联合国宣布2012年为"人人享有可持续能源国际年"。世界人口中有很大一部分（约13亿人）目前生活在没有电力的情况下，为他们提供电力的发展努力进展相对缓慢。本论文遵循的技术，可以使社区拥有和经营的微电网出现完全基于当地的供应和需求，该社区的发展。虽然本论文以DC/DC转换器的技术分析结束，但为了正确理解它将被使用的上下文，需要涵盖大量的背景知识。在介绍了典型的农村电气化的努力，并指出了这些项目的一些缺点，本文介绍了一些前沿的努力，结合联合收割机太阳能家庭系统技术与蜂窝技术，并讨论了这种婚姻的技术的好处。接下来，该研究对这项新技术提出了一些调整，并提供了一个基于这些修改的社区中太阳能家庭系统传播的高水平经济演示。然后，它进一步扩展了这一概念，并提出增加一个DC/DC转换器，可以将这些单独的太阳能家庭系统变成一个适当的微电网。本文详细阐述了在PSCAD中模拟这种微电网的开发过程，包括太阳能家庭系统的各个组件和设计转换器的具体任务，该转换器将形成拟议的微电网的骨干。最后的模拟和分析表明，微电网在技术和经济上都是可行的发展中国家的应用。
The United Nations has declared 2012 the “International Year of Sustainable Energy for All”. A substantial portion of the world’s population (some 1.3 billion people) currently live without electricity and development efforts to reach them are progressing relatively slowly. This thesis follows the development of a technology which can enable community owned and operated microgrids to emerge based solely on the local supply and demand of that community. Although this thesis ends with the technical analysis of a DC/DC converter, there is a significant amount of background to cover in order to properly understand the context in which it will be used. After providing an introduction into typical rural electrification efforts and pointing out some of the shortcomings of these projects, this thesis introduces some cutting edge efforts which combine solar home system technology with cellular technology and discusses the benefits of such a marriage of technology. Next, the research proposes some tweaks to this novel technology and provides a highlevel economic demonstration of the spread of solar home systems in a community based on these modifications. It then takes this concept even further and proposes the addition of a DC/DC converter which could turn these individual solar home systems into a proper microgrid. This thesis elaborates on the development process of simulating such a microgrid in PSCAD, including the individual components of a solar home system and the specific task of designing the converter which would form the backbone of the proposed microgrid. The final simulations and analyses demonstrate a microgrid that is both technically and economically feasible for developing world applications.
