分布式光伏发电是指将太阳能光伏发电设备分布在用户用电的地方，通过本地用电和余电回供的方式，理论上可以在一定程度上实现用户的自给自足，或为电网提供电源。以下是分布式光伏发电的工作原理：

Distributed photovoltaic power generation refers to the distribution of solar photovoltaic power generation equipment in the areas where users use electricity. Through local electricity consumption and residual electricity supply, it can theoretically achieve user self-sufficiency to a certain extent or provide power to the grid. The following is the working principle of distributed photovoltaic power generation:

光伏组件吸收日光。光伏组件吸收来自太阳的能量，将太阳光转化为电能。

Photovoltaic modules absorb sunlight. Photovoltaic modules absorb energy from the sun and convert sunlight into electrical energy.

直流电输送。电能经过逆变器的变换作用转化为直流电，然后经过电线输送到矩阵电池中寄存。

Direct current transmission. The electrical energy is converted into direct current through the conversion effect of the inverter, and then transmitted through wires to the matrix battery for storage.

负荷就地供电。直流电再经过逆变器的处理，转化为交流电，供应用户使用，称作就地供电。

Load local power supply. Direct current is then processed by an inverter and converted into alternating current, which is supplied to users for use, known as on-site power supply.

余电回馈。当直流电产生的能量大于用户所消耗的能量时，多余的电能可以回馈到电网中，成为余电供电，即余电输出。

Residual electricity feedback. When the energy generated by direct current is greater than the energy consumed by the user, the excess electrical energy can be fed back to the grid and become surplus power supply, that is, surplus power output.

综合用电与余电回馈供电。用户用电的产生往往呈不稳定的特点，因此分布式光伏发电系统还可以通过综合用电与余电回馈供电的方式，以满足各种用电需求。

Comprehensive electricity consumption and surplus electricity feedback power supply. The generation of electricity consumption by users is often characterized by instability, so distributed photovoltaic power generation systems can also meet various electricity needs through comprehensive electricity consumption and residual electricity feedback power supply.

总之，分布式光伏发电是通过将太阳能光伏发电设备分布在用户用电地方，实现就地供电和余电回馈供电的方式，可以在一定程度上实现用户的自给自足，或为电网提供电源，实现节能减排的效果。

In short, distributed photovoltaic power generation is a method of distributing solar photovoltaic power generation equipment in the user's electricity consumption area, achieving on-site power supply and residual electricity feedback power supply, which can to some extent achieve user self-sufficiency or provide power to the grid, achieving energy-saving and emission reduction effects.
