微电网兼容各种分布式电源,能够实现自我控制、保护和管理,提供安全、可靠、灵活的电力供应,通过整合经济高效的发电机组实现较好的经济效益。但微电网经济效益一直没有得到充分认识,多智能体(Multi-Agent)技术对于微电网的优化经济运行研究具有重要价值。首先介绍了Multi-Agent的基本原理,提出了基于由微电网Agent,分布式电源Agent,外部配电网Agent,终端用户Agent以及调度中心Agent等组成的Multi-Agent的微电网优化经济运行框架,从购售电交易、调峰服务、降低线损等3个方面分析了微电网的经济效益,并建立了微电网系统优化经济运行模型。选取具体的微电网设计案例,求解出该算例的优化经济运行效益,证实了基于Multi-Agent的微电网系统优化经济运行模型的正确性和有效性。
Micro-grids are compatible with a variety of distributed power supplies that enable self-control, protection and management to provide a secure, reliable and flexible power supply that achieves better economics by integrating cost-effective generators. However, the economic benefit of microgrid has not been fully recognized. Multi-Agent technology is of great value for the study of optimal economic operation of microgrid. Firstly, the basic principle of Multi-Agent is introduced and the optimized economic operation framework of micro-grid based on Multi-Agent consisting of micro-grid agent, distributed power supply agent, external power distribution network agent, end user Agent and dispatching center Agent is proposed. The economic benefits of the microgrid are analyzed from three aspects: trading of electricity and electricity, peak service, and reduction of line loss. The economic operation model of the microgrid system is also optimized. Select the specific case of micro-grid design to solve the optimal economic performance of the example, and verify the correctness and effectiveness of the optimization of economic operation model based on Multi-Agent micro-grid system.
