Design And Implementation Of Photovoltaic Power Generation Control System In Microgrid

Microgrid is very important in the power system,which is mainly responsible for providing on-site power supply for power auxiliary facilities.Photovoltaic power generation is an important power supply mode in microgrid.Remote monitoring and management of photovoltaic power generation system is an important content for power enterprises to realize informatization.The microgrid photovoltaic power generation control system organized and implemented by Sichuan electric power company is studied in this thesis.Based on the photovoltaic power generation control unit deployed on site in microgrid and power communication private network,the system can realize remote control and monitoring of the company’s micro grid photovoltaic power generation system.The research contents and results of this thesis are as follows:(1)By analyzing the management status and problems of micro grid photovoltaic power generation system in Sichuan electric power company,the research and development objectives of the system are determined.The system function development objectives are divided into four aspects: basic information management,operation monitoring management,centralized control management and data report management.The performance objectives are divided into concurrency capability and response time.(2)By the use of software design technology and tools,the functional scheme of the system is designed and analyzed.The functional class structure and timing flow of each module are investigated.The logical structure and data table structure of the database are designed.(3)By the use of.NET platform and C# technology,the system is developed and implemented,the function model of the system is established,and the system is tested,and the expected goal is achieved.Through the application of the system,it can realize the remote monitoring and control management of each microgrid photovoltaic power generation system in the company’s power communication network environment,reduce the working frequency of manual on-site inspection,and improve the real-time and accuracy of management,which has high practical significance.
