要約(英語): The grid connection inverter is built in the PCS (Power Conditioning Subsystem) for the distributed power supply, such as photo voltaic system. Recently, there has been considerable advances in the research on power flow using PCS. In order to adjust the power in the PCS, it is necessary that the grid connection inverter of the PCS predicts the load and output fluctuation in the customer side. Therefore, this paper investigates a load estimation in the grid connection inverter of the PCS. The proposed estimation method adds a superimposing pseudo-white signal to the inverter reference. The validity of the proposed estimation method is verified experimentally. In addition, the pseudo random binary sequence creates a pseudo-white signal for load estimation. As a result, it is experimentally clarified that the proposed method reduces the estimation time and improves the estimation accuracy.
