Abstract:
Aiming at the economic operation of the multiple energy stations system, a method for cooperative optimized operation of multiple energy stations with energy storage station stakeholder based on negotiation game is proposed. Firstly, the energy storage station is introduced into the multiple energy stations system for optimal scheduling decision, and the energy flow relationship and energy conversion relationship of the equipment in the energy station are studied. Meanwhile, a multi-objective optimization model with the best economic performance is established by taking multiple energy stations and energy storage stations as different interest bodies. Secondly, after fully taking into account the energy interaction between different stakeholders, based on the negotiation game theory to coordinate the power interaction value between multiple energy stations and energy storage station and the interests of both parties, a coordinated and optimized operation of multiple energy stations that participate in the scheduling decision model is established. Finally, by taking a typical daily scenario as an example, the scheduling results of the multiple energy stations system in three operating modes and the scheduling results of the existing modeling methods are analyzed. The results show that, compared with the independent operation and interconnected operation of multiple energy stations, adopting the method proposed in this paper can decrease the expense by 17.70% and 4.41%, respectively. Therefore, the optimal economics of the multiple energy station system can be achieved while taking into account the benefits of energy storage stations and ensuring the full consumption of renewable energy, which verify the effectiveness and feasibility of the method.
