Abstract
In order to realize the local consumption of surplus electric energy, this paper proposes a multi-agent cooperative game model of power grid-generator-electrolytic aluminum based on Nash negotiation theory. The operation characteristics of the power grid, generator, and electrolytic aluminum are considered in the modeling of each agent. Then, a cooperative game framework considering electricity trading is further constructed based on Nash negotiation theory. Finally, a series of linearization methods are used to transform the complex problem into the mixed integer linear programming (MILP), which can be effectively solved by commercial solver. In the case studies, based on the actual situation of Yunnan power grids, a comparative analysis of the impact of cooperative and non-cooperative frameworks on multi-agents proves the feasibility of the cooperative game framework. Finally, the cooperative game model is applied to different provinces to verify its universality.
Highlights
As an important industrial electricity load, the highenergy electrolytic aluminum industry is widely distributed in Shanxi and Shandong, rich in coal resources, Southwest China, rich in hydropower resources, and the northwestern region, rich in renewable energy[1]
The main contribution of this paper is to explore the potential of the cooperative game of power grid-generator-electrolytic aluminum based on the needs of national policies
The main contributions are listed as follows: 1) According to national policy guidance needs in China, we propose a multi-agent cooperative game model of power grid-generator-electrolytic aluminum based on Nash negotiation theory
Summary
As an important industrial electricity load, the highenergy electrolytic aluminum industry is widely distributed in Shanxi and Shandong, rich in coal resources, Southwest China, rich in hydropower resources, and the northwestern region, rich in renewable energy[1]. The main contribution of this paper is to explore the potential of the cooperative game of power grid-generator-electrolytic aluminum based on the needs of national policies. We apply this cooperative game model in several provinces with different electricity prices and solar energy. The main contributions are listed as follows: 1) According to national policy guidance needs in China, we propose a multi-agent cooperative game model of power grid-generator-electrolytic aluminum based on Nash negotiation theory. The article assumes that in the cooperative operation framework, generators can sign an agreement with the electrolytic aluminum companies, negotiate to determine the trading power and price, and directly sell electricity to the electrolytic aluminum companies through power grids. The modeling of them is given as follows in sequence
