摘要
新型电力系统建设是我国电力行业的重大转型,其需求来源于经济社会发展,其实现依赖于电力系统运行机理的改进。从近10年电力系统的发展历程和阶段性目标分析出发,基于“双碳”目标,对新型电力系统的电源构成、特点及运行模式进行逆向推理和分析,进而分析新运行模式下的部分关键技术需求。指出:为了实现“双碳”目标,电力系统电源构成必须进行巨大调整,特别是在2030年之后;在新型电力系统中,发电侧将以新能源为主体,用户侧将出现大量产销者并呈现大量分布自治的形态,能源互联网将成为新型电力系统的基础支撑,电网调度将主要基于市场化机制实现;新型电力系统的建设在电力电量平衡、系统安全、有源配用电网管控、新能源发电和并网、电力交易和调度等方面迫切需要相关创新技术的支撑。
The construction of new style power system is a major transformation of China’s power industry,its demands come from economic and social development,and its realization depends on the improvement of operation mechanism of power system.Starting from the analysis of development process and phased goals of power system in recent 10 years,the power source composition,characteristics,and operation mode of new style power system are inversely deduced and analyzed based on the“double carbon”goal,and some key technical requirements under the new operation mode are further analyzed.It is pointed out that the power source composition of power system must be greatly adjusted in order to achieve the“double carbon”goal,especially after 2030.In the new style power system,renewable energy will become the main body on the generation side,there will be a large number of prosumers on the user side which show a large number of distribution and autonomy forms,energy internet will become the basic support of new style power system,and the power grid dispatching will be mainly realized based on the market-oriented mechanism.The construction of new style power system urgently needs the support of relevant innovative technologies in terms of power and electricity balance,system security,management and control of active distribution and utilization grid,power generation and grid-connection of renewable energy,power trading and dispatching,etc.
