含风光储微网实验室建设及控制策略研究

Micro-grid with Wind /PV /Storage Laboratory Building and Control Strategy Studying

为了从理论和实验的角度对微网运行特性进行深入研究,建立了包含风机、光伏和储能系统的实验室微网系统。该系统含有两个子微网,能够进行多种运行模式切换模拟和多个微网之间的协调运行仿真,为研究微网的协调控制及运行管理提供了基础平台。研究讨论了微网的主从控制策略和对等控制策略,对比分析了两者的优缺点,并将主从综合控制策略应用于实验室微网系统。通过PSCAD建模仿真以及实验室微网系统平台对控制策略进行了验证。

For the theoretical and experimental point of view to in-depth study of operating characteristics of the microgrid,a laboratory micro-grid system consists of fans,photovoltaic and energy storage systems is established. The system consists of two sub-micro-grid,which can running in varieties of operating mode switching analog and coordination operation simulation between multiple micro-grid,and provides a basic platform for the research of micro-grid control and operation management. The micro-grid master-slave control strategy and peer control strategy are researched and discussed,compared and analysis of the advantages and disadvantages of each other,and used masterslave comprehensive control strategy into laboratory micro-grid system. Finally the control strategy is verified by PSCAD modeling simulation and laboratory micro-grid system platform.
