Robust State Estimation Method for Electric-Gas-Heat Integrated Energy System Considering Boundary Equation Constraints

Mengfang GUO Xiang DU Fei WANG

Abstrak

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.
