Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic power generation, and in particular to a rooftop distributed integrated photovoltaic power generation system. Background Art

[0002] With the development of economy, energy shortage is a problem faced by all countries in the world. At the same time, as the most important available petrochemical energy materials such as coal, oil, natural gas, etc. are facing the danger of depletion, the problem of energy shortage is becoming more and more serious and affecting people's living standards. On the other hand, the environmental pollution and climate warming brought by petrochemical energy can no longer be ignored, affecting the development and promotion of sustainable development, energy conservation and environmental protection concepts, and are attracting more and more attention. Among many new energy sources, solar energy has the advantages of clean and pollution-free, safe and reliable, less restricted, inexhaustible and sustainable use, thus having incomparable advantages. Distributed power generation can consume electricity locally, save power transmission and transformation investment and operating costs, and reduce the line loss of centralized power transmission; and it complements the power supply of large power grids, reduces the capacity of the power grid, improves the peak and valley performance of the power grid, and improves the reliability of power supply.

[0003] However, photovoltaic power generation itself has the characteristics of randomness and intermittency that are different from conventional power sources. Its grid-connected operation poses a certain threat to the power quality and safe and stable operation of the power grid. On the one hand, the injection of photovoltaic power changes the power flow distribution of the local power grid, which has a great impact on the voltage quality and stability of the local power grid, and limits the way and scale of photovoltaic power generation access to the system. On the other hand, the original power of photovoltaic power generation is not very controllable. Whether it is in the power generation state and the amount of power output are limited by weather conditions and the performance of the photovoltaic system. From the perspective of the power grid, grid-connected photovoltaic power generation is equivalent to a random disturbance source, which may affect the reliable operation of the power grid at any time. Therefore, the grid operation and safety problems caused by the power quality, instability, island effect, etc. of the above-mentioned photovoltaic power generation system will greatly limit the large-scale promotion and application of small-scale distributed photovoltaic power generation systems in my country.
