Problems solved by technology

The present invention provides a voltage regulation and current sharing method based on a three-layer forward neural network. On the basis of the proposed current sharing controller, a new controller is constructed using pre-compensation technology, and the system error about voltage and current is constructed by the controller to solve the problem. Environmental impact, circuit aging and other unknown factors cause voltage drop and the voltage and current cannot be adjusted or the adjustment fails.

Embodiment Construction

[0108] In order to make the objects, technical solutions, and advantages of the present invention, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are merely the embodiments of the invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative labor are in the range protected by the present invention.

[0109] In either embodiment, if figure 1 The hierarchical control model of the DC microgrid is a DC microgrid consisting of m power and N loads, each power supply node communicates with its neighbors through a wide area network, ie output voltage, current, and unit of each node. Power, the impedance of this unit line is related, and it is also determined by the output of its adjacent parallel units. Each power supply is connected to the bus by a boost DC / DC converter, and the load is connec...

Abstract

The invention discloses a neural network-based voltage regulation and current sharing method, which is characterized in that a new controller is constructed by adopting a pre-compensation technology on the basis of a model with unknown voltage drop, dynamic calculation on a system is avoided, secondary auxiliary control of a control unit and a computer network carry out information transmission to regulate voltage and current, information sensing with the outside exists, voltage regulation and current sharing can be effectively achieved, and the stability of the system is improved.

Description

Technical field [0001] The present invention relates to the field of electricity electronics engineering, and more particularly to a voltage regulation and current current flow method based on a neural network. Background technique [0002] The grid is a power generation and power distribution network system consisting of a distributed power supply, an energy conversion device, an energy storage device, and a load. The micro-grid is one of the important components of the smart grid, which is of great significance for promoting energy conservation and emission reduction and achieving energy sustainable development. At present, there are two types of microgrid: DC microgrid and AC microgrid. Compared with the AC microgrid, wind, light and other distributed renewable energy power generation systems, household appliances, energy storage equipment and other DC power loads can be efficient and reliably access DC microgrid. Therefore, the DC microgrid has been widely concerned by resear...
