Photovoltaic, energy storage and charging pile integrated charging station is a high-tech green charging mode that realizes coordinated support of photovoltaic, energy storage and intelligent charging. In this paper, a control model of each part of comprehensive charging station considering the benefits of users and charging stations is established. A heuristic algorithm is used to solve the benefits under the cooperative control strategy of comprehensive charging station, and a new collaborative control method is proposed. In addition, income sensitivity and other indicators are designed to quantitatively analyze the relationship between the total revenue, quantity and subsidies of electric vehicles under the coordinated control strategy of integrated charging station. Can support the power company integrated charging station project.

Due to the volatility, randomness and seasonality of the load, there is no effective prediction model for the load development trend after the large-scale "coal to electricity" access to the rural distribution network, which affects the capacity planning of the rural distribution network. Aiming at this problem, this paper deeply analyzes the load characteristics and influencing factors of "coal to electricity" in rural areas, puts forward a screening method of single forecasting model based on grey correlation degree and effectiveness index, establishes the optimal medium and long-term combined forecasting model of "coal to electricity" load, and puts forward the flow chart of forecasting model. Finally, an example based on the historical data of a typical "coal to electricity" area is given to verify the results. The results show that the combined forecasting model can further improve the accuracy of the medium and long-term load forecasting results of "coal to electricity" through dynamic weighted optimization of the combined forecasting results.
Distribution network planning big data analysis platform is a software used to assist in planning and design. It is used to improve the efficiency of data query, processing, analysis and statistics. The platform has the functions of automatic verification, upload and download of basic data details, automatic summary of planning outline, automatic generation of main index table of city and county distribution network, and visual display of distribution network.Through the vertical penetration of overall analysis, power grid scale, power supply quality, power grid structure, equipment level, power supply capacity and other indicators, the query, statistics and display of detailed data and operation indicators of provincial, municipal and county power grids are achieved.

From the perspective of harmonic constraints, this paper analyzes the access capacity and access mode when the distributed generation is connected to the power grid, and puts forward the mathematical model for calculating the maximum access power of the distributed generation. Combined with a typical chain distribution system, matlab simulation calculation and FFT harmonic analysis are carried out, so as to obtain the maximum access power of the distributed generation at each point along the feeder when a single distributed generation is connected. It is of great significance to reasonably plan the distributed access location and access capacity in practical engineering.

In view of the immature control system of permanent magnet brushless DC motor and the instability of the control system, this paper proposes a permanent magnet brushless DC motor based on phase advance correction controller, designs the controller to realize the closed-loop automatic control of the system, and proves the effectiveness of the control strategy through modeling and simulation, so as to solve the instability of the control system.
The national development and reform commission proposed to pilot promote the large-scale development of distributed photovoltaic in the whole village, town and county, and pointed out that promoting the pilot of large-scale development of distributed photovoltaic in the whole county is an important measure to implement the strategic goal and task of "carbon peak and carbon neutralization".In order to carry out in-depth analysis and research on the impact of roof distributed photovoltaic construction in the whole county, provide suggestions and decisions for the company and Energy Bureau to promote roof photovoltaic construction, this paper This paper takes village level roof photovoltaic as the research object, carries out research from the aspects of village overview, photovoltaic access overview, load and electricity of village, photovoltaic income and impact of photovoltaic access on Power Grid.
