摘要
集中式优化方法难以应对未来电网柔性负荷广泛渗透以及电力元件"即插即用"的技术要求。区别于集中式经济调度,提出一种电力系统分布式经济调度策略。应用多智能体系统中的一致性算法,以发电机组的增量成本和柔性负荷的增量效益作为一致性变量,设计一种用于电力系统经济调度的算法,通过分布式优化的方式求解经济调度问题。算例仿真与分析验证了所提调度策略的有效性。
The centralized optimization methods could not cope with the widely-permeated flexible loads of future power grid and meet the requirements for the ＂plug-and-play＂ of power equipment,different from which,a strategy of distributed economic dispatch is proposed. An algorithm based on the consensus algorithm of multi agent system is designed to solve the economic power dispatch problem by the distributed optimization,which takes the increment cost of generation unit and the increment benefit of flexible load as the consensus variables. Case simulation and analysis show the effectiveness of the proposed strategy.
