| 中文摘要: |
| 受春节期间负荷整体水平较低的影响，江苏电网火电机组开机数量较少，电网调峰、调差困难。同时春节用电低谷时段恰好也是风电、光伏等新能源发电的旺盛时段，新能源发电被迫低功率运行参与电网调差，不利于新能源的及时、充分消纳。为解决春节期间电网调差及新能源消纳难题，江苏电网于2018年春节期间（2月16—18日）组织了省内首次“填谷”需求响应。单次最大响应负荷为168万kW，3日累计响应负荷928万kW，有效缓解了电网调峰、调差压力，保障了本地区新能源发电的全额消纳。 |
| 英文摘要: |
| Under the influence of low-level load during the Spring Festival, the thermo electric generating set of Jiangsu grid fails to open enough thermal generators, leading to the difficulty in regulating peak and valley load. The valley load period during the Spring Festival is just the period when renewable energy, such as wind and photovoltaic, reaches its peak in generating power, renewable energy generation is forced to participate in regulating the load at a low capacity, adding a negative effect on the full utilization of renewable energy. To deal with the above problems, State Grid Jiangsu Electric Power Company organized the first provincial “valley shaft”demand response during the Spring Festival (Feb.16th-18th), providing the load of 1.68 million kilowatts at one time and 9.28 million kilowatts in total. This action efficiently alleviates the pressure on regulating the power load, assuring the full utilization of the renewable energy generation in this region. |
