上海电源结构优化策略研究

Research on Optimization Strategy of Power Supply Structure in Shanghai

目前上海负荷峰谷差日益增大,市外来电规模增加及新能源优先消纳等问题要求上海电源装机具有较强的调峰灵活性。该文系统地分析了上海用电负荷特性,并从增强调峰灵活性角度出发,对上海电源结构优化策略和实施方案进行了详细分析。研究结果表明未来上海市内电源装机建设应以建设增加燃气机组,提高灵活调峰性能为主。上海缺口容量的燃机替代燃煤机组方案策略包括退役煤机原址建设燃机,以及城市外围规划燃机电源点。现有小型煤机中,石洞口发电厂具备原址燃机替代条件。金山、青浦、嘉定、浦东4个区域适宜新增燃机替代燃煤机组。

The increasing peak-valley load difference,the increasing scale of external power and the priority of new energy consumption in Shanghai required the flexibility of peak load regulation.In this paper,the characteristics of Shanghai power load were analyzed systematically,and the optimization strategy and implementation scheme of Shanghai power supply structure were analyzed in detail from the perspective of enhancing the flexibility of peak load regulation.The results show that the installation of power supply in Shanghai in the future should focus on increasing gas turbine generating unit and improving peak load regulation performance.The strategy of replacing coal-fired generating units with gas turbine for Shanghai's gap capacity consists of the construction of gas turbine at the original site of retired coal machine and the planning construction of gas turbine power points in the city's outskirts.Shidongkou power plant had the construction condition of gas turbine at the original site of existing small coal-fired power plants.Jinshan,Qingpu,Jiading,and Pudong are suitable for the new gas turbine construction.
