近年来,上海积极引入外部清洁能源,上海电网消纳我国西南水电规模显著提升,本地电厂开机规模大幅压缩,电网小开机运行成为新常态。区外大规模直流来电不参与调峰、本地机组开机空间集聚压缩,在加大电网调峰压力的同时,更带来了高峰期间发生外来电较大规模失却可能造成上海电网大范围拉限电的重大风险。直流来电的安全消纳成为上海“十三五”期间电力能源利用的关键课题。 In recent years, Shanghai has actively introduced external clean energy. Shanghai Power Grid has greatly improved the scale of hydropower in Southwest China, drastically reduced the power-on scale of local power plants, and turned the power plant into a new normal. Large-scale DC power outside the region do not participate in peak regulation, the local unit to start gathering space compression, while increasing the peak regulation pressure on the grid, but also brought a peak during a larger scale loss of external electricity may cause a wide range of Shanghai Power Grid pulled the power limit The major risks. The safe consumption of DC incoming calls has become a key issue for the utilization of electric energy in Shanghai during the “13th Five-Year Plan” period.
