在全球一致倡导低碳经济的大背景下,源网荷储一体化对助力实现碳达峰、碳中和目标、推动电力系统绿色低碳转型有重要的意义,但示范项目的建设在规划、实施及运营阶段都存在不少难点和痛点.鉴于其重要性,本研究以系统电能量在多时间尺度下的平衡为切入点提供一个全新的框架以讨论源网荷储各要素的科学优化配置:以最大化绿电替代为目标,以场站安全用电及绿电消纳为约束,采用多时间尺度能量平衡算法,在实现项目平稳安全运行的同时,兼顾经济性与电网友好;在实证部分,以大庆油田源网荷储示范项目为案例,验证了该方法的有效性.该方法框架对源网荷储一体化项目的规划配置、新能源开发建设新模式的探索以及规模化储能科技创新等领域提供新的研究思路,对保证电力系统安全稳定运行、探索新能源开发建设新模式、开展规模化储能科技创新等方面具有建设性意义.
A Novel Optimization Approach for the"Power Source-Network-Load-Storage Integration Project"Based on a Multi-Time-Scale Energy Balance Algorithm
Against the backdrop of global consensus on promoting a low-carbon economy,the integration of power source,network,load,and storage is of great significance in helping to achieve carbon peak and carbon neutrality goals,and promoting the green and low-carbon transformation of the power system.However,the construction of demonstration projects has many difficulties and pain points in the planning,implementation and operation stages.In view of its importance,this study took the balance of system power at multiple time scales as the starting point to provide a new framework to discuss the scientific optimization configuration of various elements of source,grid,load and storage:taking the maximum substitution of green electricity as the goal,taking the safe use of electricity and the green electricity absorption of the field stations as the constraint,adopting the multi-time scale energy balance algorithm.While achieving smooth and safe operation of the project,it also takes into account economic efficiency and grid friendliness;in the part of demonstration,the efficiency of this method was verified by the example of the power source-network-load-storage demonstration project in Daqing OilField.The framework provides a novel approach for the planning and allocation of integrated source-network-load-storage projects,the exploration of new modes of new energy development and construction,and the scientific and technological innovation of large-scale energy storage.It has constructive significance for ensuring the safe and stable operation of the power system,exploring new models for the development and construction of new energy,and carrying out large-scale energy storage technological innovation.
