摘要/Abstract

摘要： 针对电-气-热综合能源系统（integrated energy system，IES），建立了非高斯测量噪声下的量测-状态方程。考虑耦合元件边界条件，将其既作为等式约束又作为虚拟量测方程，基于极大似然鲁棒状态估计方法，提出了一种考虑边界等式约束的电-气-热IES鲁棒状态估计方法。在高斯和非高斯噪声下，进行仿真验证。仿真结果证明：所提方法可为IES在线分析和优化调度提供准确的全局状态感知。

Abstract: A measurement state equation was established for the integrated energy system (IES) of electricity gas heat under non Gaussian measurement noise. Considering the boundary conditions of coupled components, which serve as both equality constraints and virtual measurement equations, a robust state estimation method for electrical pneumatic thermal IES considering boundary equality constraints is proposed based on the maximum likelihood robust state estimation method. Conduct simulation verification under Gaussian and non Gaussian noise. The simulation results demonstrate that the proposed method can provide accurate global state awareness for online analysis and optimization scheduling of IES.
