Problems solved by technology

This involves the optimization of the MPPT algorithm. The traditional optimization method uses a constant voltage, but this method needs to measure the maximum output power of the solar panel in advance, and requires a specific solar panel and the corresponding system to maintain the maximum output power.
There is also a method of using disturbance observation, but the tracking speed of this method is very slow and is susceptible to external interference
There is also a method of increasing conductance, but this method is susceptible to external interference and there is a situation where the maximum output power cannot be tracked

Abstract

A power tracking method based on a PID-based MPPT controller. The input power is processed by the conductance method and then output to the power loop. At the same time, a feedback signal is added to each loop, and it is the feedback signal at the output of the MPPT controller, so that The power loop, voltage loop and current loop can all get feedback signals, and then perform PID control processing, so that the signals at the output terminals of the power loop, voltage loop and current loop can be corrected to the maximum extent. Under certain circumstances, it is not necessary to measure the target voltage point of the maximum output power of the MPPT controller in advance, and directly track the maximum output power of the MPPT controller quickly and stably. In addition, a power tracking system based on the PID MPPT controller is also provided.

Description

technical field [0001] The present application belongs to the technical field of MPPT controller power tracking, and in particular relates to a PID-based MPPT controller power tracking method and system for fast and stable tracking to maximum output power without measuring voltage points. Background technique [0002] At present, when charging with solar energy outdoors, it is necessary to charge the energy storage device quickly. Therefore, it is necessary to convert solar energy into electrical energy to the maximum extent and output it to the energy storage device. This involves the optimization of the MPPT algorithm. The traditional optimization method uses a constant voltage, but this method needs to measure the maximum output power of the solar panel in advance, and a specific solar panel and the corresponding system can maintain the maximum output power. There is also a method of using disturbance observation, but the tracking speed of this method is very slow and is ...
