Distributed photovoltaic (PV) power generation specifically refers to distributed power generation systems that use photovoltaic modules to directly convert solar energy into electrical energy. It is a new type of power generation and comprehensive energy utilization method with broad development prospects. It advocates the principles of local power generation, local grid connection, local conversion, and local use, which not only effectively increases the power generation of PV power plants of the same scale but also effectively solves the problems of power loss during voltage boosting and long-distance transmission.
Application scenarios of distributed photovoltaic power generation
Applications of distributed photovoltaic power generation systems: They can be built in rural areas, pastoral areas, mountainous areas, and near developing large, medium and small cities or commercial areas to meet the electricity needs of local users.
Distributed photovoltaic power generation solutions
Distributed photovoltaic (PV) power generation systems, also known as decentralized power generation or distributed energy supply, refer to small-scale PV power generation systems configured at or near user sites to meet the needs of specific users, support the economic operation of existing power distribution networks, or simultaneously meet both of these requirements.
The basic equipment of a distributed photovoltaic (PV) power generation system includes PV modules, PV array supports, DC combiner boxes, DC distribution cabinets, grid-connected inverters, and AC distribution cabinets. Additionally, it includes power supply system monitoring devices and environmental monitoring devices. Its operating mode is as follows: under solar radiation conditions, the PV system's solar cell array converts solar energy into electrical energy, which is then collected by the DC combiner box and fed into the DC distribution cabinet. The grid-connected inverter then converts this electrical energy into AC power to supply the building's own load. Excess or insufficient power is regulated by connecting to the power grid.
Features of Distributed Photovoltaic Power Generation Scheme
1. The systems are independent of each other and can be controlled independently, avoiding large-scale power outages and ensuring high safety;
2. It compensates for the instability of the main power grid, continuing to supply power in the event of an accident, thus becoming an indispensable and important supplement to centralized power supply;
3. It can monitor the quality and performance of regional power in real time, making it ideal for supplying electricity to residents in rural areas, pastoral areas, mountainous areas, and developing large, medium, and small cities or commercial areas, greatly reducing environmental pressure;
4. Low or even zero transmission and distribution losses, eliminating the need for substations, reducing or avoiding additional transmission and distribution costs, and lowering civil engineering and installation costs;
5. Excellent peak-shaving performance and simple operation;
6. Due to the small number of systems involved in operation, startup and shutdown are quick, making it easy to achieve full automation.
Distributed photovoltaic (PV) power generation is the most widely used type of distributed PV power generation system. It consists of PV power generation projects built on the rooftops of urban buildings. These projects must be connected to the public power grid to supply electricity to nearby users.
