The 2 million kilowatt composite photovoltaic base project in Ningdong Town, Lingwu City, Yinchuan City, Ningxia is one of the first batch of "Sha Ge Huang" large-scale wind power photovoltaic base projects in China. It is also the largest new energy project with the largest single scale and largest investment scale in Ningxia. As an important green energy base for Ningxia's Lingshao DC "West-to-East Power Transmission" project, after achieving full capacity grid-connected power generation on June 30, it will be transmitted to Zhejiang through the Lingshao ±800 kV UHV DC transmission project. It is expected to generate electricity every year. Zhejiang transported 3.15 billion kilowatt-hours of green electricity, saved approximately 1.15 million tons of standard coal, and reduced carbon emissions by approximately 3.15 million tons.
The project is divided into three photovoltaic power stations, namely Ningdong 32nd to 34th photovoltaic power stations, with installed capacities of 1GW, 500MW, and 500MW respectively. SPRIXIN provides the 33rd PV power plant with power forecast and the 34th with both power forecast and AGC/AVC products and services.
The total installed capacity of 1GW makes it more difficult to ensure the accuracy of power forecasting. In particular, the photovoltaic area covers an area of nearly 30,000 acres, making photovoltaic power generation efficiency more susceptible to the influence of clouds. SPRIXIN has rich experience in new energy power forecasting at home and abroad. It has in-depth data accumulation and research on cloud images, cloud cover, and other data. It combines authoritative data sources and multi-dimensional algorithm models based on micro-terrain, micro-meteorology, extreme weather, etc. to professionally The superb forecasting technology overcomes many difficulties and provides reliable technical guarantee and service support.
In addition, the 500MW installed capacity of Ningdong No. 34 Photovoltaic Power Station also places high requirements on the performance of AGC/AVC. After calculation, to meet the Ningxia power grid dispatching requirements, the power station's AGC/AVC requires a total of more than 190 communication channels to achieve timely and stable responses. For this purpose, SPRIXIN has developed a customized intelligent grid-connected control scheme. On the basis of adding supporting hardware, it has specially developed a multi-node acquisition system for Ningdong No. 34 Photovoltaic Power Station, which provides precise control and rapid response to protect the safety and efficiency of the power station. run.
With the official commissioning of the Ningdong 2 million kilowatt composite photovoltaic base project, Ningxia's new energy installed capacity has reached 30.4 million kilowatts, accounting for more than 50% of the installed capacity. New energy has surpassed coal power and become the largest power source in Ningxia's power grid. SPRIXIN will continue to leverage its technological advantages to add new momentum to the construction of a clean, low-carbon, safe, stable, flexible, and intelligent new power system.
