| 摘要: |
| 从分布式电源选址定容算法分析入手，对分布式电源选址定容在配电网和微网中应用的差异化方案进行了综述。首先，对分布式电源并网接入的载体——配电网和微网(Micro-Grid, MG)，从拓扑结构、对外接口等物理特性和故障前、后运行方式等运行特性进行了分析比较，两种载体存在一定的相似性。然后，从优化目标、优化算法方面分析比较了分布式电源在配电网和微网选址定容的相互借鉴性和差异性，指出:在考虑不同设备接入、不同约束条件的基础上，分布式电源选址定容优化目标通常为经济性和/或可靠性，而在结合具体应用场合时会体现出不同方案的差异性；进而从优化目标的侧重点设定、运行方式的差异、储能接入的位置与容量等方面对分布式电源选址定容问题在配电网与微网中的异同点进行了具体的比较。最后指出在考虑前述异同点以外，还应该对优化目标最终达成度、接入设备的精细化建模程度、网络自身调整能力三个方面进行考虑，使最终选址定容方案能够服务于未来实际工程的需要。 |

| Abstract: |
| This paper reviews DGs’ locating and sizing methods applied in micro-grids and in distribution network, and compares them in the above two applications. Firstly, comparison of physical characteristics including topology and outside port to grid, and operation modes including all kinds of modes before and after faults, is carried out between the micro-grids and distribution network. According to the fore-mentioned comparison, the similarities are found, and then the analysis and comparison of DGs’ sizing and locating problems are implemented deeply as follows. Following problems are pointed out:firstly, the economic or/and reliability objectives are commonly selected, while the difference of the practical applications in specific situations will result in the final different schemes. Secondly, the comparison in the direct and indirect connections of DGs is carried out deeply according to the optimal objectives, operation modes, the access of distributed storage units, et al. Finally, besides the above difference points, three aspects concerning the reachable degree of the assigned objective, the meticulous modeling on certain equipments connected into grid, the regulative capability of grid consisting of some topology adjusting equipments and power quality improvement equipments, are discussed further to help the practical engineering.
