微电网运行控制解决方案及应用

Solution and application of micro-grid operation control

微电网是分布式电源的有效组织形式。它整合了分布式发电和配电网之间的关系,实现了分布式发电的可控,解决分布式发电接入配电网问题。微电网可视为大电网的可控单元,可并网运行也可以孤立运行。讨论了基于三层结构的微电网控制运行方案中采用的IEC61850标准的微电网通信技术、快速响应的微电网动态稳定控制技术、基于经济优化调度的微电网稳态能量管理控制技术。最后介绍了上述技术在实际微电网工程中的应用情况。

Micro grid is an effective organization form of the distributed resource. Micro grid technology integrates the relationship between distributed resource and distribution network, which realizes the distributed generation controllable, and solves the problem that distributed generations access distribution network. Micro grid can be regarded as a controllable unit of the power grid, which can run under either grid-connectedness or independence. This paper discusses microgrid operation control solution based on three-layer structure, which adopts the microgrid communication technology based on IEC61850 standard, dynamic stability control technology with rapid response, and microgrid energy management steady control technology based On optimizing operation. Finally, a practical engineering of micro grid is introduced.
