摘要
分布式经济调度模式因其可靠性高、可扩展性强、通信计算压力均匀等特点而更适用于高渗透率分布式电源接入的场景。但一方面目前分布式经济调度策略存在需获取全局信息的难题,另一方面未考虑到分布式环境下不可避免的个体欺骗行为的问题。该文首先提出基于虚拟发电机的分布式经济调度模式,以微增成本为一致性变量设计了完全分布式经济调度策略,无需提供功率差额和网损等全局性信息。在此基础上,分析了一个甚至多个欺骗个体为提高自身利益而传输带有偏差的一致性变量值对分布式经济调度结果的影响,采用偏差修正方法设计了相应的应对策略。通过多个场景下的仿真计算验证了所提方法的正确性和有效性。
The distributed economic dispatch is more suitable for the future power system with high-permeability of distributed power resource because of its high reliability,strong scalability and even communication computing pressure.However,the current distributed economic dispatch strategies have the difficulty to obtain global information.Moreover,these strategies almost have not taken into account the inevitable individual cheating in the distributed environment.A distributed economic dispatch model based on virtual generator was proposed,and a fully distributed economic dispatch strategy was designed with incremental cost as consensus variable,which does not require global information such as network loss.This paper analyzed the influence of one or more cheating individuals broadcast biased consensus variable values in order to improve their own profits,and designed the corresponding counteract strategy using the deviation correction method.The correctness and effectiveness of the proposed method were verified by simulations in several scenarios.
