Distributed Slack Bus Power Flow Part I: Mathematical Model and Framework
(The 30th Electrical Engineering Conference, 2550-10-25) Keerati Chayakulkheeree
This paper presents the mathematical model and test example of distributed slack bus power flow (DSPF) program. 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.
Distributed Slack Bus Power Flow Part II: Prospect and Challenge for Competitive Environments
(The 30th Electrical Engineering Conference, 2550-10-25) Keerati Chayakulkheeree
This paper introduces an application of distributed slack bus power flow to competitive electricity supply industry (ESI). The participation factors of the generators are obtained by the weighted average of AGC accepted quantities in the ancillary services market. The results shows that the proposed method can satisfactory represent the system behavior that all generators are response to power imbalance. In addition, the proposed method results in the better justified AGC setting in competitive electricity market than that of using single slack bus power flow.
