【摘要】：实现能源的清洁替代和电能替代已成为我国能源发展的必然趋势,然而由于新能源的随机性与波动性使得其并网消纳成为一大难题。日益增大的电力负荷峰谷差不仅严重威胁了电网安全、经济地运行,还增加了发电企业的投资成本与运行成本,而电力用户可以通过改变用电行为调节电力系统负荷。实施需求响应能够鼓励电力用户根据电价信号,主动减少或增加用电的强度,只要电力用户的响应电量能够均衡新能源的并网电量、响应速度能够应对新能源的功率变化,就能够在促进电力的供需平衡的基础上促进新能源消纳。本文以工业用户为研究对象,旨在提出一种能够促进工业用户参与需求响应项目、并在需求响应过程中尽可能多地消纳新能源的激励机制。为此,首先全面梳理了国内外学者在需求响应领域的研究成果,并对我国新能源开发利用概况、需求响应相关理论以及系统动力学相关理论进行了阐述。其次,在掌握我国工业用户需求响应现状的基础上,对钢铁行业、机械行业、有色金属行业与化工行业等重点工业行业的用电特点及负荷特性进行了深入分析,得出了其需求响应潜力以及影响其参与需求响应项目的影响因素,并探讨了工业用户在需求响应过程中参与新能源消纳的可行性。然后,通过绘制工业用户、电网公司、发电企业与政府部门四个参与主体之间的利益联动关系分析图,提出外部激励补贴与内部效益共享并驾齐驱的激励机制,并选取需求响应用户参与度、可避免峰荷比例等评价指标,借助Vensim软件构建了需求响应项目仿真分析方程。最后,以吉林地区工业用户为仿真分析对象,分无外部激励补贴无内部效益共享、有外部激励补贴无内部效益共享以及无外部激励补贴有内部效益分享三种情景进行模拟,使激励机制得到了进一步的完善,并评估了需求响应项目不同情景下的实施效果,提出针对性的对策建议。
[Abstract]:The realization of clean energy substitution and electric energy substitution has become the inevitable trend of energy development in China. However, due to the randomness and volatility of new energy, it becomes a difficult problem to connect to the grid. The increasing power load peak and valley difference not only seriously threatens the security of power grid, but also runs economically. It also increases the investment cost and operation cost of the power generation enterprise, and the power user can adjust the load of the power system by changing the power consumption behavior. The implementation of the demand response can encourage the power user to actively reduce or increase the intensity of the electricity according to the electricity price signal. As long as the response capacity of the power user can balance the grid-connected power of the new energy source, the response speed can cope with the power change of the new energy source. In order to promote the balance between supply and demand of electric power, the new energy consumption can be promoted. In this paper, we take industrial users as the research object and propose a project to promote the participation of industrial users in demand response. And in the process of demand response as much as possible to absorb the incentive mechanism of new energy. For this reason, the first comprehensive review of domestic and foreign scholars in the field of demand response research results, and the development and utilization of new energy in China. The theory of demand response and the theory of system dynamics are expounded. Secondly, on the basis of mastering the current situation of industrial customer demand response in China, the iron and steel industry, machinery industry, The characteristics of power consumption and load characteristics of key industries such as non-ferrous metal industry and chemical industry are analyzed in depth. The demand response potential and the factors influencing its participation in demand response projects are obtained. The paper also discusses the feasibility of industrial users participating in new energy consumption in the process of demand response. Then, by drawing the analysis chart of the relationship between the four main bodies of industrial users, power grid companies, power generation enterprises and government departments, In this paper, the incentive mechanism of external incentive subsidy and internal benefit sharing is put forward, and the evaluation indexes such as demand response user participation, peak load ratio can be avoided are selected, and the simulation analysis equation of demand response project is constructed with the help of Vensim software. Finally, the simulation analysis equation of demand response project is constructed with the help of Vensim software. Taking the industrial users in Jilin area as the simulation object, there are three kinds of simulation scenarios: no external incentive subsidy, no internal benefit sharing, no external incentive subsidy, no internal benefit sharing, and no external incentive subsidy and no internal benefit sharing. The incentive mechanism is further improved, and the implementation effect of the demand response project under different scenarios is evaluated, and corresponding countermeasures and suggestions are put forward.
