H²予見出力フィードバックの導出とその負荷周波数制御への応用

抄録

This paper presents a continuous-time H² preview control based on partial information, and its application to load frequency control (LFC). It is expected that preview supply and demand information improves load frequency control performances. In common power system, however, we have difficulties in measuring all the internal states which compose the overall generator. To solve this difficulty, a design method of H² preview control system is proposed in an output feedback setting. The design method enables to treat the preview uncertainties by introducing an independent disturbance channel into the corresponding generalized plant. It is shown that the frequency variation in the power system is effectively attenuated by reflecting the bandwidth of load variation.
