基于母线频率信号的独立微网多源协调控制策略
摘要：为了实现独立微电网的长期稳定运行,本文针对小型的独立微电网,提出了基于母线频率信号的多源协调控制策略和独立微电网的自我决策模型,本文提出的协调控制策略中,依据母线频率信号算法,在考虑储能系统荷电状态的基础上,设定频率阈值,微型燃气轮机将其作为控制模式切换信号,根据储能系统的荷电状态配合协助储能系统运行,保证储能系统能量充足,实现了快速响应的储能系统与后备电源微型燃气轮机之间不依赖通信的多源协调控制。通过MATLAB/SIMULINK仿真平台的验证,所述协调控制策略具有较大优势,可维持独立微电网的稳定运行。
Abstract:To achieve long term and stable operation of standalone microgrid, the multi source coordinated control strategy based on bus frequency signal and self decision model of the standalone microgrid are put forward in this paper. As to the proposed coordinated control strategy, according to the bus frequency signal algorithm, the frequency threshold is set up by considering the state of charge of the energy storage system, which is used as the switch signal of control mode in the micro turbine. The energy storage system operate according to the state of charge of the energy storage system, which can guarantee sufficient energy for energy storage system, and realizes cooperative control between the active storage system and the back up micro turbine independent of communication. Through the verification on MATLAB/SIMULINK simulation platform, it can be seen that coordinated control strategy has good effects, and can maintain the stable operation of the standalone microgrid.
