| 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: |
| This paper proposes a coordinated control strategy based on Multi-Agent and Petri-net technology to improve the security and economy of the new energy micro-grid’s electricity supply. The micro-grid is a typical hybrid system that includes many sorts of distributed energy resource units with different behavioral characteristics and multiple operational modes. Considering the complexity behind multi-mode behaviors, a Multi-Agent System is firstly constructed to implement distributed coordinated control strategy. Then, by using Petri net model, the multi-mode switching behaviors of the distributed energy resource units are described and the control strategies of their unit Agents are designed respectively. It is because that Petri net is one of the most useful tools for modeling the multi-mode system. On this basis, the coordinated control strategies are designed based on the Multi-Agent System platform. The effectiveness of the proposed control is demonstrated through simulation examples. |
