Problems solved by technology

[0003] However, the principles of IPFC to achieve these control objectives are not the same, and there are also interactive influences and contradictory relationships among the objectives. If a certain control quantity is adjusted, other controlled quantities will fluctuate.
In addition, in view of the fact that the system has various constraints and the main objectives of attention are different under different operating conditions, if the IPFC adopts a single-objective control strategy, it cannot meet various operational requirements

Abstract

The invention discloses a multi-objective coordinated control method of an inter-line power flow controller based on fuzzy logic. The control method includes: establishing an IPFC multi-objective coordinated control system based on conventional control, formulating a corresponding coordinated control strategy; Due to the poor adaptive function under working conditions, a multi-objective fuzzy logic controller and a coordination strategy based on fuzzy adaptive control were designed. Combined with the particle swarm algorithm and the optimization samples of the traditional controller built by S1, the parameter factors of the IPFC fuzzy controller were analyzed. Carry out optimization and tap the coordinated control potential of IPFC under different operating conditions of the system. The multi-objective coordinated control method of the present invention combines the particle swarm optimization algorithm and the traditional controller optimization samples to design a multi-objective fuzzy logic controller to achieve effective control of different objectives, and formulate corresponding coordinated control strategies for the interaction between the objectives. Coordinated control potential of IPFC under different operating conditions of the system.

Description

technical field [0001] The invention relates to a multi-objective coordinated control method, in particular to a multi-objective coordinated control method of 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 power transmission capacity and flexible control level of the 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 grid operation efficiency, and optimizing power system resource allocation. Compared with the 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 and flexibly control the power flow of different lines...
