Maximum Power Point Tracking Method for Photovoltaic Power Generation System Based on Improved Wolf Pack Algorithm

Abstract

The invention provides a photovoltaic power generation system maximum power point tracking method based on an improved wolves algorithm, and relates to the technical field of photovoltaic power generation. According to the method, the initialization of the wolves is firstly carried out, then the detection wolf wandering with variable step sizes and variable directions, the fierce wolf moves to thehead wolf position according to the bad running principle, executes the siege attack action, finally, the head wolf carries out hunting behavior, and the wolf group is undated according to the updating mechanism of 'only the strong survive', weather iterative computation is determined according to the termination condition, thereby obtaining the maximum power point of the photovoltaic power generation system. According to the present invention, the photovoltaic power generation system maximum power point tracking method based on an improved wolves algorithm is provided, the improved wolves algorithm is used to solve the problem of unstable power output of a photovoltaic cell, so that the output power of the photovoltaic cell is maximized, the tracking speed and the tracking precision of the maximum power point are improved, and the photoelectric conversion rate is improved.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a method for tracking the maximum power point of a photovoltaic power generation system based on an improved wolf pack algorithm. Background technique [0002] Energy is not only a support for social and economic progress, but also a necessary material for human survival. At present, the storage capacity of traditional fuel energy such as oil and coal has been gradually reduced with the development of society, and the release of harmful substances has caused great damage to the environment. harm. In order to solve this situation, human beings have turned their attention to renewable energy, through the research and use of renewable energy to change the existing energy structure and maintain the sustainable development of energy. [0003] The energy generated by the sun every second is equivalent to the energy of 500 million barrels of oil. If 0.1% of the so...

Problems solved by technology

However, there are still some shortcomings in the traditional wolf pack algorithm, such as the fixed walking direction of the wolves, the inability to dynamically adjust the walking step length, the lack of information exchange between artificial wolves, and the head wolf not participating in intelligent behavior.
