要約(英語): This paper proposes an estimation method of actual load and PV output values in distribution systems using a power flow measuring instrument and smart meters. For distribution system operations, the requirement for estimating actual load and PV output values separately has been expanding as introduction of PV systems increases. Therefore, in order to estimate them with high accuracy, the proposed method utilizes measurements from a power flow measuring instrument and smart meters. The method consists of a two-stage process with different calculation periods. The long-period estimation stage is performed at a measurement period of the smart meters and the short-period estimation stage is performed at a measurement period of the power flow to update the long-period estimation result. The method is applicable to a wide range of distribution systems and requires less additional costs. Through evaluation of simulation results, it is confirmed that the proposed method is performed with higher accuracy than conventional methods.
