中文摘要:

      送端电网省份一方面需要平衡其内部高速增长的负荷和新能源,另一方面还要满足向外输电的需求。因此,送端电网调节能力的不足使得送、受两端电网的运行经济性和稳定性都受到了挑战。电力需求响应是提高电力系统调节能力的重要手段,能够有效削峰填谷和缓解电力供应紧张。目前我国需求响应工作已经在许多电网受端地区开展,但是我国开展需求响应的送端电网省份还较少。针对上述问题从负荷高速增长、高比例新能源接入、存在电力供应紧张风险和省间电力传输及交易4个方面入手,分析送端电网省份面临的部分问题,探讨开展需求响应的意义和必要性。此外,从市场配套机制发展路径、构建需求响应方案和制定需求响应预案机制3个方面提出一些建议,为送端电网省份需求响应的开展提供借鉴和参考。

英文摘要:

      Provinces of sending- end grids not only need to balance its internal high growth load and new energy resources, but also meet the demand for the external transmission. Therefore, the lack of adjustment ability of the electricity exporting regions challenges the operation economy and stability. Demand response is an important technology to provide more regulation ability for power systems, which can effectively minor the peak- valley difference and relieve the tension of the power supply. At present, demand response in China has been carried out in many electricity importing regions, but the electricity exporting regions carrying out demand response are still few. Aiming at the above problems, the necessity of demand response in electricity exporting regions is analyzed from four aspects：rapid load growth, a high proportion of new energy generation, the risk of power supply shortage, and inter-provincial power transmission and trading. Suggestions are put forward from three aspects：development path of market supporting mechanism, demand response scheme considering regional characteristics, and emergency demand response planning, which can provide advice and guidance for the development of demand response in electricity exporting regions.
