The characteristics of a distributed photovoltaic power station
A distributed photovoltaic (PV) system refers to a photovoltaic power generation facility constructed near the user’s location, primarily designed to meet the user’s own energy consumption with surplus power being fed into the grid. It is characterized by its balance regulation within the distribution system.
Distributed PV systems advocate for local generation, local grid connection, local conversion, and local use, effectively addressing the loss of electricity during the process of voltage boosting and long-distance transmission. It represents a new and promising method of power generation and integrated energy utilization.
Distributed photovoltaic systems can be divided into two modes based on consumption patterns:
"Full grid connection" where all the electricity generated by the system is fed into the grid.
"Self-consumption with surplus power fed into the grid," where the electricity generated by the system is first used by the user, and any surplus is fed into the grid.
Common types of distributed photovoltaic power stations include rooftop PV systems in commercial and industrial settings, fish-solar complementary systems, agricultural-solar complementary systems, forestry-solar complementary systems, and photovoltaic building integration (BIPV).
Characteristics of distributed photovoltaics:
Located near the user.
Connected at 10 kV or lower.
Connected to the distribution network and consumed locally.
Single-point capacity does not exceed 6 MW (with multiple connections, the maximum limit is based on the largest connection).
