Planning operation joint optimization method and system for electricity-gas hybrid system based on distributed multiple scenes

[0034] In one or more embodiments, a distributed multi-scenario-based joint optimization method for the planning and operation of an electric-pneumatic hybrid system is disclosed, including the following steps:

[0035] Collect power purchase power, gas source point air intake and net load fluctuation power parameters at time t in different scenarios;

[0036] Establishing a capacity optimization problem model of the electric-gas hybrid system, the capacity optimization problem model of the electric-gas hybrid system includes a capacity configuration layer sub-problem model and a system operation layer sub-problem model;

[0037] Among them, the sub-problem model of the capacity configuration layer aims at the optimal economics of the configuration scheme, and takes the equipment capacity constraint as the constraint condition; the sub-problem model of the system operation layer takes the optimal operation economy and the operation flexibility of the distribution network Optim...
