【目的】为适应新能源汽车的快速增长和广泛应用,我国鼓励建设和发展一体化综合交通能源服务站,对此提出一种计及动态定价策略的电-氢综合能源站经济运行方法。【方法】首先,通过解析新能源汽车用户到达电-氢综合能源站的时序特征与充能行为特性,利用蒙特卡洛方法构建新能源汽车充能需求预测模型。其次,基于新能源汽车充能所需电量负荷比和新能源消纳率、综合能源站的储能容量动态变化特征和外部购能成本等因素,制定了包含动态售电价格和动态售氢价格的电-氢综合能源站动态定价策略,引导新能源汽车用户参与需求响应,同时针对氢能公交车和氢能环卫车进行负荷管理,提出电-氢综合能源站经济运行方法。【结果】算例仿真结果表明,相比固定定价策略,动态定价策略可显著提高电-氢综合能源站的收益,其售电、售氢收入和售能总收益分别提高了24.13%、4.57%和14.59%;引入负荷管理后,电-氢综合能源站的运行总成本下降10.3%,售能收益进一步提升。【结论】文章所提方法可突破固定定价策略的局限性,实现电-氢综合能源站经济运行。
[Objective] China encourages the construction and development of integrated comprehensive transportation and energy service stations to accommodate the rapid growth and widespread adoption of new-energy vehicles. This study proposes an economic operation method for electric-hydrogen integrated energy stations that incorporates dynamic pricing strategies. [Methods] First, the study analyzes when new-energy vehicle users arrive at energy stations and how they charge their vehicles. Based on this, a charging demand prediction model is developed using the Monte Carlo method. Second, the study considers several factors. These include the power load ratio for charging, the absorption rate of new energy, changes in station storage capacity, and external purchasing costs. Based on these, a dynamic pricing strategy is formulated. The strategy includes both electricity and hydrogen pricing. This strategy encourages new-energy vehicle users to participate in demand response programs. It also helps manage the energy loads of hydrogen buses and sanitation vehicles. Based on this, an economic operation method for electric-hydrogen integrated energy stations is proposed. [Results] Simulation results show that dynamic pricing strategies significantly improve station revenue compared to fixed pricing strategies. Specifically, electricity sales, hydrogen sales, and total energy sales revenue increased by 24.13%, 4.57%, and 14.59%, respectively. Meanwhile, the total operating cost decreased by 10.3%, further boosting net revenue. [Conclusions] The proposed method overcomes the limitations of fixed pricing strategies and enables more economical operation of electric-hydrogen integrated energy stations.

UK plans to ban the sale of new diesel and petrol cars by 2030 to be replaced by electric vehicles (EVs). The question is, will the UK's electrical grid infrastructure ready for this change? This comparative study investigates the effect of UK green vehicles on the electrical grid and presents a new insight into improving their energy demand and carbon dioxide (CO) emissions to the electrical grid. The results show that even when there is a very high level of market penetration of EVs, the overall effect on annual energy consumption may seem minimal. On the contrary, the effect that EVs may have on the electrical grid is dependent on the time-of-day EVs are being charged. Therefore, this study concludes that measures need to be put in place to control charging times of EVs and this would help restrict the total daily electricity and electrical energy demands. The introduction of EVs reduces the overall CO emissions mainly because a proportion of petrol and diesel cars are replaced by EVs. However, CO emissions can only reduce up to a certain level and this reduction of CO will have less effect due to an increasing number of EVs in the electrical grid. To reduce CO emissions further, the electricity that relies on high-carbon fossil fuels in the electrical grid should be set at the minimum level.© 2022. The Author(s).
