摘要
针对分布式发电、大规模可再生能源及电动汽车等新型主动体入网引起电网运行的安全、稳定及经济性问题,将电力系统与生态学、社会学结合,提出电力系统聚合理论的分析方法。重点研究聚合体的特性建模、聚合过程与评价体系、聚合体间的管理框架及相互关系,进而构建主动体聚合化的资源系统、安全防卫系统、再建系统和智能控制系统等四大系统,实现电力系统的聚合化。进一步对基础聚合单元微电网和高级聚合单元多微电网、虚拟电厂(VPP)、超级电网等各种聚合体的结构、物理及社会特性进行研究,探讨聚合体运行过程中的演变规律和互动方式等动态特性。电力系统聚合理论是一崭新的智能电网基础理论,适应大量智能化、多元化、分布式主动体接入智能电网的发展需求。
The penetration of new entities through the grid, such as distributed generations, large-scale renewable sources and electric vehicles, will cause new problems about safety, stability and economy in power systems. Therefore, an aggregation-based view was proposed to analyze the new systems by applying ecological and sociological theory. This issue facing to these new entities focused on the characteristic modeling, evolution behaviors and their evaluation systems as well as management framework. Then, resources, security, rebuilding and intelligent control systems were formed to make these entities aggregate. Furthermore, the physical and social characteristics for basic and advanced aggregation, including multi-microgrids, virtual power plant （VPP） , dynamic characteristics of evolution rules and interaction mechanism for power system, were exploited. The power system aggregation theory was a new basic theory which could meet the needs of a great amount of intelligent, diverse, distributed entities penetrating through the grid.
