摘要
分布式光伏电源由于其出力具有不确定性从而影响配电网潮流分布及走向。从分布式光伏电源接入位置、接入容量、配变负载率等因素出发分析了分布式光伏电源的接入影响配电网电压的机理,考虑负荷分布的不确定性,以线路电压不越限为约束条件,建立了分布式光伏电源最大准入功率的计算模型。并通过所举算例验证了该模型的合理性。并提出了提高分布式光伏电源最大准入功率的措施。
The power distribution and trend of the distribution grid is affected due to the uncertainty of output of the distributed photovoltaic power supply.The mechanism of influence of the voltage of distribution grid by the connection of distributed photovoltaic power supply is analyzed from such aspects as connection position,capacity,distribution load ratio of the distributed photovoltaic power supply.The load distribution uncertainty is considered.The calculation model of maximum access power of the distributed photovoltaic power supply is set up with the line voltage within a limit as the constrain condition.The reasonableness of the model is verified by the calculation example and the measures on improving maximum access power of the distributed photovoltaic power supply is proposed.
