A method and device for comprehensive control of low voltage in rural power distribution stations

Abstract

The invention discloses a low-voltage comprehensive treatment method and apparatus for a rural power grid power distribution district. The method comprises the steps of obtaining configuration parameters and generating a corresponding initial population; performing power flow calculation on each particle in the initial population; performing evaluation on the adaptive value of each particle in theinitial population to obtain an individual extreme value and a global extreme value of the initial population; updating the speed and position of each particle in the initial population; obtaining the current solutions corresponding to the current number of iterations in a tabu list through a particle swarm-tabu search algorithm; judging whether the preset number of iterations is reached or not or whether a preset convergence condition is satisfied or not; and if so, outputting the optimal solution from all current solutions. By combination of the tabu search algorithm and the particle swarmalgorithm, the low-voltage in the rural power grid power distribution district is subjected to comprehensive control, so that the defects of not in-time compensation and incapability of realizing global regulation and control and incapability of realizing in-time and dynamic low-voltage district management caused by single control can be avoided; and the problem of low-voltage in the rural power grid power distribution district can be solved intelligently and efficiently in time.

Description

technical field [0001] The invention relates to the field of voltage monitoring and management of power grid distribution stations, in particular to a low-voltage comprehensive management method and device for rural power distribution stations. Background technique [0002] The rural power grid is the last link from the power system to the rural electricity users. It has the closest connection with users and has the most direct impact on the reliability and quality of power supply for users. The safe, reliable and economical operation of the power grid is not only related to the economic benefits of power companies, but also has great significance for improving user satisfaction and establishing a good corporate image. Therefore, how to ensure that the rural power grid has sufficient capacity to receive electricity and provide high-quality power supply for regional economic and social development and people's living standards is the main task of rural power grid planning. ...

AI Technical Summary

Problems solved by technology

[0003] In the existing technology, the low-voltage control method of the rural power distribution station area is often through a single control, so that the compensation is not timely, the overall regulation cannot be adjusted, and the low-voltage station area cannot be dynamically controlled in real time.
