Abstract

The analysis of existing mathematical models for power systems with large shares of electricity production by NPP and renewable energy sources generation was carried out. The low level of adequacy is shown for power system models used in the problems of long-term development planning for generating plants with nuclear fuel and renewable energy sources. In order to plan the development of power systems at the current stage of technological changes in the electric power industry, new models of load modes for NPP units and generating equipment with renewable energy sources are proposed. Dispatching models with a cyclic forecast period were used to ensure the adequacy unit commitment models for NPP units and energy storage systems. Representative models of solar and wind power plants are presented, which, together with cluster models of NPP units and energy storage systems, solve the issue on the adequacy of power system modeling in current conditions of their development. The results of computational experiments with the proposed models for generating equipment of the flexible grid are presented. The adequacy of cluster mathematical models of NPP units and energy storage systems, as well as representative models of solar and wind power plants generating equipment is experimentally confirmed.

带小型模块化反应堆的柔性电网发电机组的群集和代表模型

对核电站发电量和可再生能源发电量所占比例较大的电力系统的现有数学模型进行了分析。结果表明，用于核燃料发电厂和可再生能源发电厂长期发展规划问题的电力系统模型的适当性水平较低。为了在电力行业技术变革的现阶段规划电力系统的发展，提出了核电站机组和可再生能源发电设备负荷模式的新模型。使用周期性预测期的调度模型来确保核电厂机组和储能系统的机组承诺模型的充分性。提出了具有代表性的太阳能和风能发电厂模型，这些模型与核电厂机组和储能系统的集群模型一起，解决了在当前发展条件下电力系统建模的充分性问题。文中还介绍了使用所提议的柔性电网发电设备模型进行计算实验的结果。实验证实了核电厂机组和储能系统集群数学模型以及太阳能和风能发电厂发电设备代表模型的适当性。
