Aimed at spatio-temporal correlation of natural gas line-pack

it is significant to use multiple time scale and model predictive control. Considering the slow dynamic characteristics of natural gas pipeline network and the time interval coupling effect of transient variables of natural gas system

a multiple time scale optimal scheduling strategy based on model predictive control is proposed

which makes the control process of computing the active power outputs and gas production by gas resource more smoothly. And then

taking the active power output and gas production obtained by day-ahead scheduling as reference values

the multi-step rolling optimization based on model predictive control is carried out in intra-day scheduling. Finally

the modified IEEE 24-node power system and the Belgian 20-node natural gas system are used to verify the feasibility and effectiveness of optimization scheduling strategy

and the influences on the operation of the integrated power and gas energy systems of natural gas line-pack are analyzed.
