中文摘要:

      针对电力现货市场可能存在的局部市场力问题，在电力市场仿真平台上验证了在局部断面阻塞情况下，部分机组通过提高报价来行使局部市场力的行为。同时提出了一种通过局部市场力事前评估和事后验证来监测市场主体市场力行使情况的方法，该方法可有效辨识电力现货市场局部市场力行为。最后通过仿真验证了该方法能有效识别市场关键机组，防控其行使市场力，减轻市场运营压力。

英文摘要:

      Aiming at the problem of potential local market power in power market, the behavior of the units which exercise market power in the transmission congestion cases is simulated in the day-ahead power market simulation platform. Based on market power evaluation indices, a comprehensive local market power monitoring method is proposed, which can identify the potential local market power in power market effectively. Finally, numerical simulations illustrate that this method can identify the key units and prevent the potential local market power.
