Abstract

The invention discloses a wide-area reactive power control low-voltage treatment method, which comprises the steps of: constructing a wide-area reactive power control low-voltage treatment model; adding a constraint condition on a voltage amplitude safety lower limit of a voltage infeasible node into the wide-area reactive power control low-voltage treatment model; and regarding the minimum voltage lower limit crossing amount and the lowest power loss of the voltage infeasible node as a target function, and calculating the wide-area reactive power control low-voltage treatment model by utilizing a parallel co-evolutionary algorithm to obtain the optimal voltage control scheme. The wide-area reactive power control low-voltage treatment method effectively solves the problem that the wide-area reactive power control of a power distribution network fails at the voltage infeasible node, and achieves the purpose of effectively treating the low-voltage problem in the power distribution network.

Description

technical field [0001] The invention relates to the technical field of power distribution network, in particular to a low-voltage treatment method for wide-area reactive power control. Background technique [0002] There are many 10kV rural grid feeders in some urban distribution networks with large rural characteristics. The power supply radius is long, the capacity of distribution transformers is small, the number is large, and the distribution is wide. The peak-to-valley difference of distribution transformer load is large. Insufficient reactive power compensation capacity and low feeder power factor. The voltage of these long lines in rural power grids is high when they are light-loaded, and the voltage is very low when they are heavy-loaded. The low-voltage problem of these rural power grid lines is very prominent, seriously affecting the production and life of relevant users. How to deal with the long-term low-voltage problem in the distribution network has become a k...
