【摘要】 传统化石能源日渐枯竭造成全球能源危机凸显,作为新的能量来源和能源清洁替代的有效途径,分布式电源(Distributed Generation,DG)实现持续快速增长,将发挥其独特优势,促进节能减排。然而,多数DG出力与天气环境密切相关,出力无法准确预测控制导致其消纳问题突出,通过挖掘用户侧调荷能力,实施需求响应(Demand Response,DR),统筹调度DG和可控负荷,是DG消纳的有效途径。但这有必要构建一种合理的协同调度模型以降低用户用电成本,促进DG高效利用。OpenADR2.0是一个开放的、互操作性的通信标准,可以支持DG和可控负荷协同调度,具有重要应用前景。论文研究基于OpenADR2.0的DG与可控负荷协同调度问题。主要工作包括:(1)基于统一建模语言对DR业务进行建模,完成静态结构模型和动态行为模型的设计。利用用例图和时序图分别说明DR管理涉及的角色、角色的功能以及各角色信息交互的情况。此外,结合DG和可控负荷协同调度需求扩展公共信息模型,建立了用户能量管理的信息模型。(2)为了解决智能小区中电网与用户不同优化目标的协调问题,提出一种基于OpenADR2.0的智能小区能量协同调度方法。首先,构建了OpenADR2.0应用于智能小区的部署架构,建立了DG和家居设备模型;然后,综合考虑多种DG与居民用户侧响应潜力,提出双层优化调度模型,挖掘用户侧DR潜力,最大化DG就地消纳,实现供需侧双赢。并通过不同模式下优化结果对比,验证了模型的有效性。(3)通过搭建仿真实验平台模拟智能小区与用户的运行环境,OpenADR2.0虚拟顶端节点部署在小区智能控制系统,用户自动需求响应控制系统作为虚拟终端节点,通过智能插座自动控制设备,实现三者之间的交互通信,并阐述了三者信息交互过程,利用仿真实验平台进行了验证。论文研究成果可为可再生能源高效利用,智能小区能量优化调度,自动需求响应的发展以及OpenADR2.0应用部署提供参考。更多还原

【Abstract】 The depletion of fossil fuel causes global energy crisis gradually.As a new energy source and an effective alternative way,DG will achieve sustained and rapid growth and play its unique advantage to promote energy conservation and emission reduction.However,DG output is closely related to weather for causing its consumption.Therefore,it’s necessary to establish a reasonable and effective co-scheduling model by mining customer potential and implementing DR to co-schedule DG and controllable load.OpenADR2.0 is an open,interoperable communication standard that can support co-scheduling DG and controllable load,which has an important application prospect.In this thesis,problems related to DG and controllable load using OpenADR2.0 were studied.Main works are as follows:(1)Firstly,this thesis uses UML to model DR business,including static structure model and dynamic behavior model.Use case diagrams and interaction diagrams are used to illustrate the actors and functions of DR and the information of actors,interaction separately.Then,the models of customer energy management are established on CIM.(2)Secondly,to achieve the coordination optimization of grid and customer in smart community,this thesis proposed an energy co-scheduling approach and a deployment architecture using OpenADR2.0.DG and load model are developed.Then,a bi-level optimal schedule model is proposed based on various DGs and loads potential in DR which can promote DG local consumption and realize a win-win situation of customer and grid.The effectiveness of the model is verified by comparing the results in different modes.(3)Finally,through the establishment of experimental platform to simulate the operation environment of smart community and customer,this thesis achieved the communication of smart community as VTN,customer as VEN and smart outlet to verify the results of its automatic control.The achievements presented in this thesis can be a reference for the development of automatic demand response and OpenADR2.0 in China.更多还原
