摘要
我国新能源快速发展,新能源大发时消纳难和新能源少发时电力保障供应难的矛盾突出,对新型电力系统灵活性提出更高要求。在传统的以水火电为主的优化调度模型基础上,基于我国能源结构与灵活性资源特性,构建了计及灵活性改造后煤电机组调节特性、特高压直流输电能力与煤电开机方式耦合关系、电制氢新型资源调节特性的多元灵活资源多目标优化调度模型。以某省级电网实际数据验证了模型的有效性与可行性,验证结果表明,建立的模型有利于发掘利用源网荷储输等各类资源调节能力,提升系统整体灵活调节能力,支撑新能源消纳和电力保障供应,助力我国新型电力系统的构建。
The rapid development of new energy in our country highlights the contradiction between the difficulty in consuming and ensuring the supply of electricity when new energy is abundant and when new energy is scarce,which puts higher demands on the flexibility of the new power system.Based on the traditional optimization scheduling model mainly based on hydrothermal power,and based on the energy structure and flexible resource characteristics of China,this paper constructs a multi-objective optimization scheduling model that takes into account the regulation characteristics of coal-fired units after flexibility transformation,the coupling relationship between ultra-high voltage direct current transmission capacity and coal-fired units start-up mode,and the regulation characteristics of new types of resources for hydrogen production.The effectiveness and feasibility of the model were verified using actual data from a provincial power grid.The verification results showed that the established model is conducive to exploring and utilizing various resource regulation capabilities such as source network load storage and transmission and improving the overall flexible regulation ability of the system.
