【摘要】 我国海岛具有较高开发价值但电网无法覆盖,考虑海岛微网的多能互补特性,为解决确保海岛微网系统的电力装置平稳和高效运行,需要实时获取多能互补系统的运行状态。鉴于此,以本地能源系统输出功率可测为前提,提出一种基于分布式估计理论的多能互补微网系统状态估计器,利用已有的电力通信网络,通过相邻能源系统的信息交互,对分布式能源系统运行状态进行实时估计,从而判断多能互补系统的功率状态。仿真实验结果验证了该方法的有效性。更多还原

【Abstract】 The islands in China are developable and not covered by power grid.Considering the characteristic of hybrid multipleenergy on island.We propose a systematic approach based on distributed estimation to ensure that the electric power device works smoothly and efficiently.We estimate the balance between the distributed generators and the adjusted loads via the communication between the neighboring systems to judge the state of hybrid multiple-energy system based on the communication net.The simulation results verify the effectiveness of the proposed scheme.更多还原
