Description
技术领域Technical Field
本发明属于电力系统及其自动化领域，特别涉及一种电网仿真分析算例及其生成方法、生成系统、设备、介质。The present invention belongs to the field of electric power systems and automation thereof, and in particular relates to a power grid simulation analysis example and a generation method, generation system, equipment and medium thereof.
背景技术Background Art
标准算例是开展电力系统特性分析的基础，已被广泛应用于电力系统稳态、暂态分析，控制措施设计、分析和验证等领域。标准算例通常源自实际电力系统的抽象和简化，能反映实际系统存在的各类稳定特征。针对传统电力系统，国际上已经形成丰富的标准算例集，包括装备级和系统级算例。Standard examples are the basis for power system characteristic analysis and have been widely used in the fields of steady-state and transient analysis of power systems, design, analysis and verification of control measures. Standard examples are usually derived from the abstraction and simplification of actual power systems and can reflect various stability characteristics of actual systems. For traditional power systems, a rich set of standard examples has been formed internationally, including equipment-level and system-level examples.
IEEE标准算例是各类电力系统研究中最为常用的电力系统标准算例。IEEE标准算例集中包含3节点、5节点、9节点、11节点、13节点、14节点、30节点、39节点、43节点、57节点、118节点、145节点、162节点、300节点等各种不同节点数的电网网架模型、模型参数和基态潮流断面。IEEE standard examples are the most commonly used standard examples in various power system studies. The IEEE standard examples include grid models, model parameters and base state flow sections with different numbers of nodes, such as 3 nodes, 5 nodes, 9 nodes, 11 nodes, 13 nodes, 14 nodes, 30 nodes, 39 nodes, 43 nodes, 57 nodes, 118 nodes, 145 nodes, 162 nodes, and 300 nodes.
构建以新能源为主体的新型电力系统，系统结构形态和运行方式将发生重大变化，在电力平衡、安全运行、运行控制等方面面临严峻挑战。目前电力系统标准算例中缺乏标准的体现新型电力系统特征的电网模型。The construction of a new power system with new energy as the main body will bring about major changes in the system structure and operation mode, and face severe challenges in power balance, safe operation, operation control, etc. At present, there is a lack of standard power grid models that reflect the characteristics of the new power system in the standard calculation examples of power systems.
现有研究采用的电网模型大都基于IEEE标准算例模型或国内实际电网模型。其中，IEEE标准算例模型的电网网架和系统参数是从上个世纪的北美电网抽象设计而来，线路传输能力与当前电网现状存在很大差异，且未能提供机组电源类型；国内实际电网模型的新能源装机比例不足，尚未达到新型电力系统新能源为主体的目标，且实际电网在不断建设中，其电网模型并不固定。为研究面向新型电力系统的电网调控技术，不同的研究对IEEE标准算例模型或实际电网模型进行不同的改造，研究成果无法横向对比。Most of the power grid models used in existing research are based on IEEE standard example models or domestic actual power grid models. Among them, the power grid structure and system parameters of the IEEE standard example model are abstractly designed from the North American power grid in the last century. The line transmission capacity is very different from the current status of the power grid, and the unit power supply type is not provided; the proportion of new energy installed capacity in the domestic actual power grid model is insufficient, and the goal of new energy as the main body of the new power system has not yet been achieved. In addition, the actual power grid is constantly under construction, and its power grid model is not fixed. In order to study the power grid control technology for the new power system, different studies have made different modifications to the IEEE standard example model or the actual power grid model, and the research results cannot be compared horizontally.
综上，新型电力系统以大量不确定随机波动电源为主体，系统面临电力平衡保障难度加大的挑战，采用通过常规机组裕度调节的传统调控技术面临巨大挑战，研究模型驱动的多资源、多目标的协调控制方法迫在眉睫；由于现有标准算例和目前实际电网模型均不满足新能源为主体的特征，因此需要新能源装机占比可配置的电网仿真分析算例生成技术，以满足模型驱动的新调控技术研究需求。In summary, the new power system is dominated by a large number of uncertain randomly fluctuating power sources. The system faces the challenge of increasing difficulty in ensuring power balance. The traditional control technology that uses margin adjustment of conventional units faces huge challenges. It is urgent to study model-driven multi-resource and multi-objective coordinated control methods. Since the existing standard examples and the current actual power grid models do not meet the characteristics of new energy as the main body, there is a need for power grid simulation analysis example generation technology with configurable new energy installed capacity ratio to meet the research needs of model-driven new control technology.
