摘要
随着新能源技术的不断成熟,新型能源在未来能源结构中的比例将会越来越大,发展前景良好。在售电侧进一步开放的背景下,为增强客户粘性,争取潜在客户,电网企业提出了光伏增值服务的概念。将光伏售卖商、电网公司以及光伏增值服务消费者作为研究的主体,采用Stackelberg博弈法建立了包含3个主要参与方在内的关于光伏增值服务系统的双层定价模型,提出了基于最佳收益的光伏增值服务定价方法。同时,对河南光伏园区的实际情况进行了研究分析,建立了该地区“自发自用,余电上网”的Stackelberg双层博弈定价模型,确定了该模式下的最优定价。最后,运用两经济性评价指标对该地区采用“自发自用、余电上网”服务模式下的经济效益进行了评价和总结。结果表明,用户在购买此种光伏增值服务后,不仅可以享受光伏发电这种清洁能源,同时通过向电网出售余电还节约了购电成本,逐渐收回成本甚至盈利。
With the development of new energy technology,the new-type energy will occupy increasingly larger proportion of the future energy structure,and the development prospect is bright.Under the policy background of further opening the sales side,the concept of photovoltaic(PV)value-added service is proposed to enhance customer stickiness and gain potential customer of power grid enterprises.Using Stackelberg game method,the pricing model of double PV value-added service system is established including three main game participants,that is,the PV seller,grid company and PV value-added service consumers as the research subjects,and the pricing method of PV value-added services is put forward based on the best benefits.At the same time,the actual situation of Henan PV park is studied and analyzed.The Stackelberg double-deck game pricing model for"spontaneous self-use and surplus PV power selling to grid"in the region is established,and the optimal pricing in this mode is determined.Finally,two economic evaluation indexes are used to evaluate and summarize the economic benefits of"spontaneous self-use and surplus PV power selling to grid"service mode.The results show that the users after buying the PV value-added services,not only can enjoy the clean energy of PV power generation,but also save electricity purchasing cost,and by selling surplus power to grid,gradually recover costs or even make a profit.
