【摘要】 我国电力系统将在全国范围内实现大并网，为了保证市场化运作的电力系统的安全稳定，各调度中心之间必须通过某种形式的相互沟通和协调，以准确地掌握整个电力系统的实时状态。互联电网的这种广域分布的特点也决定了分布式系统是监控系统发展的必然趋势。网格技术作为一种分布式计算技术，整合了广域分散分布的资源，具有满足互联电网监控系统性能的潜力。但是随着网格技术的发展，网格模型的五层沙漏结构在面对大规模分布式资源时所形成的资源整合的瓶颈问题也凸现出来。P2P技术也是一种分布式技术。它和网格技术从构建到应用的整个流程中都具有互补性。如果对它们的实现方式取长补短，构建具有P2P模式的网格体系，就能够有效的解决网格的瓶颈问题。这样构建的网格体系可以提供更高性能、更加健壮的网格环境。本次研究的主要工作是：综合各种电力网格和P2P模型，提出了电力系统的P2P-Grid模型，以解决电力网格应用于电力系统的大规模资源整合所面临的瓶颈，并通过P2P的技术优势，提高电力网格其他方面的性能。一个完整的区域互联电力系统网络的各部分分别属于不同的电力市场运营模式下的公司，成员公司间如何协同完成电网的分析和计算，将是电力网格必须解决的一个问题。本次研究利用JXTA技术搭建基于P2P技术的电力计算网格原型系统，为了模拟区域电网的不同部分，对多个IEEE电力模型进行不同方式的分块，并在该原型系统上实现了各区域间的一体化分布式潮流计算。实验结果证明了P2P技术和电力网格技术融合的可行性和有效性。研究工作还初步探讨了该模型的开放性能。更多还原

【Abstract】 The countrywide power network will be achieved to grid-connected. In order to ensure the safety, stabilization and the real-time state precisely, in which each dispatched centre must communicate and cooperate by some way of the power grid. Such extensive distributed characteristic of interconnected electric network determinates the inevitable trend of distributed system in the development of monitoring system. Grid has the potential to satisfy the demand of monitoring system of interconnected electric network in future, because it integrates the extensive distributed source. However, with the development of grid, the grid model structured via five layers of sandglass has been become a bottleneck in resource integration.P2P(peer-to-peer) is a distributed technology. Both P2P and Grid are complementary from their construction to application. If the advantages of P2P is employed to offset grid’s weakness, the bottleneck problem can be resolved effectively by constructing the grid system with P2P mode. Such a system can provide more advance and stronger environment of grid.In this study, all kinds of P2P and grid model are synthesized. A novel architecture, i.e. P2P-Grid model of the power system, is introduced to deal with the bottleneck which exists in resource integration of large-scale power grid, and other performances of grid will be enhanced via P2P technique. Every part of the whole regional interconnected power system belongs to different company with different power marketing mode. So it will be a hot potato for power grid to mutually accomplish the analysis and computation of power network.In this work, a prototype system of power computation grid based on P2P is constructed by JXTA. In order to simulate different parts of the regional interconnected power system, some plats based on a lot of IEEE model are incised, and the corresponding integrative distributed power flow are computed. The simulation result has demonstrated the effectiveness and feasibility of the proposed approach. The compatibility and Transplantation of this model is attempted to discuss.更多还原
