电力现货市场下激励型需求响应交易机制及出清模型

为了进一步推动中国电力现货市场的建设,考虑发电侧和负荷侧共同参与、公平竞争的市场化交易模式将是电力现货市场未来发展的趋势。鉴于国内现货市场需求响应的研究尚处于起步阶段,需求响应产品如何参与市场是亟待解决的问题,对此设计了一种适用于目前国内电力现货市场的计及激励型需求响应的交易机制和出清模型。首先分析了批发市场下激励型需求响应的参与方式,探讨相关的交易机制和响应效益评估方法;然后,根据参与用户的市场投标信息构造激励型需求响应的现货市场竞价模型,在能量与备用市场联合优化模式下提出计及激励型需求响应的市场出清模型。最后,通过IEEE-30节点算例对激励型需求响应的市场效益进行定量化分析,验证了所提方法的实用性和模型的有效性。

Trading Mechanism and Clearing Model of Incentive Demand Response in Electricity Spot Market

In order to further promote the construction of electricity spot market in China, it is the future development trend of the power spot market to operate on the market-oriented trading mode, in which the power generators and loads participate together and compete fairly. Base on the fact that the research on the demand response (DR) of spot market is still in its infancy in China, and how to participate in the market for DR is an urgent problem to be solved. This paper proposes a new market trading mechanism with clearing mode that takes into account the incentive demand response (IDR). Firstly, an intermediate agent approach has been introduced to integrate IDR resources as one to participate in the wholesale market for dealing with the distributed characteristics. Next, an adaptive IDR trading mechanism has been discussed with the development of electricity spot market in China, and an effective benefit evaluation method for clear spot market has been analyzed for IDR. After that, the bidding model of IDR in the wholesale market is constructed according with the providers’ bids, and the day-ahead and real-time market clearing model with IDR is designed in the joint optimization mode. Finally, the effectiveness of the proposed method and model is verified by the quantitative analysis of the market benefit of IRD through the IEEE 30-node system.
