摘要
微电网电源的随机性和不确定性对微电网的可靠运行产生很大影响。综合考虑风光储微电网的运行特性,提出了基于态势预测的微电网运行框架,对微电网中的风力机进行基于BP神经网络的态势预测,确定风力机未来时刻的运行状态,然后建立风光储微电网模型,最后对基于态势预测的微电网进行仿真模拟。结果表明,基于态势感知理论的微电网运行控制比正常运行的微电网更稳定。
The randomness and uncertainty of microgrid power supply have a great impact on the reliable operation of microgrid.Comprehensively considering the operating characteristics of the wind and solar storage microgrid,a microgrid operation framework based on situation prediction is proposed.First,the situation prediction of the wind turbines in the microgrid based on the BP neural network is performed to determine the future operation status of the wind turbines,and then the wind and solar storage microgrid is established.Model,and finally simulate the microgrid based on situation prediction.The results show that the microgrid operation control based on the situational awareness theory can operate more stable than the normally operating microgrid.
