Day-ahead and Intraday Optimal Dispatch Schedule for MGT-IES Considering the Dynamic Characteristics of Main Equipment

The traditional dispatch for micro gas turbine-based integrated energy system (MGT-IES) is mainly conducted based on the static characteristics of the main equipment, which cannot guarantee that the actual output of the system meets its demand. In this paper, the closed-loop dynamic model is introduced to describe the dynamic characteristics of main equipment in MGT-IES and transformed into constraints for dispatch. Furthermore, the day-ahead and intraday scheduling framework based on model predictive control (MPC) method is established to minimize the daily operation and maintenance cost and solved as a mixed-integer linear program (MILP) problem. A case study demonstrates the effectiveness of the proposed day-ahead and intraday dispatch model considering the dynamic characteristics of the main equipment with better matching between demand and actual supply.
