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.
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.
