一种考虑多能源互补的电力系统经济调度方法

An Economic Dispatching Method for Power System Considering Multi-Energy Complementarity

可再生能源并网后,大量配套的电力电子设备和电能传输过程中的有功与无功损耗使得电力系统的运行稳定性及经济性受到影响。针对可再生能源并网后电力系统的经济调度问题,对不同模型的优缺点进行评述和讨论,并基于分段线性化与混合整数线性规划(Mixed Integer Linear Programming,MILP),提出一种考虑多能源互补的机组组合优化方案,以提高能源供需协调能力,推动能源清洁生产和就近消纳,提高电力系统的经济性。

After the renewable energy is connected to the grid,the operation stability and economy of the power system are affected by a large number of supporting power electronic equipment and the active power and reactive power loss in the process of power transmission.Aiming at the economic dispatch of the power system after the renewable energy is connected to the grid,the advantages and disadvantages of different models are reviewed and discussed.Based on piecewise linearization and Mixed Integer Linear Programming(MILP),a new method considering multi-energySource complementary unit combination optimization scheme to improve the coordination of energy supply and demand,promote clean energy production and nearby consumption,and improve the economy of the power system.
