Shandong Electric Power Institute's electric vehicle technology achievements reach international advanced level

Recently, the State Grid Shandong Electric Power Company hosted the “Study and Application of Simulation and Coordinated Control Technology for Electric Vehicle Charge and Replacement Services” completed by the State Grid Shandong Academy of Electric Power and Shandong Luneng Intelligent Technology Co., Ltd. in Jinan. meeting. An appraisal committee composed of 10 experts inside and outside the industry, including the China Electric Power Enterprise Association, the China Electrical Engineering Society, and Shandong University of Technology, after listening to the project technical report and viewing related materials, after discussions and inquiries, agreed that the project has With a broad application prospect, the research results have reached an internationally advanced level overall.

The project adopts Erlang language for concurrent, distributed, and fault-tolerant, developed a distributed data acquisition and storage system for an electric vehicle charging and swapping service network, and realized the collection of over 100,000 data acquisition channels and millions of real-time measurement data. storage. Based on the study of the operating characteristics of electric vehicles and charge and charge facilities, a layout planning and operation simulation evaluation system for electric vehicle charging stations was developed, and an ecological simulation model for charging and replacement networks including charging facilities, electric vehicles and road networks was established, according to the location of charging stations. The process of planning, running simulation and evaluation of indicators, and recharging and recharging of the charging stations provide indicators for evaluating and optimizing solutions for the configuration, distribution and service capabilities of the charging and changing service network. Carried out research on the control strategy of dynamic car exchange and charging service network, established a load control model for electric vehicle charging and switching stations, developed a coordinated control system for electric car charging and swapping service network, and cut peaks and fill valleys, economic operation, etc. The strategy dispatches charging and swapping facilities to achieve coordinated control of the grid load and the charging requirements of electric vehicles. Carry out research on cooperative scheduling of renewable energy such as photovoltaics and charging/discharging of electric vehicles. Developed an electric vehicle charging/discharging service network to optimize the dispatching of charging loads and load forecasting software. The charging and discharging scheduling algorithm for electric vehicles and the charging and discharging of electric vehicles can be developed. The exploration of the coordination and optimization of renewable energy generation.

The results of this project have been successfully applied to the Jinan Power Supply Company of the State Grid and the Qingdao Power Supply Company of the State Grid, gaining praise from users. The electric vehicle charging and swapping service network planning simulation and coordination control system developed by this project has been successfully connected to the power station data in Jinan, Linyi, and Qingdao, providing basic research data for planning simulation and coordination control. In Beizhuang, the application of coordinated dispatching and optimal control of charging and exchanging electric vehicles and photovoltaic energy storage is achieved in Beizhuang, and good results are achieved. The automation and information level of electric vehicle charging and replacement service network operation and management is improved, and the requirements for safe and stable operation of power grid are met. .

The application of the project is of great significance in guiding the planning and operation of electric vehicle charging stations, the coordinated control of charging stations and power grids, and the integration of renewable energy and charging and changing service networks. This project is aimed at the particularity of the charging load of electric vehicles connected to the power grid and can effectively improve the efficiency of power grid operation management decisions. Its research results can provide theoretical and technical support for the construction of electric vehicle charging stations, and it is studying the charging model of electric vehicles and its Based on the synergy of renewable energy, the impact of electric vehicle charging stations on the regional power grid is analyzed. Based on this, the electric vehicle charging stations are rationally planned and designed to achieve the coordinated use of smart grid platform resources, and promote the development of renewable energy and energy conservation and emission reduction. .

The construction of electric vehicle charging and changing network is the support for the rapid development of electric vehicles. The planning and construction of reasonable charging and replacing facilities is an important research content. At the same time, the charging of a large number of electric vehicles is bound to have an impact on the safe operation of the power grid and it is reasonable to proceed. Charging and replacing power coordination control is a necessary way to ensure the safe operation of the power grid. Under this circumstance, the research of this project has important significance and broad promotion prospects.
