Electricity market efficiency evaluation method and system based on Bayesian network

The invention discloses an electricity market efficiency evaluation method and system based on a Bayesian network, and the method comprises the steps: obtaining real-time quotation data of a power generator in a market, marginal cost data of the power generator, and market clearing data; constructing an electricity market efficiency evaluation index system, and obtaining an evaluation index system data set by using real-time quotation data and power generator marginal cost data set market clearing data; training the Bayesian network according to the historical data of the power generator to obtain a trained Bayesian network; inputting the evaluation index system data set into the trained Bayesian network model, and performing efficiency evaluation on the electricity market by adopting the Bayesian network; and judging the efficiency condition of the electricity market. The method maintains safe and stable operation of the electricity market. 本发明公开了一种基于贝叶斯网络的电力市场效率的评价方法及系统，包括，获得发电商在市场内的实时报价数据、发电商边际成本数据以及市场出清数据
