The goal of China’s new round of electricity market reform is to orderly release the plan of power generation and power utilization and gradually expand the scale of market-oriented transactions. The generation adequacy is an indicator that needs to be paid attention to during releasing the plan of power generation and power utilization. Insufficient generation adequacy will result in market monopoly and high market-clearing prices. Given this background, the market power and bidding strategies of generators under the low and high generation adequacy are analyzed in this paper. Then, a synthetic decision model for the energy allocation between bilateral contracts and a pool market and the bidding strategy in the pool market is constructed considering the generation adequacy. Case studies are performed for demonstrating the decision-making model and simulation results show that the proposed model can assist generators to make energy allocation and bidding decision based on the generation adequacy, own power generation capacity and bilateral contract prices, and can provide guidance for market operation agencies to gradually release the plan of power generation and power utilization.

我国新一轮电力市场改革的目标是有序发布发电用电规划，逐步扩大市场化交易规模。发电充足率是在发布发电用电规划时需要关注的一个指标。发电不足将导致市场垄断和高市场出清价格。在此背景下，本文分析了低发电充足率和高发电充足率下发电机组的市场力量和竞价策略。在此基础上，构建了考虑发电充足性的双边合同与电力池市场的能源配置综合决策模型和电力池市场的竞价策略。
