摘要
分布式电源在接入电力系统后会改变潮流网络结构,对电网的网损、电压、无功都产生影响,为此分析两种常见的分布式电源—小水电和风电,提出了潮流计算模型和分布式电源在潮流计算中的处理方法。在潮流计算中,将小水电和风电分别作为PQ节点和PU节点,基于牛顿-拉夫逊法提出考虑无功补偿的含分布式电源的电网潮流计算方法;最后对一个含小水电和风电的广东某地区电网进行潮流计算仿真分析,验证该方法的可行性。
After connecting into power system, distributed power may change load flow network structure and affect trans- mission losses, voltage and reactive power. Therefore, this paper analyzes two kinds of common distributed power including small hydropower and wind power. It proposes load flow calculation model and handling method of distributed power in load flow calculation. In load flow calculation, it takes small hydropower and wind power respectively as PQ node and PU node and proposes power grid load flow calculation method containing distributed power and considering of reactive power com- pensation based on Newton Laphson algorithm. On the basis of simulation analysis on load flow calculation for one regional power grid containing small hydropower and wind power in Guangdong, it verifies feasibility of this method.
