Therefore, it is essential to be able to predict its value from historical, measured and forecast data. Based on the assumption that system imbalance is correlated with measured values of system variables as well as predictions of exogenous variables, this work proposes a multi-step version of the autoregressive distributed lag model for the short-term forecast of system imbalance. The proposed forecasting model has been compared with a long short-term memory network-based procedure as well as with an extratree regression model using real data. The results show that the proposed multi-step autoregressive forecasting model outperforms the others in all three evaluation metrics.

On the other hand, actuator faults and communication errors have a considerable influence on the behaviour of the entire networked system. In this paper, an actuator fault diagnosis method is proposed that uses relative output information and it can be implemented without information interchange among the neighbouring subsystems. A subsystem model is proposed for the platoons, based on which the non-measurable states of the neighbouring subsystems can be determined by proper filtering techniques. In addition, the model is also used as the basis for designing a Proportional Integral (PI) observer for actuator fault estimation. Both the pole placement method and Linear Quadratic Estimator (LQE) are explored to determine the observer gain. The simulation results show that the model without network communication produces the same expected behaviour as the one that uses network communication. In addition, the proposed observer can correctly estimate the magnitude of the actuator fault.}, year = {2023} } @inproceedings{MTMT:34573032, title = {Short-Term System Imbalance Forecast Using Autoregressive Distributed Lag Method}, url = {https://m2.mtmt.hu/api/publication/34573032}, author = {Balázs, István and Fodor, Attila and Magyar, Attila}, booktitle = {2023 IEEE 6th International Conference and Workshop Óbuda on Electrical and Power Engineering (CANDO-EPE)}, doi = {10.1109/CANDO-EPE60507.2023.10417995}, unique-id = {34573032}, abstract = {The imbalance between supply and demand is a crucial factor in the operation of the power system therefore, it is essential to be able to predict its value from historical, measured, and prediction data.
