北京市电网气网负荷调节方案研究

The conceptual analysis for regulating the electric power and natural gas network load of Beijing

通过对目前北京冬、夏季天然气和电力季节性负荷曲线进行分析研究,利用其峰谷差较大且互补的特点,以注重经济性和实用性为前提,以改善电网和气网的管网利用率为目标,提出对居民小区现有供暖设备进行改建。冬季使用蓄热电锅炉来辅助燃气锅炉供暖,充分利用优惠低谷电;夏季采用电冷联产系统,在居民区空调用电负荷较高时段辅助供电,并通过暖气管道输送冷水,满足居民对冬季供暖和夏季供冷的需求。

By analyzing and investigating the natural gas and electric power seasonal load curves of Beijing in summer and winter, the paper designs a project to rebuild the old heating equipments in residential district, which is based on practicability and economy and utilizes the big gap between valley and peak and their complementary characteristics. It can improve the utilization ratio of electric power net and pipe network of natural gas. In winter, we use the electric boiler with thermal storage to help the gas power boiler and utilize the preferential electrovalence adequately. In summer, we use the combined cooling and power systems and an auxiliary power supply during high load which is caused by using air condition. We use the heating pipes to transfer the cold water. It can also satisfy the residents＇ demand of heating in winter and refrigerating in summer.
