<p>[Problem] To provide a grid connection apparatus, wherein distortion of the waveform of a current outputted by an inverter circuit is inhibited. [Solution] At least two errors among a plurality of errors (edi, eqi) calculated in the past are added up with weighting applied to each error. The newest errors (ed0, eq0) among the errors (edi, eqi) to be added up are subjected to greater weighting than the other errors, so that distortion in alternate current to be outputted by the inverter circuit will become smaller. Control values (Cd, Cq) are corrected with added values (ad, aq) obtained by this adding.</p> |
