摘要： 为实现“碳达峰、碳中和”目标,发展新能源迫在眉睫.而与传统火电机组不同,新能源机组边际成本为0,随着电力现货市场改革的不断推进,其大规模并网接入势必会对市场交易结果与系统运行情况造成巨大影响.基于实际现货市场运行规则,采用安全约束机组组合与安全约束经济调度模型搭建电力现货市场仿真分析框架,实现电力现货市场的运行模拟.并以某实际省级电网为例,对现货市场环境下新能源对于市场出清结果的影响进行定量分析.仿真结果表明,在现货市场环境下,新能源参与市场会降低全省平均电价与系统运行成本,使得新能源消纳率降低,同时还会压缩市场化机组的利润空间.

Abstract: It is urgent to vigorously develop renewable energy to achieve the goal of “carbon peaking and carbon neutrality”. Unlike traditional thermal units, the marginal cost of renewable energy units is zero. With the reform of the electricity spot market, renewable energy is bound to have a huge impact on the market-clearing results and the operation of the power system. Considering the actual spot market operating rules, an electricity spot market simulation framework is established based on the security-constrained unit commitment and economic dispatch models for the operation simulation of the electricity spot market. Taking the actual data of a provincial power grid as an example, a quantitative analysis of the impact of renewable energy on the market-clearing results in the spot market environment is conducted. The simulation results show that, in the spot market environment, the participation of renewable energy will reduce the average electricity price, the system operating costs, and the renewable energy accommodation. At the same time, the profit space of the market units will be compressed.
Key words: renewable energy generation, electricity spot market, spot market simulation framework, market-clearing price, renewable energy accommodation
