Passivity-Short-based Stability Analysis on Electricity Market Trading with Communication Delay

摘要

In this paper, we analyze the stability of the electricity market trading system with communication delays based on Passivity-Short and show the electricity market trading system has the characteristics of plug and play operation. And then, we propose the dynamic pricing method considering negative price when supply surplus occurs. Regarding this system, especially, even when there is a power flow among each area and communication delays among market participants, we show that the stability of market trading system is guaranteed. Finally, the effectiveness of the proposed method is confirmed by numerical simulations.
