Integrated Energy Game Planning Considering Uncertainty

With the rapid development of Internet technology and energy conversion devices.The new Internet technology provides a two-way flow between information sources and energy sources.As a result,the coupling of the natural gas network and the power system has enhanced to form an integrated system with two-way flow energy.In the past,simple planning methods for natural gas networks or power systems could not meet the planning needs of integrated energy networks.Therefore,the collaborative planning of the two energy networks has been one of the key research topics.First,based on the robust optimization theory in this paper solves the uncertainty planning problem of integrated energy network.Aiming at the shortcomings of the two-stage robust optimization method,an improved twostage robust optimization method is proposed,which is optimal in the desired scenario and feasible in any scenario.It helps decision makers coordinate system security and economic optimality,providing flexible decision-making solutions.In addition,this paper establishes a fine model for the natural gas network and electro-pneumatic coupling components.The model considers the wind power output and load uncertainty.Based on the improved two-stage robust optimization method proposed above,a collaborative planning model between the power system and the natural gas network is established to optimal economy.Then the Benders decomposition method is used to solve the problem by dividing the model into the main problem and the sub-problem.The effectiveness of the co-planning model of the electro-pneumatic integrated energy system proposed in this paper and the superiority of the two-stage robust optimization method are verified by an example.Considering that the vertically integrated monopoly business model has gradually changed into a competitive online business model.More and more power generation companies compete online,which makes the problem more complicated.Therefore,based on the above-mentioned collaborative planning model based on the uncertainty-based electro-gas integrated energy system,and considering the game between various power generation groups,ie,interest groups,the power of P2 G and gas turbine as energy coupling unit is reconstructed.The gas comprehensive energy planning model aims to maximize the annual net income of each interest group and solve the model through a noncooperative game strategy.Taking the improved electro-gas integrated system as an example,the economics and wind power consumption capacity of each resulting planning solution is analyzed by comparing whether the method considers gaming or not.
