摘　　要：实时电价理论是现代电力市场理论的基础,已应用于单边电力市场。论述了最优潮流不仅提高电网运行的经济性,还提高电网电压的稳定性。发现了隐藏在实时电价中的电压稳定性信息,和用户在实时电价驱动下改变购电节点和数量对电网电压稳定性的影响是积极的。最后用五节点系统算例验证上述观点。The theory of spot price is the foundation of modem electricity market,which has been used in unilateral open electricity market. This paper discusses that optimal power flow not only improves efficiency of power system, but also improves its voltage stability. It discovers voltage stability information hiding in the spot price and that the changing of purchasing point and quantity with the consumers is active to voltage stability under the spot price driving, Finally, five-bus power system is used to compute and testify the above viewpoint.

关 键 词：单边电力市场 最优潮流 实时电价 电力系统 电压稳定
