Smart energy integrated management and control platform

foreword

The 14th Five-Year Plan proposes: "Accelerate the promotion of digital industrialization, and cultivate and expand emerging digital industries such as artificial intelligence, big data, blockchain, cloud computing, and network security." In the first quarter of 2022, the National Energy Administration will conscientiously implement the new energy security strategy of "four revolutions and one cooperation", anchor the goal of carbon peaking and carbon neutrality, actively implement the "14th Five-Year" renewable energy development plan, and promote large-scale renewable energy development. The construction of major projects such as wind power photovoltaic bases has boosted the national renewable energy power generation to reach 533.6 billion kWh.

The rapid increase in the installed capacity of renewable energy has also brought enormous pressure to the stable operation of the power system. Since the output power of wind power and photovoltaics is greatly affected by the meteorological conditions and operating environment, it is difficult to predict the output power of the power station. It is urgent to supervise the intelligent power integrated management and control platform to ensure the smooth operation of the power grid. Using the independent research and development engine HT for Web of Tupu software, an interactive Web three-dimensional power scene is constructed, which realizes the effective management and control of new energy facilities across the country and ensures the smooth operation of the power system.

System analysis

Green smart grid system

In order to promote the construction and consumption of new energy, the "Measures for the Administration of Power Reliability (Interim)" proposes that new energy power generation enterprises should strengthen the forecast management of power generation, establish a new energy storage construction demand release mechanism, actively and steadily promote the power generation side energy storage construction, promote Source-grid-load-storage integration and multi-energy complementarity. During the "Thirteenth Five-Year Plan" period, the equivalent availability factor of my country's conventional generator sets will remain above 91%, and the equivalent availability factor of power transmission and transformation equipment such as transformers, circuit breakers, and overhead transmission lines will remain above 99% for a long time. Overall stable.

Tupu Software's double-high green smart grid system is based on the first domestic UHV AC demonstration project with the highest voltage level as the basis, and shows the transmission of current with dynamic streamer lines. It is a 1000 kV AC power transmission and transformation project with independent intellectual property rights independently developed, designed and constructed in my country - Jindongnan-Nanyang-Jingmen UHV AC Test Demonstration Project, with a total length of 640 kilometers.

By combining with HT for Web GIS products, the refined management of smart grid is realized. It supports the loading of different map tile services or data, 3DTiles format data of aerial oblique photography real scenes, and different GIS data such as urban building groups. With the technical advantages, the massive POI data, traffic flow data, planning data, status data, etc. can be displayed in a variety of visualizations in the GIS system.

UHV can effectively improve the transmission capacity of my country's power grid. The primary circuit UHV DC grid can send 6 million kilowatts of electricity, which is equivalent to 5 to 6 times that of the 500 kV DC grid, and the transmission distance is also 2 to 3 times that of the latter. To transmit electricity of the same power, if using UHV lines to transmit electricity, it can save 60% of land resources than using 500kV high-voltage lines.

The construction status of the transmission channel, Zhangxiong UHV, and Zhangbeirouzhi are updated in time on the 2D panel of the power grid system. In the smart grid system of Tupu software, the power generation and installed capacity of wind turbines, photovoltaic power generation and installed capacity are counted according to the year with a dynamic area chart that changes gradually.

The central control platform of power grid data is connected to the visualization system to realize real-time driving of new energy development, transportation, and consumption data, which is convenient for operation and maintenance to grasp first-hand information. The analysis and interpretation of energy policy, the comprehensive analysis and evaluation of regional energy resources, the preparation of development plans, and the preparation of annual plans are displayed in the Hightopo visualization system to plan the construction of subsequent new energy power facilities.

With the continuous improvement of the power grid auxiliary monitoring system, combined with the relevant characteristics and functions of the virtual-real interaction of the digital twin, users can remotely use the computer, VR and other equipment to realize the operation of auxiliary monitoring equipment through the reverse control of the platform system, and use the on-site high-definition, infrared cameras and Monitoring equipment such as intelligent robots conduct intelligent inspections of power grid equipment.

New Energy Production Supervision Center

With the goal of peaking carbon and carbon neutrality, the development and utilization of new energy in various countries has reached an unprecedented height. The United Nations' 2025 Energy Commitment Promotion Action Plan proposes that by 2025, another 500 million people will have access to electricity supply, and the global renewable energy generation capacity will increase by 100%. In China, in the first quarter of 2022, the country added 7.9 million kilowatts of grid-connected wind power. In terms of the distribution of newly installed capacity, the "Three North" regions account for about 70%, and the central, eastern and southern regions account for about 30%.

Through the visualization of Tupu software, the digital twin of the national power situation is realized, and the active power and total daily power generation of offshore wind farms and mountain wind farms across the country are counted, so as to realize production supervision, decision support, and report viewing.

Use the independent research and development engine HT for Web to seamlessly integrate 2D and 3D, and view the total installed capacity of new energy on land and total installed capacity at sea on the 2D panel; the number of companies in the access area, the number of wind farms, the total number of wind turbines, the total installed The number of inverters and the number of photovoltaic power plants can be effectively controlled.

The daily, monthly, and annual power generation of wind and photovoltaic power generation is displayed in a donut chart. The 24-hour active power of wind turbines and photovoltaic units is displayed by a line graph.

The notice of the "Measures for the Monitoring and Statistical Management of Wind Farm Utilization" points out that the calculation formula for the daily limited power of wind farms is: limited power = power generation capacity of wind farms available during the limited period - actual power generation of the wind farm during the limited period. Among them, the available power generation capacity of the wind farm’s available units refers to the remaining available wind turbines in the wind farm under the natural conditions and equipment status (without considering the influence of power system operation factors), except for equipment failures, defects or maintenance and other factors that affect the wind turbines, The amount of power that can theoretically be released in the corresponding time.

Click the map of each province in the 3D scene to pop up a 2D panel to display the installed capacity data of wind turbines and photovoltaics in each province. Dalian, Chongming, Xiamen and other regions are highlighted, click the light column to view the operation of the corresponding onshore or offshore wind farms, and the Internet of Things technology can be used to mark the faulty wind turbine in red, which is convenient for operation and maintenance to view on the large visual screen and arrange maintenance personnel to deal with it. .

With the large-scale development of offshore resources, in order to obtain more wind energy resources, offshore wind power has the characteristics of large-scale, clustered, and deep sea. Based on Web3.0, a point-to-point decentralized intelligent Internet can be established, while protecting data privacy, breaking information islands and allowing information exchange among various departments of the power system. Strengthen the unified dispatching of the whole network, and study the establishment of a power operation and market system with flexible and efficient interaction of source, network, load, and storage.

particle case

For the fluid field that needs to be displayed on one surface, such as wind field, water flow field, pressure field, etc., it needs to be presented in a dynamic way, which can be realized by using the Tupu particle plugin. In the main scene of the Tupu software visualization system, you can view the particle flow of wind power flow, global wind field, and the Yangtze River water field. The buttons on the right can freely adjust the number of particles, particle speed, particle traces, and customize particle behavior.

The global wind field simulated by HT for Web reveals the laws and trends of the complete dynamics and thermodynamic dynamic evolution of the global atmosphere, and provides the most direct and accurate initial measurement for analyzing and forecasting various extreme disastrous weather phenomena such as typhoons and rainstorms. material.

The operation of wind turbines is greatly affected by environmental factors. The airflow under specific terrain conditions is directly related to the power generation effect of wind farms. Knowing the distribution of wind energy in complex terrain environment can avoid unfavorable terrain conditions. For example, undulating terrain with a large number of steep slopes is not conducive to the development of wind farms.

Pass the 2D fluid field information to the Tupu SDK as a texture resource. The SDK uses textures to save the position information of particles, and uses the fluid field and particle position to calculate the particle position in the next frame. Then fuse the output of the previous frame and the current output to achieve the effect of the particle's moving trail.

The Tupu particle plug-in can adjust parameters such as particle size, particle shape, particle flow rate, particle number, display threshold, and simulation accuracy.
