中文摘要:

交直流互联电网与调度中心独立计算模式之间存在矛盾,给电网分析和监控带来种种弊端。为克服这一矛盾,在基于异步迭代模式的分布式动态潮流(ADDPF)算法的基础上,提出了以高压直流线路为联络线的交直流互联系统ADDPF算法。该方法针对两端直流系统,直流线路在其两端子系统重复建模,内层交直流潮流计算采用交替求解法,外层将直流线路等值为交流线路构造不动点迭代格式,不断修正外边界节点注入功率实现全网潮流计算。将IEEE标准系统扩展为交直流系统进行测试,可获得与全网一致的动态潮流解。

英文摘要:

The contradiction between AC/DC interconnected power grid and independent calculation mode adopted Dy regtonal control centers, brings in various drawbacks to the analysis and monitoring of a power network. To solve these problems, a distributed power flow algorithm for AC/DC interconnected power grid is proposed. The method is based on asynchronous iteration mode. The algorithm applies to two-terminal HVDC transmission systems taken as tie lines. A DC line is modeled at the two terminal subsystems. Sequential method for AC/DC power flow calculation is used as the interior iteration. During the exterior iterations, a DC line is equivalent to an AC line which is used to construct a fixopoint iteration about boundary state variable, the equivalent iniection power on the boundary buses is modified gradually to obtain a power flow result for the whole system. The experimental results of IEEE standard systems extended to AC/DC power systems indicate that the algorithm is accurate.
