The method can diversify the power imbalance to voltage controlled buses in the system via participation factor. Therefore, the automatic generation controls (AGC) of the generators can be incorporated in this power flow model. The DSPF is tested with the IEEE 30 bus system. Numerical results shown that the method can effectively represent the generation control characteristics to the power flow model and potentially be applied to the overcoming competitive electricity supply industry.en-USElectricity Supply IndustryAutomatic Generation ControlArticle
