Research And Application Of Coordinated Control System In Park Micro Grid

With the continuous expansion of the power grid,the demand for the microgrid will increase accordingly.Nowadays,microgrids are being used in commercial and industrial areas,urban areas and remote areas.With the development of computer technology and communication equipment,microgrids gradually move into the field of intelligence through the combination of computer technology,control technology and algorithm strategy.Micro-grid is emerging as an emerging power system,to make up for the shortcomings of the traditional power grid.Therefore,the research on microgrid has great significance for the development of power grid.First of all,the development of microgrid and its coordination control technology are reviewed.The research status of microgrid and coordinated control technology at home and abroad are introduced in detail.In view of the current development trend of microgrid coordinated control,the method of system operation control of microgrid is proposed.Secondly,the coordinated control strategy of the master-slave control micro-grid is planned.Each coordinated control strategy is studied in detail,and the steps of each strategy are given in combination with the flow chart.Then,the overall design scheme of the microgrid coordinated control system software is proposed,the data communication mode of the microgrid coordinated control system is discussed,and the common communication protocol is selected.The logical sequence and the realization process of the system software function module are expounded,and the function module is illustrated through the core code of the function.The overall plan of Web server software is planned and designed,and various functional modules in the software are developed.Corresponding Web pages are designed and implemented according to the functional requirements of the system.Finally,under the condition that the software development of the micro-grid coordinated control system is completed,the system test environment is set up based on the actual environment of a company's industrial park,and detailed test cases are designed to verify the function of the coordinated control system and controller The results show that the coordinated control function can switch the state of the microgrid freely,and meet the demand of the microgrid uninterrupted power supply and economic operation.
