摘要
网络重构在供电恢复、提升新能源渗透率和运行降损等方面有较广泛的应用。为提升地区电网长期运行的经济性,计算了地区电网在两种不同运行方式下的日有功损耗。在不同负荷情况下,计算了地区电网不同运行方式下的有功损耗,为地区电网长期运行方式的固化提供了基础。最后,计算了地区电网在运行方式固化后,即网络重构后运行的月降损电量,证实了在不影响电网运行安全性和供电可靠性的前提下,通过网络重构即可实现地区电网长期经济运行。
Network reconfiguration is widely applied in power gird for service restoration,renewables penetration promotion and power loss reduction.In order to realize the economic operation of region power grid,the daily active power losses of region power grid under two different operation modes are calculated.Under different loading conditions,the active power losses of region power grid under different operation modes are calculated,which provides a foundation for the consolidation of regional power grid in long-term operation.Finally,the monthly loss reduction of regional power grid is calculated after the operation mode is solidified,that is,after the network reconfiguration.It is verified that under the demands of safety operation and reliability of power supply,the long-term economic operation of regional power grid can be realized through network reconfiguration.
