Multi-energy complementary and coordinated operation is one of the most important technologies for the integrated energy system to achieve optimal operating economic benefits. In order to solve the operation optimization problem of the electricity-gas integrated energy microgrid with the intermittent renewable energy

an integrated energy microgrid operation optimization method based on the deep deterministic strategy gradient was proposed. First

this method uses the energy hub method to mathematically model the electricity-gas integrated energy microgrid

and adds necessary constraints to various energy equipment. Then

the integrated energy microgrid optimization scheduling problem is transformed into a Markov decision process

and the system is reasonably defined state

action

and reward. This method takes the optimal economic benefit as the objective function

by training the agent to interact with the environment

it uses continuous action to coordinate multiple energy to form an optimal scheduling strategy. The calculation results of actual calculation example show that

this method can solve the operation optimization problem of the electricity-gas integrated energy microgrid more reasonably and effectively

the calculation time is short

so it has higher practical application value which meets the demand for energy saving and cost reduction of the integrated energy microgrid.
