Energy internet optimization strategy method based on DQN algorithm

The invention relates to an energy internet optimization strategy method. The energy internet comprises a power grid unit, a gas network unit and a distributed cooling heating and power system embedded energy internet unit; the method comprises the following steps: on the premise of ensuring the minimum system operation cost, by coordinating and optimizing the energy internet, excavating the renewable energy utilization rate; performing network optimization configuration, realizing the purpose of rapid dynamic optimization and the self-learning capacity, formulating an energy internet optimization strategy based on the optimal output action, reducing the redundancy of the network as much as possible, and lowering the system operation cost. Under a set control strategy, constraint conditions comprise a load supply and demand balance constraint, a power generation constraint, an output power balance constraint, an energy storage element charging and discharging limit constraint and an external power grid intera
