Introduction: The wind and solar energy storage integrated monitoring system independently developed by Guodian Nanrui can be called the “smart brain†of wind and solar storage power stations. The scenery, storage, and panorama monitoring system has achieved a series of innovations and breakthroughs in power generation control, voltage control, power generation forecasting, power generation planning, operation analysis, and panoramic monitoring.
The main interface of the scenery integrated storage monitoring system shows orange, blue, yellow, red, green and five curves: Orange represents the energy storage capacity, which is complementary to the blue wind power output and the yellow photovoltaic output. The green curve is the actual power generation output of the entire power plant and is fluctuating around the red power generation plan curve.
This is the control core of the entire joint power generation system in the National Wind Energy Storage and Demonstration Project, which is an integrated monitoring system for scenery, wind and storage, and independently developed by Guodian Nanrui. The system can be called the "wisdom brain" of wind and solar storage power stations. Through the coordinated and coordinated control of three types of wind power, photovoltaic, and energy storage, the volatility and intermittency of wind power and photovoltaic output are improved, making the output characteristics of wind and solar power storage stations similar to the power grid similar. As for conventional energy sources, it can be safely and stably integrated into the operation of the power grid, marking a major breakthrough in China's comprehensive utilization of new energy technologies.
The scenery, storage, and panorama monitoring system has achieved a series of innovations and breakthroughs in power generation control, voltage control, power generation forecasting, power generation planning, operation analysis, and panoramic monitoring. In terms of power generation control, the system adopts the “multiple energy complementary†technology and provides a variety of power generation control modes. It can achieve smooth control, tracking planning, tracking network adjustment instructions, and tracking given targets under different combinations of wind, light, and storage. And other controls. In terms of voltage control, the “multi-source synergy†technology is adopted to comprehensively utilize various reactive power sources within the wind-storage-storage power generation system throughout the day.
The application of visualization technology makes the operation of the system more convenient. Before a clear system interface, staff can intuitively monitor the power generation of wind power, photovoltaic power generation and energy storage systems throughout the plant. Taking a wind farm as an example, the operation status of each wind turbine in Xiaodongliang and Meng Jialiang's two wind farms is under the effective monitoring of the “smart brainâ€. Once a fan fails, the system interface will warn, after clicking the fan icon can also analyze the operating data of the key components inside the fan, such as the generator, wind wheel, gear box and other components running status, the staff can thus make Corresponding maintenance decision.
In terms of power generation plan, the system has applied the optimal scheduling technology of wind and solar storage, according to a certain period in the future, such as short-term (24 hours) or even ultra-short-term (2 to 4 hours in the future) wind power capacity forecast, photovoltaic power generation capacity forecast and energy storage capacity According to the objective of minimizing wind power fluctuation, and peaking capacity, we will formulate an optimal short-term wind-storage combined power generation plan. Previously, the application of this technology was still a blank at home and abroad.
"Because the panoramic integrated monitoring system can realize the active and reactive control under the complex mode of combination of scenery and storage 'adding', in other combinations, this monitoring system only needs to do 'subtraction' properly to apply to the wind. Individual, light alone, scenery combination, wind storage combination, optical storage combination, etc. Therefore, the application of panoramic integrated monitoring system is very broad.†Gaozong, a power grid technology expert of the State Grid Power Institute of Science and Technology said proudly.
The National Wind Energy Storage and Demonstration Project was completed and put into operation on December 25, 2011. It is located in Zhangbei County, Hebei Province. This project is the largest in the world and integrates new energy sources including wind power, photovoltaic power generation, energy storage, and intelligent power transmission. The use of the platform is also a key project of the National Golden Sun Project, a major project of the National Science and Technology Support Plan, and the first batch of pilot projects of the State Grid Corporation of China's strong smart grid. In the first phase of the project, 100,000 kilowatts of wind power, 40,000 kilowatts of photovoltaic power generation, and 20,000 kilowatts of stored energy have been built, supporting the construction of a joint storage and transportation control center for wind and solar energy and a 220 kilovolt smart substation. At present, the scenery, storage, and panoramic monitoring system works well.
