Description

technical field [0001] The invention belongs to the technical field of distributed power generation and power network monitoring, and in particular relates to a photovoltaic power generation micro-grid system and a maximum power tracking method. Background technique [0002] With the rapid growth of the global economy, the demand for electricity is gradually increasing, which leads to the continuous expansion of the grid scale. The drawbacks of the traditional ultra-large-scale power system are becoming more and more prominent: on the one hand, due to the large scale and complex structure, the flexibility of power grid dispatching operation is poor, and it is difficult to guarantee the increasingly high security and reliability requirements of the economic society for the power grid; The depletion of energy and the deterioration of the earth's environment have brought challenges to the development of the power system. How to ensure the sustainable development of power has be...
