摘要
智能电网中,功率下垂的控制工作一般都是采用微电网,同时微电网是当前智能电网技术的基础、是可再生能源发电规模化的应用以及新能源开发工作的主要方法手段,不仅能直接有效的做到能源综合利用效率提升,还能当做当前主电网的有效辅助系统,给主电网的可靠性以及供电质量提供了有效保证。为了让微电网电源的电压和频率在运行过程中能够维持稳定,采用当前智能电网中功率下垂控制的实践应用以及怎样利用微电网改变下垂特性斜率的方式来控制智能电网功率下垂进行了探讨,从而提升智能电网的整体稳定性。
In smart grid, power droop control is generally based on micro-grid,which is the foundation of smart grid technology, the main method and means of large-scale application of renewable energy generation and new energy development.It can not only directly and effectively improve the comprehensive utilization efficiency of energy, but also improve the efficiency of energy utilization. It can be used as an effective auxiliary system of the current main power grid, which provides an effective guarantee for the reliability of the main power grid and the quality of power supply. In order to keep the voltage and frequency of micro grid power supply stable during operation, the practical application of power droop control in smart grid and how to control power droop in smart grid by changing the slope of droop characteristic are discussed in order to improve the overall stability of smart grid.
