Labview Based Approach For The Design And Development Of Testbed For Coordinated Control And Monitoring Of Multi-energy Smart Grid

In the smart grid, it should focus on micro-mesh part. Microgrid can be developed to promote the efficient use of distributed power, and extends the micro-grid, can be more clean, renewable energy for large-scale convergence. The platform in the distribution process and the traditional power grid is different, it has a distribution in the form of the initiative, which is the traditional transition to a new form of power well the new smart grid.This paper will present the design of a suitable platform for coordinated control strategy, and implement network monitoring software designed micro platform. According to the constraints of each module of wind power systems, photovoltaic systems, energy storage systems that exist, designed to maintain the normal operation of the load level and battery, but the charge and over discharge protection control strategies. The main achievement of the upper and lower monitoring platform machine data and control signal communication functions, data analysis, and design-friendly interactive interface. In order to facilitate the experimenter historical data access and troubleshooting, the platform is also designed using a database for data storage and query capabilities. Details are as follows:(1) Research and Design of “the based on battery state of charge CoordinatedControl Strategy”For each generation in the form of multi-energy generation capacity, power generation opportunity to study, between power and load power,discuss issues of energy distribution for wind turbine and photovoltaic power generation, are classified according to various problems summarize, designed the "battery state of charge based on coordination control strategy, " and verified by simulation whether the control strategy can achieve coordination platform and load electric power generation power homeostasis purposes.(2) Simulation wind turbines power characteristic curve in the PC.Simulated on the host computer fan power, build a wind turbine power generation-wind speed graph, under certain wind conditions, the calculated simulation speed and torque, the simulated wind speed and the torque transmitted to the next crew, lower machine and then transferred to the hardware simulation.(3) Develop for the upper and lower computer communication protocol for thisplatform.For the Lab VIEW platform is carried out on the monitoring, developing upper and lower computer communication protocol for the platform, based on the design of a data communication protocol analysis module, which is responsible for data analysis and extraction of information need to be controlled, the next control command send to a lower position machine through the host computer.(4) Set up the host computer and the database interface module.In order to facilitate long-term control and detection, PC and database connections, the important data stored on the host computer in a database for easy viewing research or data query and analysis of failure occurs.Contents of this paper provides work to promote 973 projects that can be used for laboratory research platform, continue to ensure the smooth progress of 973 issues of great significance.
