微电网系统组成分析与研究

微电网结构比较复杂,需要较多的功能单元来实现电能的灵活调配。目前针对微电网方面尚无详细的国家标准,而且受建设条件的制约,每个微电网工程的型式、结构以及可实现的功能各不相同,难以体现微电网的完备性。依托国内首个由政府主导的较大规模的新能源应用及智能微电网示范项目,从发电、储电、配电、用电4个环节论述了一个较完备的微电网所应具备的功能子系统,并对该微电网工程进行了案例分析,分析结果可为微电网工程建设提供技术方面的支撑。

Analysis of micro electric-grid system composition

Micro electric-grid has complicated structure and needs many functional units for flexible dispatch of power. Due to the lack of detailed national standards on micro electric-grid, so the construction condition limitation, the type, structure, function of each micro electric-grid project are different, it is difficult to embody the completeness of micro electric -grid. Based on a first large-scale demonstration project of new energy application and smart micro electric-grid led by government, the necessary function subsystem for a complete micro electric-grid is discussed from 4 links of power generation, storage, dis-tribution and consumption. A case of micro electric-grid is analyzed to provide technical support for micro electric-grid con-struction.
