Method and device for optimal dispatching of regional integrated energy system based on stackelberg game

Abstract

The invention discloses a stackelberg game-based regional comprehensive energy system optimization scheduling method and device. The method includes: according to the power price signal issued by the system manager with the optimization objective function of maximizing economic benefits, user feedback takes the minimization of operating costs as the optimization objective The thermoelectric load of the function; in response to the obtained user feedback thermoelectric load, based on the sensitive relationship between thermoelectric load demand and electricity price, the system manager judges whether to update the electricity price signal; if the system manager judges not to update the electricity price signal, the system manager sends a Production control instructions; in response to the obtained production control instructions, the production base judges whether the wind power grid-connected power has reached the target value; if the production base judges that the wind power grid-connected power has not reached the target value, the control system manager updates the electricity price signal. In the strategy of using Stackelberg game optimization, the wind power grid-connected power can be significantly increased, thus ensuring the demand for wind power grid-connected production bases.

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-...
