The First Tidal-Light Complementary Photovoltaic Power Plant Put Into Operation

On May 30, the first tidal-light complementary intelligent photovoltaic power plant in China, the National Energy Group Longyuan Zhejiang Wenling Tidal-light Complementary Intelligent Photovoltaic Power Plant, achieved full-capacity grid-connected power generation, creating a new mode of new energy comprehensive utilization of photovoltaic and tidal power generation in perfect coordination, marking China's new energy comprehensive utilization of marine energy, new energy development and construction of new energy in three dimensions, achieving new results. The power plant is the first of its kind in China and the first of its kind in the world.

The power station is the first and only tidal light complementary intelligent PV power station in China, located in Wuling Town, Wenling City, Zhejiang Province, with a total installed capacity of 100 megawatts, 24 power generation units, and more than 185,000 high-efficiency monocrystalline silicon bifacial PV modules installed in total. The power station and China's first large tidal power station complement each other, forming a "sun and moon together with the power, water and underwater power generation" scene.

It is understood that the power station intelligence, automation degree reaches the domestic first-class level, realize less people, unmanned. Power station using drone inspection technology and AI intelligent diagnostic system, relying on digital platform big data analysis, to carry out PV power generation equipment health monitoring remote diagnosis, early detection of potential equipment problems, early warning accuracy of more than 85%, reaching the industry leading, to realize the transformation from "people looking for information" to "information looking for people". The transformation from "people looking for information" to "information looking for people" is realized, which strongly guarantees the economic benefits of the power station.

In accordance with the construction idea of actively creating intelligent power generation projects, the power station is synchronized with the construction and installation of 5 MWh of energy storage equipment, is the first new energy power station in Zhejiang Province to realize the "photovoltaic + energy storage" joint primary frequency control technology. The power station makes full use of the charge/discharge replacement of the energy storage system, as well as the millisecond-level power fast response characteristics, so that it effectively changes from "adapting to grid operation" to "supporting grid operation", with an average frequency regulation effect of more than 95%, and an average response time of 200 milliseconds or less, significantly exceeding the average frequency regulation effect of 95%. The average frequency regulation effect can be more than 95%, and the average response lag time can be less than 200 milliseconds, which greatly exceeds the national standard and is at the industry leading level.
