Research progress on power market with large-scale renewable energy:1. Japan's winter electricity market prices in 2021 were analyzed using an optimal dispatch model. Results show that natural gas units have a disproportionate impact on electricity prices at different times within a day. Rising natural gas prices result in high electricity prices during evening peak demand when solar power output is low. Therefore, stable and affordable natural gas supply is crucial for the stable operation of the power system and affordability of electricity prices.2. The Vector Error Correction Model (VECM) was used to analyze the cost pass-through of fuel prices to electricity prices within a day. In a power system with large-scale renewable energy, residual electricity demand fluctuates within a day. The Japanese regional electricity supply market for thermal power generation is a central-peripheral type of market, and the cost pass-through ability of regional market-dominant firms fluctuates within a day due to differences in market power. The empirical results of the VECM indicate that when renewable energy output is high, the cost pass-through ability is weak, whereas when renewable energy output is low, the cost pass-through ability is strong in the Japanese wholesale electricity market.

大规模可再生能源电力市场研究进展： 1．使用最优调度模型对日本 2021 年冬季电力市场价格进行了分析。结果表明，天然气机组在一天内不同时间段对电价的影响不成比例。天然气价格上涨导致晚高峰需求期间太阳能发电量较低时电价上涨。因此，稳定、实惠的天然气供应对于电力系统的稳定运行和电价的承受能力至关重要。 2．矢量误差修正模型（VECM）用于分析一天内燃料价格到电价的成本传导。在大规模可再生能源电力系统中，剩余电力需求在一天之内会发生波动。日本区域火力发电供电市场属于中心-外围型市场，区域市场主导企业的成本转嫁能力因市场力的差异而在一日内波动。 VECM的实证结果表明，当可再生能源发电量较高时，日本批发电力市场的成本转嫁能力较弱，而当可再生能源发电量较低时，成本转嫁能力较强。
