Abstract

The invention discloses a regional integrated energy system optimization scheduling method and device based on a Stackelberg game, and the method comprises the steps of issuing an electricity price signal with economic benefit maximization as an optimization objective function according to a system manager, and feeding back a thermoelectric load with operation cost minimization as an optimization objective function by a user; in response to the obtained user feedback thermoelectric load, enabling the system manager to judge whether to update an electricity price signal based on a thermoelectric load demand-electricity price sensitive relationship; if the system manager judges that the electricity price signal is not updated, enabling the system manager to send a production control instruction to the capacity base; in response to the acquired production control instruction, enabling the capacity base to judge whether the wind power integration power reaches a target value or not; and if the capacity base judges that the wind power integration power does not reach the target value, controlling the system manager to update the electricity price signal. The wind power integration power can be obviously improved by adopting a Stackelberg game optimization strategy, so that the wind power integration demand of a productivity base is ensured.

Description

technical field

[0001] The invention belongs to the technical field of integrated energy systems, and in particular relates to an optimal scheduling method and device for a regional integrated energy system based on the Stackelberg game. Background technique

[0002] The regional integrated energy system is an emerging concept that accompanies the emergence of the Energy Internet. The regional integrated energy system uses electric power as the hub to realize multi-energy coupling and conversion, promote energy cascade utilization and new energy consumption, and has good development prospects and positive research significance.

[0003] The optimal scheduling of regional integrated energy systems is a collaborative problem of multiple stakeholders at the level of "source-network-load-storage". interest demands, which makes the balance optimization effect of multi-subject interests poor. Contents of the invention

[0004] The present invention provides a Stackelberg game-...
