微電網建設中的模型與應用（二）

摘要：分散而斷續的發電是電力產業變化的一個重要發展方向，隨著新能源的發展使電網變得更加復雜，微電網便是其中之一。微電網是由風、光等發電裝置，加上開關電源變流器、由PC等控制器進行管理，與市電網并聯后形成雙電源、雙向能流，并能完善運行、保護的小型電力系統。本文系統闡述了微電網的發展、含義、特征、運行和控制,重點對微電網變流器工作原理進行論述。 敘詞：微電網/模型/XX電力電源/開關電源變流器/實驗平臺指標 Abstract：Disperse and intermittent power generation is an important direction of the development of power industry. As the rise of new energy makes grid more complex, microgrid turns up. It is a small, perfect-operating-and-protecting power system managed by controllers like PC and paralleled with city grid to form double power and dual energy flow, which combines wind and PV generating apparatus with switching power converter. This paper systematically introduces its development, definition, features, operation and control, focusing on the analysis of the operating principle of microgrid converter.
