Abstract

The invention discloses an inter-line power flow controller multi-target coordination control method based on fuzzy logic. The method comprises the steps: building an IPFC multi-target coordination control system based on conventional control, and formulating a corresponding coordination control strategy; aiming at the defect that a traditional controller is poor in adaptive function under different working conditions, designing a multi-target fuzzy logic controller and a coordination strategy based on fuzzy self-adaptive control; and optimizing the parameter factors of the IPFC fuzzy controller by combining a particle swarm algorithm and the optimization sample of the traditional controller established in the step S1 so as to mine the coordination control potential of the IPFC under different operation conditions of the system. According to the invention, a multi-objective coordination control method is combined with a particle swarm optimization algorithm and a traditional controlleroptimization sample, a multi-objective fuzzy logic controller is designed, effective control over different objectives is achieved, a corresponding coordination control strategy is formulated according to the interaction influence between the objectives, and the coordination control potential of the IPFC under different operation working conditions of the system is mined.

Description

technical field

[0001] The invention relates to a multi-objective coordinated control method, in particular to a multi-objective coordinated control method for an inter-line power flow controller based on fuzzy logic. Background technique

[0002] As a representative device of a new type of Flexible AC Transmission Systems (FACTS), the Interline Power Flow Controller (IPFC) can greatly improve the transmission capacity and flexible control level of the power grid, saving valuable corridors Resources and investment in new transmission channels provide new ideas for increasing the utilization rate of power grid transmission channels, improving the efficiency of power grid operation, and optimizing the allocation of power system resources. Compared with the unified power flow controller (Unified Power Flow Controller, UPFC), which is also the third-generation FACTS device, this new device can balance the power flow of each transmission channel, and at the same time accurately a...
