Embodiment 1
[0102] This embodiment proposes a centralized transaction optimization decision-making method for regional comprehensive energy systems. This embodiment first establishes the energy trading framework of the regional comprehensive energy system. Considering that each sub-energy system is interconnected through the distribution network, the distribution network is involved as an MA, forming a master-multiple-slave energy transaction relationship with each sub-energy system.
[0103] Secondly, aiming at this transaction relationship, a master-slave game mathematical model between MA and each sub-energy system is established. As a party to the operation transaction, MA has the priority to set the price. Therefore, MA sets the purchase and sale electricity price as the leader, and the sub-energy system responds to the electricity price as a follower. The two can form a Stackelberg master-slave game.
[0104] Then, based on the master-slave game model, the MA electricity price opti...
Embodiment 2
[0190] In this embodiment, the transaction optimization decision-making method proposed in the above-mentioned embodiment 1 is applied to a certain regional comprehensive energy system to provide auxiliary decision-making for its energy utilization rate.
[0191] The regional integrated energy system of this embodiment includes three sub-energy systems, based on which an intermediate agency MA is established. Each sub-energy system has its own energy supply and energy storage equipment, and each sub-energy system is connected to the external power grid and natural gas network through tie lines. Sub-energy system i combines its own operating conditions to trade with MA to reduce operating costs; MA purchases electricity from the electronic energy system at a low price at time t through the price difference between the purchase and sale of electricity, and sells it to the electronic energy system at a high price. Finally, MA and The large power grid settles unbalanced electricit...
