| Description | This work was performed within the framework of the project “eSOLAR: Principle and control of high-efficiency Buck-Boost type Photovoltaic inverter” of the program “Bilateral and Multilateral Research & Technology Cooperation between Greece and China”, funded in Greece by the Operational Program. | en |
| Content Summary | In grid-connected inverter systems, the three-phase asymmetric LCL (A-LCL) filter has outstanding characteristics of simple structure, almost the smallest total inductance, and the strong resistance to the adverse effects of parameter shifts. Nevertheless, the order of this kind of power filter is high, and the control model is complicated due to its asymmetric structure. In this paper, a simplified modeling method, which effectively reduces the system order is proposed, without affecting the control performance. Then, the Kalman filter estimation (KF-estimation) is adopted to reconstruct the PCC voltage. A 380 V/50 Hz/6 kW three-phase laboratory setup has been developed to verify the correctness and effectiveness of the proposed control strategy. | en |
