A numerical approach for macroscopic property simulation in global energy interconnection

The construction of global energy interconnection (GEI) enables to optimally allocate energy resources and protect the environment. Nevertheless, the promotion of GEI is still faced with many practical difficulties and shows a great number of complicated dynamic characteristics. A set of emergencies that may affect GEI is defined and modeled by autoregressive integrated moving average (ARIMA) intervention model in this paper. Then the system dynamics model describing the macroscopic property of GEI is established and the system flowchart is given. Since GEI has high-dimensional nonlinear characteristics, a numerical approach for GEI macroscopic property simulation is proposed. Improved Euler Method is adopted to solve differential and algebraic equations step by step. Effectiveness of the proposed approach is verified by the 911 Event using ARIMA intervention model and macroscopic property simulation of GEI in section IV.
