Multi-Time Scale Optimal Operation Method of Independent Island Zero-Carbon Microgrid
摘要
Abstract
Aiming at the problem of sustainable supply of energy resources in traditional islands,a multi-time scale optimal operation method of independent island zero-carbon microgrid is proposed to meet the requirements of stability,flexibility and economy of independent island microgrid.Firstly,according to the actual situation of island energy consumption,the wind-solar-storage-hydrogen-water system model of independent island zero-carbon microgrid is constructed.Secondly,considering that hydrogen energy storage has the ability of long-term energy storage,a multi-time scale optimization model spanning week-ahead,day-ahead,and intra-day is established,and a multi-time scale operation scheduling strategy considering wind and solar uncertainty is proposed.In the week-ahead stage,the trend of wind and solar resources is predicted based on historical data,and the start-stop plan of hydrogen energy storage is formulated.In the day-ahead stage,the stochastic optimization method based on multi-scenario technology is used to deal with the uncertainty of wind and solar energy and formulate the start-stop plan of seawater desalination unit.In the intra-day stage,the operation status of the hybrid energy storage and seawater desalination system is dynamically adjusted in combination with real-time wind and solar data.Finally,the simulation results show that the proposed method can better utilize the characteristics of hydrogen energy storage for a long time to store energy and promote the system's wind and solar consumption.When the wind and solar resources are insufficient,it can effectively reduce the load loss and improve the reliability of the independent island zero-carbon microgrid system.关键词
