摘要当前农村光伏市场化程度较低，其建设在很大程度上依赖国家扶贫资金的支持。为了加快农村光伏实现自主营收的进程，亟需研究并提出合理的农村光伏市场化交易模式。针对上述问题，以提升农村光伏售电收益和本地消纳水平为目标，提出一种基于价格型需求响应的农村光伏交易模式。首先，分析各交易相关主体的主要行为特征，研究并提出电力用户主动和非主动参与下的交易模式。其次，计及光伏出力特征，提出基于价格型需求响应的光伏发电商定价方法。在此基础上，考虑电力用户主动及非主动参与交易两类情况，并在各类情况下进一步考虑电网公司采用固定电价及峰谷电价两种策略，分别建立电力用户响应行为模型。最后，基于某乡镇光伏扶贫项目的实际数据，开展仿真算例分析，仿真结果验证了所提出交易模式的有效性。

Abstract：At present,the low degree of rural photovoltaic marketization makes its construction rely heavily on the support of national poverty alleviation funds.In order to promote the process that rural photovoltaic achieves independent revenue,it is necessary to propose a proper rural photovoltaic market-oriented trading pattern.To this end,a price-based demand response trading pattern for rural photovoltaic is proposed in this paper to improve photovoltaic sales revenue and local consumption rate.Firstly,the main behaviors of the transaction-related entities were analyzed,and then trading modes under active and non-active participation of users were proposed.Secondly,on account of the characteristics of photovoltaic power supply,the pricing strategy for photovoltaic generators was proposed.On this basis,considering the active and non-active participation of power users in the transactions,and further considering the two strategies which include the fixed price and the peak-valley price that the power grid may adopt,the response model of power users were established respectively.Finally,based on actual data of a photovoltaic poverty alleviation project in a township,simulation was conducted and the results verified the effectiveness of the proposed trading pattern.

Key words： Marketization of distributed generation price-based demand response rural photovoltaic trading pattern
