Research on the Architecture of Distributed Generation Cyber-Physical System

随着新能源分布式发电在电力系统中的比例日益增加,快速响应发电出力的变化、维持电能供用平衡、优化微电网运行效率的需求,增加了电网调度的复杂性,要求电力系统的管理更智能、更高效。文章引入信息物理融合系统的理念,提出了一个包含双向通信网络、电网态势感知、多源大数据处理和多源协同优化控制的分布式发电信息物理融合系统(Distributed Generation Cyber-Physical System,DGCPS)架构方案,并详细分析了DGCPS架构中涉及的关键技术,试图解决传统的电网集中控制系统与大量的分布式能源动态接入管理在架构上无法匹配的问题。

With the increasing proportion of new energy distributed generation in power grid,the demand of rapid response to generation changing,maintaining the balance of power supply and consumption,and optimizing the operation efficiency of micro-grid increases the complexity of power grid dispatching requires the management of power system to be more intelligent and efficient.This paper introduces the concept of cyber physics fusion system,and then proposes a distributed generation cyber-physical system(DGCPS)architecture which includes bidirectional communication network,power grid situational awareness,multi-source big data processing and multi-source collaborative optimization control.Finally,the key technologies of DGCPS architecture are analyzed in detail.This paper attempts to solve the problem that the traditional centralized control system of power grid cannot match the architecture of a large number of distributed energy dynamic access management.
