摘要
随着可再生能源技术的发展,能量管理已经成为微电网研究的关键问题。目前的最优控制策略一般属于集中式控制,而集中控制方案对中央控制器的计算能力以及通信系统要求非常高,使得集中控制策略难以满足微电网系统对于"即插即用"技术的需求。针对上述问题,建立了基于多智能体网络结构的微电网离散系统,以解决上述集中式控制策略存在的问题,同时证明了一致性算法下系统的稳定性和收敛性,提出了基于一致性算法的分布式储能系统的控制策略,以优化储能系统在充放电过程中的损耗。为了提高该模型的准确性,研究还考虑了最佳充电状态的限制,同时验证了分布式储能系统控制策略的可扩展性。
Due to the development of the renewable generation,the energy management becomes a critical issue in the microgrid.Most optimal control methods are based on the centralized control structure.However,the centralized control scheme cannot meet the requirements of the plug-and-play technology of the microgrid system.In order to deal with the problem mentioned above,the discrete system of microgrid based on multi-agent network structure is established.At the same time,the dissertation proves the stability and convergence of the system under the consistency algorithm.To increase the accuracy of the model,the SOC limits are taken into consideration.Furthermore,the control strategy is implemented in the 30-bus system to investigate the scalability.
