摘要

配电网中分布式能源渗透率不断增加，其有效消纳与控制成为新的热点课题。储能和分布式发电系统的结合可以平滑这些间歇电能并网，降低光伏发电对电网的冲击，并提高电网对新能源的接纳能力。鉴于储能发展的必要性以及分布式光伏储能项目面临的成本和经济性问题，建立分布式光伏储能系统全寿命周期的综合效益评估模型。该模型从项目成本、年收益、总利润和静态投资回收期等方面研究了分布式光伏储能系统的经济性，并从配电网改造和备用成本等方面评估了项目的社会整体效益。算例结果表明，分布式光伏储能系统发电自用率高，年净收益增长明显，其经济性对上网电价和度电补贴的依赖较小。随着光伏和储能技术的发展成熟，无储能系统将不再具备经济性优势，分布式光伏储能系统拥有更大的发展潜力。最后，结合国外可再生能源的发展经验，从社会效益回馈用户、电价激励和金融支持等角度提出了政策和激励建议，以促进分布式光伏行业的健康发展。

Abstract

The penetration of distributed energy in the distribution network is increasing

which has caused great pressure to the power grid. The combination of energy storage and distributed generation system can reduce unstable electric energy into the network

reduce the impact of photovoltaic power on the power grid and improve the capacity to accept new energy. In view of the necessity of energy storage and the economic problems of projects

a comprehensive life cycle assessment model was established. This method studies the economy of the system from the aspects of project cost

annual income

total profit

static investment recovery period

and evaluates the social benefits of the project. The example shows that the utilization of power generation is high

the annual net income increases obviously

and its economy is less dependent on the electricity price and the degree of electricity subsidies. With the development of photovoltaic and energy storage

systems without energy storage will no longer have economic advantages

and the photovoltaic energy storage system has greater potential for development. Finally

combined with the experience in foreign countries

suggestions are put forward from the benefit feedback

electricity price incentives and financial support

so as to promote the healthy development of distributed photovoltaic industry.
