi-flexible equipment adjustment capability, and builds a multi-target optimization model of IPFC planning configuration with the minimum IPFC investment and the maximum available power transmission capability of a system as optimization targets; and solving the provided multi-target optimization model based on a multi-target algorithm nested by a multi-target particle swarm algorithm and an interior point method, solving the available power transmission capacity of an IPFC-containing system by adopting the interior point method in an inner layer of the algorithm, and calculating a Pareto solution set of IPFC planning configuration by adopting the multi-target particle swarm algorithm in an outer layer. The model can fully consider the mutual supporting effect of the existing flexible equipment of the system, the corresponding solving algorithm can accurately and efficiently complete optimization calculation, the practical value is large, and theoretical and technical support can be provided for planning configuration and demonstration application of the IPFC.

Description

technical field [0001] The invention relates to an IPFC planning and configuration method considering the adjustment capability of multi-flexible equipment, and belongs to the technical field of power system planning. Background technique [0002] However, with the continuous increase of load, the increasingly complex grid structure, and the large-scale access of new energy sources, the uneven distribution of power flow has become an important factor restricting the transmission capacity of the power grid. [0003] IPFC is a large-scale FACTS device with more powerful functions for multi-line power flow control. It has a very broad application prospect for solving the transmission bottleneck problem of load-intensive power grids. [0004] Existing IPFC planning methods easily lead to excessive IPFC planning capacity, resulting in waste of resources, poor practicability and many other problems. Contents of the invention [0005] In order to solve the problems existing in t...
