摘　　要：分布式光伏输出功率与用户实际负荷功率的耦合增加了净负荷的波动性和不确定性。为此提出了一种对用户实际负荷和光伏出力进行数据解耦方法来估计基线负荷。首先根据用户特点分为对照组和需求响应组,估算用户的实际负荷;然后利用估算得到的用户实际负荷,得到用户每日的光伏出力估算值;接着将估算得到的用户实际负荷与光伏输出功率在需求响应时段内进行叠加,得到用户的基线负荷估计值;最后给出了对于基线负荷估计结果的评价指标。为了验证方法的有效性和可行性,采用真实的数据集对分布式系统的识别和基线负荷估计进行了仿真研究。结果表明,提出的光伏-负荷解耦法有着更好的基线负荷估计准确性。The coupling of distributed photovoltaic output power and user’s actual load power increases the volatility and uncertainty of the net load.For this reason,a data decoupling method for user actual load and photovoltaic output was proposed to estimate the baseline load.The whole idea of this method is as follows:first,divide the users into a control group and a demand response group according to user characteristics to estimate the user’s actual load;then utilize the estimated user’s actual load to get the user’s daily photovoltaic output estimate;after that superimpose the estimated user’s actual load on the photovoltaic output power during the demand response period so as to obtain the user’s baseline load estimation value;finally,the evaluation index for the baseline load estimation result was given.In order to verify the effectiveness and feasibility of the method,a simulation study was carried out on the identification and baseline load estimation of the distributed system by use of real data sets.The results show that the proposed photovoltaic-load decoupling method has better accuracy of baseline load estimation.
