【摘要】：为提高新能源微电网电力供应的安全性和经济性,提出了一种基于Multi-Agent和Petri-net技术的协调控制策略。微电网是一个典型的混合系统,包括多种分布式发电和储能单元,它们具有不同行为特征和多种运行模态。考虑到这些分布式单元模态运行和逻辑切换的复杂性,构建了Multi-Agent系统(MAS),通过多Agent的交互作用来实现分布式协调控制策略。由于Petri-net模型是表述多模态运行系统的最有效工具之一,所以采用petr-net模型来描述各分布式单元的模态切换行为并以此设计其单元Agent模态切换控制策略。在此基础上,基于Multi-Agent系统框架在上层中心Agent中构建各分布式能源单元之间的模态协调切换控制策略,来实现整个微电网运行模态的有效切换。最后仿真验证了所提出的控制策略的有效性。
[Abstract]:In order to improve the security and economy of power supply in new energy microgrid, a coordinated control strategy based on Multi-Agent and Petri-net technology is proposed. Microgrid is a typical hybrid system, including a variety of distributed generation and energy storage units, they have different behavior characteristics and a variety of operating modes. Considering the complexity of mode running and logic switching of these distributed cells, a Multi-Agent system is constructed to implement distributed coordinated control strategy through the interaction of multiple Agent. Because the Petri-net model is one of the most effective tools to describe the multimodal operation system, the petr-net model is used to describe the modal switching behavior of each distributed cell and to design its Agent modal switching control strategy. On this basis, the modal coordination switching control strategy among the distributed energy units is constructed in the upper central Agent based on the Multi-Agent system framework to realize the effective switching of the operation modes of the whole microgrid. Finally, the effectiveness of the proposed control strategy is verified by simulation.
