Distributed photovoltaic power generation refers to a distributed power generation system that uses photovoltaic modules to directly convert solar energy into electrical energy. It is a new type of comprehensive utilization method of power generation and energy with broad development prospects. It advocates the principle of nearby power generation, nearby grid connection, nearby conversion, and nearby use. It can not only effectively improve the power generation of photovoltaic power stations of the same scale, but also It effectively solves the problem of power loss in boosting and long-distance transportation.

Application scenarios of distributed photovoltaic power generation

Application range of distributed photovoltaic power generation system: It can be built in rural areas, pastoral areas, mountainous areas, developing large, medium and small cities or near commercial areas to meet the electricity demand of local users.

Solutions for Distributed Photovoltaic Power Generation

Distributed photovoltaic power generation system, also known as distributed power generation or distributed energy supply, refers to the configuration of smaller photovoltaic power supply systems at the user site or close to the power site to meet the needs of specific users and support the economy of the existing distribution network. operation, or both.

The basic equipment of the distributed photovoltaic power generation system includes photovoltaic cell components, photovoltaic square array supports, DC combiner boxes, DC power distribution cabinets, grid-connected inverters, AC power distribution cabinets and other equipment, as well as power supply system monitoring devices and environmental monitoring devices device. Its operation mode is that under the condition of solar radiation, the solar cell module array of the photovoltaic power generation system converts the output electric energy from solar energy, and sends it to the DC power distribution cabinet through the DC combiner box, and the grid-connected inverter converts it into AC power supply. The building itself is loaded, and excess or insufficient electricity is regulated by connecting to the grid.

Distributed photovoltaic power generation scheme features

1. The systems are independent of each other and can be controlled by themselves to avoid large-scale power outages, with high safety;

2. Make up for the lack of stability of the large power grid, continue to supply power in the event of an accident, and become an indispensable and important supplement to centralized power supply;

3. It can monitor the quality and performance of regional power in real time, which is very suitable for supplying power to residents in rural, pastoral, mountainous, developing large, medium and small cities or commercial areas, greatly reducing environmental protection pressure;

4. Low power transmission and distribution losses, or even none, no need to build and distribute power stations, reduce or avoid additional power transmission and distribution costs, and low civil construction and installation costs;

5. Good peak shaving performance and simple operation;

6. Since there are few systems involved in the operation, the start and stop are fast, which is easy to realize fully automatic.

Distributed photovoltaic power generation is the most widely used distributed photovoltaic power generation system, which is a photovoltaic power generation project built on the roof of urban buildings. This type of project must be connected to the public grid, and together with the public grid, provide electricity to nearby users.
