火储联动技术在源侧调频中的应用

Application of Fire Storage Combined Technology in Source-side Frequency Modulation

在新一代电网的构建中,随着风光新能源高比例并网,电网的输入与输出功率平衡面临严峻挑战,对调频技术的响应速度和准确性提出了更高标准。目前,自动发电控制(AGC)作为主要的调频技术,其核心力量主要依赖于火力发电厂,但由于火力发电的固有特性,其响应惯性问题无法得到彻底解决。为了解决这一难题,提出了将火力发电与储能技术相结合,构建了一种复合调频系统,并为其制定了调节策略模型。通过实际电厂运行数据的模型测试与仿真运算,结果显示,相较于火力发电单独调频,火储联合调频不仅保持了火力发电调频的高里程和输出稳定性,而且显著提升了响应速度和调节精度,使其能更及时、准确地响应电网的调频需求。

In the construction of the new generation power grid,with the high proportion of wind and solar new energy integration into the grid,the input and output power balance of the power grid is facing severe challenges,and higher standards are proposed for the response speed and accuracy of frequency modulation technology.At present,auto-matic generation control(AGC),as the main frequency modulation technology,relies mainly on thermal power plants for its core strength.However,due to the inherent characteristics of thermal power generation,its response inertia problem cannot be completely solved.To solve this problem,it is proposed to combine thermal power generation with energy stor-age technology to construct a composite frequency modulation system,and develop a regulation strategy model for it.Through model testing and simulation of actual power plant operation data,the results show that compared to individual frequency regulation of thermal power generation,the combined frequency regulation of thermal power storage not only maintains high mileage and output stability of thermal power generation frequency regulation,but also significantly improves the response speed and regulation accuracy,enabling it to respond more timely and accurately to the frequency regulation needs of the power grid.
