摘要:

作为最成熟的储能形式,抽水蓄能是未来综合智慧能源系统支撑“碳达峰、碳中和”目标实现的重要组成部分,但缺乏合理的电价制定策略是制约其发展的重要因素。针对该问题,研究了综合智慧能源系统中,可再生能源与抽水蓄能联合运行场景下,抽水蓄能的两部制电价机制。根据经营期定价法确定抽水蓄能容量电价,考虑“抽水蓄能+可再生能源”的经济性优势,建立抽水蓄能与风电联合优化调度模型,以引入抽水蓄能后的系统总成本减少量和抽水成本为目标函数,得到抽水蓄能的合理抽发策略,再以价格需求关系和补偿变动成本为原则分别制定抽水蓄能电站抽水时段和发电时段的电量电价。最后通过算例仿真分析了抽水蓄能电站对实现系统低碳运行的作用以及电站抽水成本对电价的影响,验证了抽水蓄能两部制电价制定策略的有效性。

Abstract:

As the most mature form of energy storage, pumped storage will be an important supportive technique for integrated intelligent energy systems to achieve carbon peaking and carbon neutrality. But the development of the technique is hampered by the lack of a proper pricing strategy. In response to this problem, the two-part tariff strategy for pumped storage power plants which operate in corporation with an integrated intelligent energy system is proposed. According to the operation pricing strategy, the tariff is determined by the capacity of a pumped storage power plant. In view of the economic advantages of "pumped storage + renewable energy", an optimal dispatch model for the combination of pumped storage and wind power is established. Taking the reduction of total cost and pumped storage cost of the combined system as the objective functions, a rational pumping strategy for the installed pumped storage power plant is carried out. And the tariffs in water pumping stage and in power generation stage of the power plant are figured out according to the relationship of demand and price and variable cost compensation principle, respectively. The effect of integrating a pumped storage power plant in an integrated intelligent system on the low-carbon operation and electric price of the combined system is verified by a case, which proves the effectiveness of the two-part tariff strategy of pumped storage power plants.

Key words: carbon neutrality, pumped storage power plant, integrated intelligent energy, renewable energy, two-part tariffs, wind power consumption, low -carbon operation
