Traditional "central" power plants are typically located far from the load centres, and generally use fossil fuel to generate electricity. These systems are inefficient and bring considerable environmental impact. The use of distributed renewable energy sources offers a variety of environmental, social and public benefits that are increasingly in demand as their greenhouse gas emission reduction, economic development, and environmental benefits become more widely known. Within a short time span of four years, from 2004 to 2008, global photovoltaic (PV) and wind power capacity grew 600% and 250%, respectively. In 2008, Canada has reached installed wind energy capacity of 2369 MW, and the average annual market growth for PV technologies has been over 20% for more than a decade. Individual wind and PV systems can be unreliable due to their variable nature. It is generally observed that wind and sun intensity have a complimentary nature; thus when integrated into a single hybrid system, the intermittent but complementary nature of wind and solar provides a more reliable system. Distributed generation (DG) covers different types of generation including but not limited to renewables. The concept of a hybrid green micro-source offers great potential for providing energy to remote rural areas in a vast country such as Canada. A micro-source with 'plug-and-play' flexibility is very useful, since various kinds of energy sources can be added to or removed from the DG system at any time without affecting the performance of other component units. A plug and play micro-source is feasible only if each generating unit component operates as an autonomous entity. Thus, each unit must have an isolated and self-operated control scheme. This research proposal addresses this challenging issue, and aims to answer the following questions: How can a plug and play micro-source of various non-identical units be designed and controlled? What are the associated energy management and system protection considerations? How are costs to be minimized? And, what are the resulting energy savings?

传统的“中央”发电厂通常位于远离负载中心，通常使用化石燃料发电。 这些系统效率低下，带来了相当大的环境影响。使用分布式可再生能源的使用提供了各种环境，社会和公共利益，随着温室气体排放，经济发展和环境利益的需求越来越多。从2004年到2008年的短时间内，全球光伏（PV）和风能能力分别分别增长了600％和250％。 2008年，加拿大的风能能源容量达到2369兆瓦，十多年来，PV Technologies的平均年平均市场增长超过20％。单个风和光伏系统由于其可变性质可能不可靠。 通常观察到风和太阳强度具有免费的性质。因此，当整合到单个混合系统中时，风与太阳能的间歇性但互补的性质提供了更可靠的系统。分布式发电（DG）涵盖了不同类型的一代，包括但不限于可再生能源。混合绿色微型源的概念为向加拿大等广阔国家 /地区的偏远农村地区提供能源提供了巨大的潜力。 具有“插件”灵活性的微源非常有用，因为可以随时将各种能源从DG系统中添加或删除，而不会影响其他组件单元的性能。仅当每个生成单元组件作为自主实体运行时，插头和播放微源才能可行。因此，每个单元必须具有孤立和自我操作的控制方案。该研究建议解决了这个具有挑战性的问题，并旨在回答以下问题：如何设计和控制各种非相同单元的插头和播放微型源？相关的能源管理和系统保护注意事项是什么？如何最小化成本？而且，产生的节能是什么？
