Abstract

Based on the renewable portfolio standard and carbon cap-and-trade scheme, consumers faced with the demand of power and carbon emission permits shall be able to participate in three markets, i.e., green power market, electricity market and carbon market. In this paper, we propose a two-step energy trading approach to help consumers optimize their utility, considering the conflict of interest regarding whether to purchase power from the aforementioned three markets and how much power to purchase from each market. This approach takes into account several factors, including the benefits of participating in demand response, the costs associated with consumer dissatisfaction, the costs of power purchased from the electricity market, the costs of renewable power purchased from the green power market, and the costs of carbon emission permits purchased from the carbon market. The two-step formulation establishes an equilibrium problem with equilibrium constraints. A chance-constrained optimization method is utilized due to the uncertain fluctuation of renewable power in the two steps. The equilibrium problem with equilibrium constraints in the two steps can be settled by the nonlinear optimization of multiple subproblems with corresponding Karush-Kuhn-Tucker conditions. Simulations show that the proposed approach is able to significantly improve the utility of the consumers in the energy trading process among green power, electricity and carbon markets.
可再生能源组合标准和碳限额交易计划的最佳能源分享:两步能源交易法
基于可再生能源组合标准和碳排放总量控制与交易计划,面临电力和碳排放许可需求的消费者应能够参与三个市场,即绿色电力市场、电力市场和碳市场。考虑到是否从上述三个市场购电以及从每个市场购电多少的利益冲突,本文提出了一种两步式能源交易方法,以帮助消费者优化其效用。该方法考虑了多个因素,包括参与需求响应的收益、与消费者不满相关的成本、从电力市场购买电力的成本、从绿色电力市场购买可再生能源电力的成本以及从碳市场购买碳排放许可证的成本。两步法建立了一个具有均衡约束条件的均衡问题。由于两步中可再生能源发电量的波动不确定,因此采用了机会约束优化方法。两步中带有平衡约束条件的平衡问题可通过具有相应卡鲁什-库恩-塔克条件的多个子问题的非线性优化来解决。模拟结果表明,在绿色电力、电力和碳市场之间的能源交易过程中,所提出的方法能够显著提高消费者的效用。
