摘要: 自“2030年前碳达峰、2060年前碳中和”的目标提出后,中央财经委员会第九次会议又进一步提出实现该目标的基本思路和主要举措,特别是实施可再生能源替代行动,深化电力体制改革,构建以新能源为主体的新型电力系统。这些举措必将导致电源结构的重大调整。另一方面,近年来世界范围内电力市场中各类负面事件接连不断,引起各方广泛关注。这些事件产生的原因与电源结构缺陷和电力市场设计不合理有很大的关系。结合近期全球电力市场典型事故的介绍和原因分析,重点探讨了电源结构的变化所引起的安全风险和电能价值的多样化等问题,分析了电力市场体制机制所面临的挑战,并提出了初步解决方案。电力定价和电力市场设计应建立在电能价值规律的基础之上。在可再生能源大规模接入的背景下,电能除了传统电力市场中的容量价值、电量价值,还具有灵活性、安全性和弹性价值等多种不同的价值,使得问题更加复杂,因此针对这些问题进行了初步分析。

Abstract: Since the goal of "having CO2 emissions peak before 2030 and achieving carbon neutrality before 2060" was put forward, the ninth meeting of the Central Finance and Economics Committee has further proposed the basic ideas and main measures to achieve this goal, especially implementing renewable energy substitution actions, deepening the reform of the power system and building new power systems with new energy as the main power source. These measures will inevitably lead to major adjustments in the generation mix. On the other hand, various negative events in the electricity markets around the world occurred one after another in recent years, which has attracted widespread attention from all the world. The reasons for these events are highly related to the defects of generation mix and electricity market design. On basis of the introduction and cause analysis of typical accidents in the global electricity markets in recent years, this paper focused on the safety risks and diversification of electricity value caused by the changes in generation mix, analyzed the challenges faced by the electricity market designs, and proposed preliminary solutions. Electricity pricing and electricity market design should be based on the law of electricity value. In the context of large-scale integration of renewable energy, electricity not only has capacity value and energy value in traditional electricity markets, but also has various other values such as flexibility, security and resilience, which makes the problem more complicated. This paper carried out a preliminary analysis of these issues.

Key words: electricity market, law of value, generation mix, flexibility
