It is of prime importance to realize the integration of variable renewable energy sources (VRE) for sustainable energy society. The frequency regulation becomes an important issue in the power system with more VRE integration due to uncertain output fluctuation of VRE generators. Another issue caused by VRE integration is congestion management in transmission network, and locational marginal price (LMP) has been applied in some power networks to avoid the congestion issue based on economic mechanism. The congestion issue has to be considered in the balancing control to cope with frequency fluctuation because more balancing power could be needed due to the VRE integration. Hence, in this paper, the application of LMP to the balancing power market in terms of capacity procurement was proposed. A part of transmission capacity was assigned to the balancing control and the location of the control reserves was given with LMP. The effectiveness of the proposed method was verified through numerical simulations based on a combined model for both the frequency regulation and the power flow calculation. It was shown that the congestion issue was properly mitigated with keeping the frequency fluctuation by using the proposed method. © 2022 Institute of Electrical Engineers of Japan.

平衡电力市场中基于区域边际价格的电力系统拥塞管理

实现可变可再生能源（VRE）的整合对于可持续能源社会至关重要。由于VRE发电机的输出波动不确定，调频成为VRE集成较多的电力系统中的一个重要问题。VRE 集成带来的另一个问题是输电网络中的拥塞管理，一些电力网络已经应用位置边际价格（LMP）来避免基于经济机制的拥塞问题。在平衡控制中必须考虑拥塞问题以应对频率波动，因为由于 VRE 集成可能需要更多的平衡功率。因此，在本文中，提出了在容量采购方面将 LMP 应用于平衡电力市场。部分传输容量分配给平衡控制，控制储备的位置由 LMP 给出。基于频率调节和潮流计算的组合模型的数值模拟验证了所提方法的有效性。结果表明，通过使用所提出的方法，在保持频率波动的情况下，拥塞问题得到了适当的缓解。© 2022 日本电气工程师学会。由 Wiley Periodicals LLC 出版。结果表明，通过使用所提出的方法，在保持频率波动的情况下，拥塞问题得到了适当的缓解。© 2022 日本电气工程师学会。由 Wiley Periodicals LLC 出版。结果表明，通过使用所提出的方法，在保持频率波动的情况下，拥塞问题得到了适当的缓解。© 2022 日本电气工程师学会。由 Wiley Periodicals LLC 出版。
