The development of integrated energy system is the only way to realize the energy Internet. The coordinated operation of integrated energy in the region is the key to realize the complementary of electricity

heat and gas. Firstly

the control and operation characteristics of wind turbine

gas turbine and energy storage device are analyzed. Taking the minimum operation cost as the optimization objective and considering the constraints of safety and stability

the comprehensive energy scheduling model of electricity heat gas area is established. Then

the proposed model contains avariety of complex operation constraints of electricity

heat and gas

while the variables are coupled with each other. It means that traditional mathematical optimization methods is difficult to solve this model. Therefore

particle swarm optimization algorithm is used. Finally

the simulation results show that the proposed model and algorithm are correct and effective.
