| 摘要: |
| 约定电力曲线的交易方式能为交易双方提供更多选择，避免中长期电量合同分解问题，细化电力交易的时间粒度，有利于中长期市场与现货市场的衔接。为此，提出一种面向需求侧的约定曲线形状及价格的曲线交易机制。在此基础上，考虑电力交易中心和售电公司两个利益主体，构建曲线交易机制设计双层优化模型。其中上层以电力交易中心平衡账户在结算周期内余额方差之和最小为目标，构建曲线交易机制关键参数优化设计模型。下层考虑了售电公司的购电策略、可中断负荷购买策略和储能租赁策略，构建以单个售电公司利润最大化为目标的经营决策模型。算例结果表明所提出的曲线交易机制设计双层优化模型能有效反映电力交易中心参数设置对售电公司经营策略的影响，为电力市场机制设计提供定量分析的依据。 |

| Abstract: |
| The transaction mode of a power curve agreement can provide more choices for both parties, avoid the problem of contract decomposition in the medium and long-term electricity market, and refine the time granularity of power transaction. This facilitates the connection between the medium and long-term electricity market and the spot market. To this end, a curve trading mechanism oriented to the demand-side that agrees curve shape and price is proposed. Then, considering the two stakeholders of the power trading center and the electricity retailers, a two-layer optimization model for the design of the curve trading mechanism is constructed. In the upper layer, to minimize the sum of the variance of the balance account of the power trading center in the settlement period, an optimization design model of the key parameters of the curve transaction mechanism is constructed. In the lower layer, with the power purchasing strategy, interruptible load purchasing strategy and energy storage leasing strategy of the electricity retailers are considered, and a management decision model to maximize the profit of a single electricity retailer is constructed. The results of the case studies show that the proposed two-layer optimization model for the design of the curve trading mechanism can effectively reflect the influence of the parameter setting of the power trading center on the management strategy of electricity retailers, and provide the basis for quantitative analysis of the power market mechanism design.
