电网企业参与的分布式能源运营模式及发展空间研究

Research on business model and development capability of distributed energy with power grid enterprise's participation

运营模式及效益限制分布式能源(distributed energy,DE)项目的良性发展,清洁能源的发展和电力系统改革推动电网公司的角色转型.本文首先对DE市场投资角色进行重组,量化电网企业参与度,以及DE的潜在价值和社会效益,然后针对楼宇型和区域型分布式能源站(distributed energy stations,DES)设计发电模型,通过能量流(冷、热、电)验证联供机组的高效性,最终建立DE能效分享及节能发展空间模型.重点分析输配电改革前后,电网企业不同投资力度对楼宇型和区域型DE项目全生命周期内的节能效益影响,预测电网企业参与的未来发展空间.两类典型DE项目案例分析验证了模型的有效性.

Business model and efficiency limit the benign development of distributed energy(DE)project;the development of clean energy and the power system reform policies have promoted the transformation of power grid enterprise.Firstly in this article,the investors of DE market are restructured,and the participation of power grid enterprise is quantized,so shall also the potential value and social benefits of DE.Then the power generation models whose high-efficiency is verified by energy flow(cold,heat and electricity)are designed for building and regional-based Distributed Energy Stations(DES).Finally,the model of efficiency sharing and development capability of energy-saving is established.Focusing on two situations,before and after the reform of electric power transmission and distribution,the influence of different investment intensity of power grid enterprise on the energy efficiency of building and regional-based DE projects is analyzed within the whole life cycle of DE project,and the trends of energy-saving benefit of DE project with power grid enterprise’s participation is predicted.The efficiency of the proposed method is validated by two typical DE project cases.
